The sun, wind, and waves (at least for those of us on the coast) are just outside. Organic matter surrounds us. Yet, it never fails to amaze me how scientists and researchers can turn the seemingly every day and ordinary into something extraordinary and powerful. Take butterflies, for example. One or two fluttering by might make the perfect summer day for you or me; but researchers have discovered that those pretty little wings may actually hold the secret to higher efficiency solar cells. Turns out butterfly wings have scales that act as miniature solar collectors, leading scientists in Japan and China to design a more efficient solar cell that could be used for powering our homes, businesses, and possibly more. Canadian company WhalePower, as their name might suggest, took inspiration for designing wind turbines from the ocean. They were intrigued by the flippers of Humpback whales, which are lined with irregular bumps or tubercles that would appear to promote anything but smooth sailing. Yet, these mammals--all 75,000-plus pounds of them--move with remarkable ease and agility, even swimming in tight circles to capture their prey. As a result of a complex combination of dynamics and biomechanics, wind turbines built with similar tubercles (or Tubercle Technology as WhalePower calls it) demonstrate reduced drag time, increased stable lift and pitch performance--much like the Humpback. Yet another company is following in Mother Nature's footsteps, albeit reproducing what in nature it takes years to grow: trees. Made up of "Nanoleaves," each individual Nanoleaf on these synthetic trees is said to be much like a natural leaf, which flows back and forth in the wind. According to designers Solar Botanic, with multiple Nanoleaves and strong winds, "a tree can produce between 2000 and 12,000 kWh of energy per year." Bear in mind, these trees don't just use wind, but a combination of Nano photovoltaic-Nanothermovoltaic and Nanopiezo generators, which are said to convert light, heat, and wind energy into green electricity (learn more at www.solarbotanic.com). Certainly, we do not lack for ideas, research, or inspiration in the renewable energy sector. The answers to our environmentally conscious energy needs are, at least in part, found within the environment itself. Now the question remains as to how much research will be stunted as a result of a failing economy, at least in North America.

For the latest products and services that will be presented at WINDPOWER 2009 this May, the largest annual wind conference and exhibition in the world, check out page 38. And, this issue's Buyers Guide, which focuses on geothermal energy, is on page 65. We hope this issue inspires even more new ideas, research, and project...from nature and beyond. Photo by Michelle Moore Sincerely, Michelle Froese news bites Report forecasts 37 million jobs from renewable energy and energy efficiency in US by 2030 Energy efficiency programs can reduce growth in electricity consumption by 22% Energy efficiency programs in the United States could realistically reduce the rate of growth for electricity consumption by 22% over the next two decades if key barriers can be addressed, according to an analysis released by the Electric Power Research Institute (EPRI). The potential energy savings in 2030 would be 236 billion kilowatt hours, equivalent to the annual electricity consumption of 14 New York Cities. Stated differently, the demand for electricity over the next two decades could be reduced from the 1.07% annual growth rate projected by the US Energy Information Administration (EIA) in its 2008 Annual Energy Outlook down to 0.83%, slowing the rate of increase by approximately 22%. The analysis comes at a time when utilities, regulators, and policymakers are aggressively seeking ways to meet growing electricity demand while reducing the nation's carbon footprint. The key challenge is to maximize potential gains in energy efficiency while ensuring adequate new electric generation to maintain reliability and meet future demand. The EPRI analysis, entitled "Assessment of Achievable Savings Potential From Energy Efficiency and Demand Response in the US," found that under an ideal set of conditions conducive to energy efficiency programs, the consumption growth rate could be further reduced to as low as 0.68% annually by 2030. However, achieving the ideal would require costly investments as well as political and regulatory support. The report defines a realistic achievable figure that includes a forecast of likely customer behavior, taking into account existing market, societal, and attitudinal barriers, as well as regulatory and program funding barriers. The barriers could reflect customers' resistance to doing more than the minimum required or a rejection of the attributes of the efficient technology. A maximum achievable figure assumes a scenario of perfect customer awareness of utility or agency administered programs and effective, fully funded program execution. The maximum achievable number includes the effect of customer rejection of efficiency technologies. For its baseline assumptions, the EPRI study relied on EIA projections of growth in electricity consumption and peak demand for the residential, commercial, and industrial sectors from its 2008 Annual Energy Outlook. The EPRI report and its executive summary can be downloaded online. "This study is well suited to inform utilities, policymakers, regulators, and other stakeholder groups," said Arshad Mansoor, vice president of Power Delivery and Utilization for EPRI. "Estimates of energy efficiency potential affect forecasts of electricity demand, and electric utilities must make prudent investments in generation, transmission, and distribution infrastructure to reliably and cost-effectively address this demand." Faced with the challenges of managing energy resources wisely, maintaining low-cost reliable power service, and reducing carbon emissions, utilities and policy makers are looking to energy efficiency as a means to achieve these objectives. Many states have established, or are considering, legislation to mandate energy efficiency savings levels. EPRI | www.epri.com The renewable energy and energy efficiency (RE&EE) industries represented more than nine million jobs and $1,045 billion in US revenue in 2007, says a new report released by the non-profit American Solar Energy Society (ASES), which offers the most detailed analysis yet of the green economy. Accordingly, the renewable energy industry grew three times as fast as the US economy, with solar thermal, photovoltaic, biodiesel, and ethanol sectors leading the way, each with 25%+ annual revenue growth. Key conclusions from this report include: � Renewable energy and energy efficiency currently provide more than nine million jobs and $1,045 billion in revenue in the US (2007). � 95% of the jobs are in private industry. � As many as 37 million jobs can be generated by the renewable energy and energy efficiency industries in the US by 2030--more than 17% of all anticipated US employment. � Hottest sectors include solar thermal, solar photovoltaics, biofuels, and fuel cells (in terms of revenue growth). � Hot job areas include electricians, mechanical engineers, welders, metal workers, construction managers, accountants, analysts, environmental scientists, and chemists. The vast majority of jobs created by the renewable energy and energy efficiency industries are in the same types of roles seen in other industries (accountants, factory workers, IT professionals, etc). � Renewable energy and energy efficiency can create millions of well-paying jobs, many of which are not subject to foreign outsourcing. These jobs are in two categories that every state is eager to attract--college-educated professional workers (many with advanced degrees), and highly skilled technical workers. � The renewable energy industry grew more than three times as fast as the US economy in 2007 (not including hydropower). Renewable energy is also growing more rapidly than the energy efficiency industry, but the energy efficiency industry is currently much larger than the renewable energy industry.

By Ed Feo | Milbank Tweed Hadley & Mc Cloy LLP Ed Feo is a partner in the international law firm of Milbank, Tweed, Hadley & McCloy LLP. He co-chairs the Firm's project finance and energy practice and is a member of the Firm's Global Executive Committee. I n my last column, I discussed the status of the discussion in the transition period on energy legislation and, of increasing importance, getting the economy moving again. The slow, downward spiral of the economy in 2008 turned into a sickening dive after the Lehman bankruptcy in September 2008, and the debate on restructuring our energy infrastructure was overwhelmed by the need to stimulate the economy. After the new administration took office, the drumbeat of bad economic news continued. With impressive alacrity, Congress debated and passed, and the President signed, the American Recovery and Reinvestment Act of 2009 (the "Act"), a $789 billion package of appropriations and tax benefits intended to get the economy back on its feet. Renewable energy fares extremely well under the Act in terms of grants, loan guarantees, and tax breaks. Among the notable provisions are the following: The Act requires that grants be paid by the Treasury Department expeditiously, within a period of not more than 60 days after the later of: 1) the date of application, or 2) the placement in service date. However, because of the post-completion funding of the grants, the program will not directly provide construction financing. The Treasury Department is expected to provide guidance in defining what constitutes an application and how "begins construction" is defined. Finally, grants under the program are not taxable income: the Act specifically provides that the grant is not to be included in the recipient taxpayer's calculation of gross income. Enhanced Loan Guarantee Program PTC Extensions The Act extends the section 45 production tax credits ("PTC") for certain renewable energy generating facilities. Under the Act, to qualify for PTCs, wind energy facilities must be placed in service by year-end 2012. Qualifying closed- and open-loop biomass, geothermal, landfill gas, municipal solid waste, hydropower, and marine and hydrokinetic facilities (together with wind, the "eligible facilities") must be placed in service by year-end 2013. No PTC extension is provided for small irrigation power, refined coal, and Indian coal production facilities. ITC Election In lieu of claiming PTCs, the Act allows qualifying wind, closed- and open-loop biomass, geothermal, landfill gas, municipal solid waste, hydropower, and marine and hydrokinetic facilities placed in service after December 31st, 2008, and before the relevant PTC expiration date (year-end 2012 in the case of wind, and year-end 2013 for all others) to elect an investment tax credit ("ITC") for 30% of the costs of new equipment. Prior to the Act, only solar facilities were eligible for the up-front 30% ITC. Geothermal facilities had been permitted a 10% ITC, but this is increased to 30% by the Act. Bonus depreciation, permitting an additional depreciation deduction equal to 50% of the adjusted basis of property, is extended to eligible property placed in service in 2009. Section 45 has also been amended to permit a lessor of an eligible facility to qualify for the PTC (or ITC). Previously, this financing device was only available for certain biomass facilities. Renewable Energy Grants The Recovery Act expands the current federal loan guarantee programs under Title XVII of the Energy Policy Act of 2005 to permit loan guarantees for proven renewable energy, transmission, and biofuels projects. The new program makes loan guarantees formerly available only to "new or innovative technologies," now available for: 1) "renewable energy systems, including incremental hydropower, that generate electricity or thermal energy, and facilities that manufacture related components," 2) "electric power transmission systems, including upgrading and reconductoring projects," and 3) "leading edge biofuel projects." Loan guarantees under the new program are available for projects that commence construction no later than September 30th, 2011. In addition, the Act appropriates $6.0 billion to pay for the costs of loan guarantees under the new program. This appropriation to subsidize the cost of loan guarantees is expected to support $60 billion in loan guarantees. Furthermore, Secretary of Energy Steven Chu has committed the DOE to begin offering loan guarantees under the augmented program by early summer 2009, and to disperse 70% of the Recovery Act investment by December 2010. Secretary Chu has indicated that he will streamline and simplify the loan application process, defer the payments of fees to closing, permit accelerated underwriting by outside partners, and allow rolling appraisals of applications. What are the Consequences for Financing? The ability to claim a cash grant in lieu of a tax credit is, perhaps, the most remarkable option afforded by the Act. Under the innovative new program, the monetization of tax credits is provided directly by the government: the Act directs the Department of Treasury to issue grants equal to 30% of the cost of facilities that would otherwise qualify for the ITC. The grant program is available for 30% of the cost of eligible facilities, 30% of the cost of fuel cell, solar, and small-wind energy properties that qualify for the ITC under Section 48, and 10% of the cost of qualified microturbine, combined heat and power, and geothermal heat pump property. No PTC or ITC may be claimed for facilities for which a grant was made. The program is designed to spur development in the near-term. As such, to be eligible for a grant, a project must either: 1) be placed in service in 2009 or 2010, or 2) initiate construction in 2009 or 2010 and be complete by the "credit termination date," defined as 2013 for wind; 2014 for closed- and open-loop biomass, geothermal, landfill gas, municipal solid waste, hydropower, and marine and hydrokinetic facilities; and, 2017 for fuel cell, solar, small-wind energy, and other properties that qualify for the ITC under Section 48. 8 March / April 2009 nacleanenergy.com A few of these provisions merit further discussion... The extension of the PTC for three years, the option to elect an ITC in lieu of the PTC, and the availability of a grant in lieu of claiming the ITC on a tax return are all good news for renewables relying on the federal tax incentive scheme. Tax incentives are fine if there are taxpayers able to use them. But the combination of restrictive tax rules, plus the financial services sector meltdown has meant that there have been only a handful of investors actually able to monetize these benefits. The grant in lieu of credit scheme means the federal government is replacing the tax equity investor in monetizing the ITC--and at a rate in excess of the value that a private investor would offer. The next challenge involves what to do with accelerated depreciation, the other federal tax benefit available to these projects. With the ability to engage in a financing lease for any renewable project, the optimal structure would appear to be a lease of the project, with the tax equity investor being the lessor and using the depreciation. We believe that these transactions can be structured such that either the lessee or the lessor may receive the ITC grant (and there may be better reasons in terms of tax efficiency for the lessee to take it). This lease could then be leveraged with debt. Although this approach seems the most efficient scheme, there is one problem: there are not enough tax equity investors in the current market willing to absorb the early year losses incurred with accelerated depreciation. So, what's the solution? It may be that for many projects, the capital structure will be the ITC grant (think of this, essentially, as a buy down equal to 30% of the installed capital cost of the project) with the remaining portion of the capital structure covered by senior debt and any remaining gap filled with pre-tax equity or mezzanine debt. In this structure, the project sponsor, as the continuing owner, will absorb the deprecia- tion, booking losses in the years of accelerated depreciation, and carry those losses forward to later years when the project generates taxable income. Though this is not as efficient as a front-end monetization of the depreciation (if for no other reason than the time value of money to the sponsor), it may be the easier deal to do in the market of 2009. So, who isn't excited about the ITC grant? Any project that qualifies for PTC and has a high capacity factor. There are a number of e-mailed tables circulating in the project finance world showing the crossover where the project capacity factor makes the PTC preferred to the ITC. The math can be simply stated as: 2.2 cents/kwh times high output has a higher net present value than 30% of the capital cost. Geothermal projects, in particular, are disadvantaged because they have very high capacity factors. What's the upshot? There is a market of projects where private investors can provide a better deal than the federal government, and we expect that the tax equity world (as small as it currently is) will be focused on these projects. What about debt? The debt market actually seems to have hit bottom. There are a number of lenders still in business, although this number is reduced and their hold positions may be lower. The lenders include some of the companies formerly active as tax equity investors. The consequence is that deals currently are looking at $200 to $300 million as the maximum amount of debt. Although this level should rise as the financial sector recovers, for the time being the effect is that portfolio transactions (grouping together a number of projects into one transaction) are less likely, and mid-sized single asset deals are in the sweet spot of the market. Rates, of course, also reflect the financial times. Margins on senior debt are in the 300-plus basis point range compared to less than 200 a year or more ago. Mezzanine debt, a slice of current focus from private equity firms, carries a pre-tax rate in the mid-teens. Unless, of course, we consider the effect of the federal loan guarantee program. The existing federal loan guarantee program did not advance much of anything, as no guaranties were granted, mainly as a result of underfunding and understaffing of the Department of Energy Loan Guarantee Office. But the current administration has made it clear that the guarantees and grants contemplated by the Act will move out the door briskly. The principle benefits of the federal loan guarantee will be to permit larger-scale financings, for a longer term and at lower rates on debt, than the current market will be able to offer without a guarantee cover. For larger projects, especially with newer technology, we expect the federal loan guarantee program to be the way to financial close in 2009. The interesting issues, among others, will be how the Department of Energy decides to prioritize among very different competing technologies (commercialized large-scale wind versus less commercialized large-scale solar thermal, or for that matter even less developed technologies), and how the federal loan guarantee program will fare in terms of default risk given the current push to get money out the door. What's next? The Administration is moving forward with additional energy legislation to address other challenges to the conversion to a flexible, green electric system. We should expect the federal renewable portfolio standard to receive much attention. Transmission siting will be on the agenda. Bills are already circulating on both topics. And, of course, at some point in the next two years, climate change legislation. How the politics of these portions of the energy agenda play out is not yet clear, in light of the extraordinary priority of economic recovery. Stay tuned!

A good supplier proposes key benefits for an operation--this is a live process, one that continually seeks better ways and alternatives to improve operations. In short, identify and partner with suppliers that understand the wind sector, can aid with localization efforts, and transfer practices that positively impact operations. Healthy balance sheet. It is important to consider the financial condition of all critical or "tier 1" supplier relationships. Far too often, manufacturers are forced to terminate supply agreements due to under-capitalized manufacturers supplying critical path components, lacking the resource or capacity to scale, or meet the dynamic needs of turbine, tower, and blade manufacturers. Establishing long-term relationships, while ensuring key suppliers are well managed, have proven track records, and can support a company's goals are important considerations. There are many operating risks in managing today's global supply chain, and companies would be wise to eliminate or reduce as much credit and capitalization risk, particularly in the volatile financial markets we have now. Stable material supply. Original Equipment Manufacturers (OEMs) should focus on securing critical path components. Whether pursu- We are experiencing a difficult eco- nomic environment, and many manufacturers in the wind sector are evaluating long-term partnerships to position their businesses for short-term profitability and longer-term share growth. The ability to properly assess strategic partnerships and, ultimately, select preferred suppliers is critical for ongoing competitiveness and profitable growth. Strategic sourcing teams for turbine, tower, blade, and nacelle manufacturers are being challenged to contribute to the global growth of their companies. A need to develop a strong supply chain among diverse operations is becoming an important consideration in terms of market entry acceleration, competitive positioning, and long-term viability. Highlighted are a few key elements strategic suppliers should embrace when considering a partner for a supply chain. Every single component or service is reflected in the end product, the brand, the market position and, ultimately, in a customer's perception. When evaluating strategic partnerships, it is important to evaluate all of the company's requirements, so as to establish a lasting relationship, to achieve competitiveness, and profitable growth. Global. With an interest in pursuing new markets and accelerating the efficiency of new operations, a global scale is increasingly important. Today's requirement for the expansion of renewable energy, and the rapid expansion of new markets, demands a truly global partner that can help accelerate entry into these markets, while seamlessly integrating existing operations and associated business practices. Wind industry expertise. Partnering with a supplier that has industry expertise is of great importance. Considerations for existing suppliers, as well as for pending supplier qualifications, include: benefitting from those suppliers that can offer the best practices to accelerate localization, optimize ing a vertically integrated strategy or securing critical components via an out-source model, resources should be focused on critical component supply. Supplier rationalization, which is common in many other industries, is becoming more important in the wind sector. Global sourcing and localization is essential to assure competitive pricing and the right mix in a product portfolio. Finding the balance to ensure resources are allocated strategically, while maintaining consistent quality and proper inventory positions of critical and noncritical parts that support manufacturing and project implementation, is becoming increasingly significant. Robust quality system. One of the most important decisions is material quality. Ensuring quality control and consistency in manufacturing routines is critical to ensure delivery of quality components. Eliminating any variation in results is key, so components or materials will perform as designed for the expected life of the turbine, significantly reducing field failure, and downstream costs associated with remediation. Increasing the importance of quality evaluation in the supplier selection criteria involves a delicate balance between localization requirements, resource constraints, and logistics constraints as OEMs expand into new markets. A prospective supplier's quality infrastructure is an important consideration, one that with due diligence should evoke confidence that the product or service is meeting overall quality requirements. Working capital. Cash flow is a hot topic, particularly given the global financial crisis, and the impact on project and delivery delays. The ability to rapidly adjust to production and project schedule changes is vital. Equally important as the ability to react to demand changes is a capacity for global inventory re-balancing. Partners should improve working capital and accommodate changing global business conditions, while providing a significant operating and financial impact. Business practices. Integrity and ethical business practices are the foundation for sustainable business relationships. The aforementioned elements are all significant; however, ensuring your supplier selection closely evaluates general business practices and fosters a culture of openness will cement a lasting and mutually beneficial business relationship.

This difference may be driven by the uncertainties in wind power predictions and in the operation of the wind power plant. Accurate wind speed readings are important in wind project site performance through the use of wind turbine power curves and historical wind speed distributions. Fundamentally, wind power is proportional to the cube of the wind speed, translating small errors in wind speed measurements to a much greater error in the wind energy production estimate. To achieve required measurement precision, it is recommended that calibrated anemometers be employed and post-deployment calibrations be performed as a check on the process. Anemometer calibration is essentially the relationship of the anemometer's raw output to a reference wind speed measurement. Performing anemometer calibrations provide an important quality check on a resource assessment project, but it is equally important to assure the quality of the calibration performed. Factors to consider R when selecting a qualified test laboratory include: 1. Calibration test method 2. Test facility capability 3. Personnel background and experience 4. Quality management system accreditation 5. Participation in inter-laboratory comparisons 1. Calibration test method to recognized national standards, such as NIST (National Institute of Standards and Technology). As required by published standards, test methods should record and report all relevant variables during each test, including local test conditions such as temperature, barometric pressure, and humidity. 2. Test facility capability Anemometers are calibrated in a wide variety of test methods, including sideby-side sensors on a meteorological tower, outflow from a pipe or fan, moving vehicle, and multiple sensors in a wind tunnel. According to test methods defined in standards, it is generally accepted that only wind tunnels with one anemometer at a time provide the required level of control over experimental variables. Wind tunnel reference sensors can be Pitot tubes, hot wire anemometers, LDV (laser Doppler velocimetry), or model substitution. It is important to use reference sensors that are traceable to internationally recognized standards. Currently, most qualified laboratories in the wind industry use Pitot tubes (with related sensors and transducers) traceable Considerations for test facility capability should include investigations in the applicable test speed range, facility flow quality evaluation, and uncertainty for each measurement point. For wind energy applications, a recommended test speed range is 4 m/s to 26 m/s, which matches the typical range of wind turbine cut-in speed (4 m/s) and cut-out speed (26 m/s). It is particularly important to review the facility flow quality since the basic idea of calibration is to find a quality representation of wind speed to the signal output of an anemometer under test. Uncertainty is essentially the key value that represents the quality of the test lab, since it summarizes all the possible factors that could affect the calibration. Other important factors for evaluating the capabilities of a test facility include the method of sensor installation at the appropriate location, the ability to record the anemometer output signal along with other test variables, and the time required to complete the work. Regardless of the test method, a sensor is installed in a test facility so that its presence does not disturb the measurement of the local wind speed. To have a quality calibration, the reference wind speed is essentially a measure of the undisturbed wind ahead of the anemometer under test. For most rotating anemometers, output signals may present some type of a waveform whether a sine wave, square wave, or even an impulse. Consideration must be made to the method at which a test lab would read such signals, and converting the signal into a measured rotating rate or frequency. A final capability consideration is the time required to complete the work; customers involved in tower installations may require faster turnaround times to meet project deadlines. 3. Personnel background and experience Experience of laboratory personnel should also be reviewed. Relevant experience includes wind resource assessment work, measurement and instrumentation experience, knowledge in atmospheric boundary layer meteorology, background and training in aerodynamics, and experience with experimental methods. To design the capabilities of a test facility for calibrating anemometers, laboratory personnel should have basic knowledge in fluid flow and laboratory instrumentation. To understand the application of anemometer calibration, background in field assessment and atmospheric meteorology is critical. Continuous participation in the wind industry would reflect the overall experience of the test facility. 4. Quality management system accreditation A quality management system accreditation is recommended. The most commonly used accreditation standard in test laboratories is ISO/IEC 17025:2005. Laboratories use ISO/IEC 17025:2005 to implement a quality system aimed at improving their ability to consistently produce valid results. It is also the basis used by an independent accreditation body to assess test laboratories. Since the standard is about competence, accredita12 March / April 2009 nacleanenergy.com tion is a formal recognition of a demonstration of that competence. 5. Participation in interlaboratory comparisons Windmill breakthrough Participation in inter-laboratory comparisons is critical. Inter-laboratory comparisons provide an external check on the validity of laboratory results. For this case, it is critical to investigate a common sensor and the methods used to perform inter-laboratory comparisons. In the mid-1980s, a comparison program was started using an RM Young Propeller designated as the Round Robin 2 (RR2). This program continues to be active and has included test labs from all over the world. Inter-laboratory comparisons have also been performed by MEASNET, the international Measuring Network of Wind Energy Institutes. Some members of MEASNET include laboratories in Germany, Denmark, Spain, and Greece.

North American Clean Energy 13 wind energy View from the Top Fall protection and rescue during wind turbine construction By Steve Jervis T he view from the top of a newly constructed wind turbine is spectacular. Standing atop the nacelle, the worker can see for miles around, a perspective that only those brave enough to work at extreme heights can enjoy. Along with the rolling vista, however, the ground--often hundreds of feet down--is only one spine-chilling glance away. For those who work in the wind turbine construction industry, fall protection is a primary safety concern. The world's tallest wind tower reaches a height of almost 525 feet (160 meters), and with new construction continuing to push the limits, workers are exposed to a unique set of dangerous fall hazards. After the infrastructure and foundation work has been completed at a construction site, individual sections of a tower will be installed. This involves work from a ladder system installed within the tower sections, which may or may not have a vertical fall arrest system in place. If a cable or rail ladder safety system is not in place, one can be specified and installed onsite. A ladder safety system is designed to stop or arrest a fall should a worker slip or let go of a rung. Running the length of the ladder, this system can either be a stainless or galvanized steel cable, or an aluminum or stainless steel rail. A shuttle or sleeve connected to the system attaches to a worker's full-body harness and follows the worker's movements up and down the ladder. Should a fall occur, a brake will engage in the shuttle/sleeve to arrest the fall. Once a tower is complete, the nacelle (the structure at the top of a tower, housing the electrical control units and generator) will be installed. This will require installation of cabling that runs the length of the tower, which can be completed from a service lift or ladder. If using a service lift, a full-body harness connected to a lanyard and tied off to the lift should be worn. If working from the ladder, a restraint or work positioning device should be used to allow a worker use of both hands--and this should be in addition to the fall arrest system. When the rotor (the combination of the blades and hub) is lifted in preparation for attachment to the nacelle, workers will need to be outside, atop the nacelle. In almost all cases, built-in anchorage points will be available for connection of a shock absorbing lanyard or self retracting lifeline (SRL). Before a worker steps onto the nacelle, he or she should attach one end of the lanyard or SRL to the anchor, and the other end to the dorsal D-ring of his or her harness. Twin-leg lanyards and SRLs offer an advantage as they allow for 100% tie-off. Should a worker need to switch anchorage points, he can keep one leg of the lanyard connected to the first anchor point, while he connects the other leg to a second anchor point. Upon connection to the second anchor point, he would remove the leg connected to the original anchor point. Other anchorage options for the nacelle are tie-off adaptors, which can be wrapped around a structural member to create an anchor point, or self-contained vacuum anchors that operate with onboard compressed air to provide a secure anchorage point. Benefits of a vacuum anchor include its portability and ability to be placed anywhere on the structure. Though it is important to ensure the vacuum anchor is rated for fall arrest. One of the most important considerations for fall protection during wind turbine construction is rescue equipment. Should a worker fall from the top of a nacelle, rescue by conventional means will be virtually impossible. To compound the problem, speed is of great importance when it comes to rescue because a worker may have suffered an injury that led to the fall, or been injured during the course of the fall--or both. Furthermore, a worker suspended in a harness may develop suspension trauma, a condition in which lack of motion and constricted veins may cause blood to pool. Suspension trauma does not always result in long-term injuries, but the possibility demands prompt attention. The often remote location of wind farms necessitates trained rescuers be available at the job site as emergency services may not be able to respond very quickly. They may also lack appropriate equipment for the rescue, which is why equipment that is simple to use and quick to set up must be kept on site. Suspension trauma can be avoided by the provision of suspension trauma relief straps, worn by every worker on his or her harness. The straps also give rescuers a much more relaxed period in which to perform a rescue, preventing any potential accidents from rushed connections. Evacuation may become a necessity if a complete mechanical failure or fire occurs on 14 March / April 2009 nacleanenergy.com the turbine. Rapid descent, available for multiple users, is an absolute must for construction crews. Equipment such as an automatic descent control device or evacuation device can be used for both evacuation and rescue. Pre-engineered pulley based rope rescue systems and remote rescue systems can be used to rescue fall victims. The turbine should be properly equipped with self-rescue, personal evacuation, and emergency evacuation equipment at multiple points, including the tower and nacelle. Fall protection equipment selection should be a part of a larger fall protection program, in which a hazard analysis is conducted, control methods are determined based on the fall protection hierarchy and workers are thoroughly trained. For more information on how to create such a program, take a look at ANSI Z359.2, a voluntary consensus standard covering fall protection for general industry in the US (the full publication is available, for a cost, at www.ansi.org.

Experience. Technology. Answers. MEMBER he propellers of large scale wind turbines have become the global icon for wind energy. Most clean energy publications and renewable energy websites feature images of towering, mega-scale propeller turbines. Large propeller turbines, also known as horizontal axis wind turbines (HAWTs), are the standard in the large wind industry due to their excellent efficiency in converting wind to power. However, what makes them ideal for large scale wind farms (large and remote open spaces with consistent wind direction) does not necessarily make them a great fit for urban sites. Conversely, the traditional limitations of vertical axis wind turbine (VAWT) technology for wind farm applications can turn into advantages for more urban locations. Increasingly, homeowners and small businesses are considering VAWTs to help overcome the challenges associated with many small wind sites. It is important to recognize the difference between HAWT and VAWT technology to understand why each is well suited to particular applications. HAWTs have blades that rotate vertically around a horizontal axis, similar to a propeller on an airplane. Propeller turbines need to be oriented perpendicular to the direction of the wind to be efficient and, in variable or more turbulent wind conditions, they need to constantly re-orient themselves, losing efficiency in the process. Propeller blades are designed to use "lift" (differential air flow in front of and behind the blade) to propel themselves around faster than the speed of the wind. While the part of the blade near the hub turns at a reasonable speed, due to their rigid outstretched blades, the tips whir around at greater speeds (think of a parade line turning the corner). Typically, the tips of blades speed along at seven to ten times the speed of the wind (known as a "tip speed ratio" of 7-10). Although propellers are efficient in using lift to maximize energy transfer and electricity production, the main drawback in an urban setting is that their tip speeds can create high levels of noise, which can be bothersome to neighbors. More modern HAWT designs seek to lessen noise by employing special curvature in the blades. The high speeds also add strain on the blades so, to keep them safe, turbines (especially propeller style turbines) require use of special braking controls. One common method of braking is "furling," when the propeller re-orients itself perpendicular to the wind to stop it from turning. As it turns, it makes a resounding roar--which is not a major problem if it happens occasionally, but it can be very noisy in high, gusty winds. Lastly, while wind direction in the open spaces of wind farms is fairly consistent, wind direction in urban settings is often changing. HAWTs are not able to adapt quickly to changing wind directions and, therefore, operate extremely inefficiently in more turbulent conditions, as compared with VAWTs. VAWTs include two main classes: a tall vertical airfoil style (Darrieus), and a solid winged style (Savonius). Darrieus Turbines come in a few varieties. Some have rotors with curved blades that look like an eggbeater and rotate about a vertical axis. Another variation uses straight-sided airfoils and is called a Giromill. Like propeller turbines, Darrieus turbines utilize some lift to capture wind energy and operate with tip speed ratios in the lower-middle range: their tips spin slower than propellers, but faster than Savonius designs. Savonius Turbines have rotors with solid vanes or "scoops" that rotate about a vertical axis, using "drag" to allow the wind to push them around. Savonius turbines provide very high starting torque and they typically start rotating in the slightest wind. The principle drawback of Savonius turbines is that drag produces far lower energy efficiency than the other 16 March / April 2009 nacleanenergy.com SCADAPack controllers Control Microsystems' SCADAPack 330E and 334E are two of the latest additions to the SCADAPack family of telemetry and control devices.

All SCADAPack E-Series controllers come with a three-year warranty. Control Microsystems | www.controlmicrosystems.com types of wind turbines. Most anemometers (wind measuring devices) are a form of a Savonius turbine. Traditionally VAWTs are not recommended for large wind energy production because they are a little less efficient than HAWTs, and they do not scale as well to very large applications. However, the ability of VAWTs to operate silently and efficiently in variable and turbulent wind conditions make them a viable option for urban locations in which these are common site characteristics. The fact they operate at lower RPMs and with tip speed ratios only two to three times the wind speed means they can produce power without creating noise. VAWTs also readily capture wind energy from any direction, allowing them to work with the constant changing wind directions in urban settings. At the end of the day, the most important factor is power output. If a VAWT is able to provide ample energy output in an urban setting, then it is a real option for homeowners, small businesses, and governments to consider. For those considering urban installations, it is important to research the various VAWT and HAWT turbines. There are currently no standards in place for measuring performance in small wind turbines, so it is important to look for products with independent testing and realistic claims, based on how large the rotor is and how much energy the manufacturer is claiming the turbine will provide. It is also important to do a solid assessment of wind at the site by evaluating if wind speeds are adequate for decent power production, if the site is open enough to avoid huge obstacles, and what levels of turbulence and gustiness are in the area. With the right wind and siting conditions, small VAWTs offer consumers and small businesses the opportunity to participate in renewable energy on a more personal level.

To help preserve the delicate ecological balance of this world heritage site, the government of Ecuador has embarked upon a mission to eliminate fossil fuel-based power production from the Galapagos archipelago by 2015. As the first step in this initiative, the community of San Crist�bal is employing renewable energy technology as an environmentally friendly complement to the island's existing diesel-powered generating plant. In 2007, San Crist�bal's new wind energy facility came online as part of a hybrid wind-diesel solution, generating electricity for the island's 6,000 inhabitants while reducing the community's diesel fuel consumption by half. Appropriately, even the flashing obstruction lights that sit atop the three giant wind turbines use renewable energy (in this case solar energy) as a showcase of environmentally friendly technology at work. Adapting to life on the islands By Anthony Tisot Harnessing the power of the wind Concerns about the risk of environmental contamination proved valid when, in January 2001, the Ecuadorian tanker "Jessica" ran aground at the entrance to Puerto Baquerizo Moreno on San Crist�bal Island, spilling 160,000 gallons of diesel oil into the fragile ecosystem. Though a combination of favorable currents and a determined response by Galapagos National Park Service staff, local fishermen, and volunteers helped to lessen the extent of the damage, the incident underscored the need for a more sustainable and environmentally friendly source of energy for this unique location. Located on the equator some 600 miles from the coast of Ecuador, the Galapagos archipelago consists of 13 large islands and more than a hundred smaller islands, islets, and rocks that are home to some of the world's rarest birds and sea creatures. Although mariners have frequented the islands for 500 years, attempts to maintain self-sufficient communities in this remote location have historically proven challenging and, at times, problematic. Invasive plants and animals introduced intentionally or incidentally over the years have plagued the native species and threatened their habitats. Ongoing efforts to restore and protect the region's ecological balance have seen some success but, in recent years, a new threat emerged as the growing communities and expanding tourist trade demanded ever-more energy from the region's existing diesel-based power generation facilities. Fortunately, today's renewable energy technologies offer a range of alternatives that can help minimize the ecological impact and risks of traditional energy sources. In its role as steward to this irreplaceable ecosystem, the Government of Ecuador prepared to implement a renewable energy solution in the form of a $10.8 million, 2.4-megawatt wind farm on San Crist�bal Island. The San Crist�bal Wind Project would be built in partnership with the United Nations Development Program (UNDP), private businesses in Ecuador, and the e8--a non-profit organization of the world's largest electricity companies dedicated to promoting sustainable energy development worldwide. To reduce diesel consumption, while ensuring a reliable power supply in all seasons, the project's three massive wind turbines would work in conjunction with San Crist�bal's existing 650 kilowatt diesel generators. Together, this hybrid wind-diesel system would fulfill the island's power requirements while reducing CO2 emissions by an estimated 2,800 tons per year and cutting diesel fuel shipments by fifty percent.

Another benefit was the lights' ability to endure vibration and buffeting from the elements while shielding all components-- solar modules, batteries, LEDs, and electronics--within a compact and durable enclosure. Madrid-based Made Tecnolog�as Renovables to supply the wind turbines, diesel automation, and hybrid control equipment; SANTOS-CMI of Ecuador to construct the turbines onsite; and ELECDOR of Ecuador to install the transmission line. Choosing a suitable location The turbines' location was carefully chosen to minimize any impact on the region's indigenous species, such as the Miconia plant and the Galapagos Petrel, an endangered seabird that nests on the island. As part of a stringent environmental impact assessment, extensive research was conducted to determine the typical flight paths and areas favored by the petrel. Based on the findings of this research, a suitable project site was identified at El Tropezon--a location in the highlands, well away from the areas where the petrel typically flies and nests. To further reduce any danger to the petrel and other local birds, potential obstacles were eliminated wherever possible; transmission lines were buried underground, fencing was minimized, and the turbine towers themselves employed a design free from tension wires or lattice. A solar-powered lighting solution As the first stage of an umbrella program to implement renewable energy alternatives throughout the Galapagos archipelago, the San Crist�bal Wind Project is a remarkable achievement. While reducing air pollution, cutting fuel deliveries, and introducing an affordable and inexhaustible source of electricity to the region, the hybrid wind-diesel system provides a functional link between traditional fossil fuel-based technologies and the new generation of sustainable energy alternatives. Since the project's completion in October 2007, San Crist�bal's new wind-energy facility has performed according to plan, supplying more than 50% of the island's energy needs through wind power. Though it can supply up to 80% of the island's electricity during the region's windiest season, the facility can also work in conjunction with additional alternative energy technologies to further reduce the community's reliance on diesel generation. To this end, the project also includes a number of PV panels connected to the island's electricity grid. The solar panels, donated by the e8, represent an additional source of clean energy that can help to demonstrate the potential of a solar-powered solution, while providing the means to train local utility staff on yet another renewable energy alternative. Looking ahead With two airports in the vicinity, effective obstruction markers were a necessity on the three 50-meter tall structures; although, as lighting can sometimes prove hazardous to birds, these too were chosen with care. For this project, Made Tecnolog�as Renovables selected a set of solar-powered LED (light emitting diode) obstruction lights from Canadian manufacturer Carmanah Technologies Corporation. Initially designed for the United States Air Force and approved for use in the Galapagos by the Ecuadorian Aviation Authority, the solar-powered obstruction lights were found to be an effective and environmentally friendly lighting solution. Suitable for locations with limited access to sunlight, the stand-alone beacons require just 1.5 hours of sunlight per day to operate effectively--a valuable asset in an area where seasonal con- As Ecuador's first large-scale wind project and one of the largest wind-diesel hybrid systems in the world, the San Crist�bal Wind Project is a milestone in sustainable development, equally notable for the scale and innovative design of the project, as for the shared commitment to environmental conservation and sustainable development that has characterized each stage of this six-year endeavor. Following the successful completion of the San Crist�bal Wind Project, a second renewable energy project is underway for the archipelago. In 2008, the Project for Renewable Energy for Galapagos (ERGAL) announced a proposed 3.2 MW wind energy project to accommodate the islands of Baltra and Santa Cruz. With the San Crist�bal Wind Project leading the way as an example of environmentally friendly energy generation, Ecuador is making significant progress towards its goal of eliminating diesel-based power generation from the Galapagos Islands.

The Princess Elisabeth Station was officially inaugurated in Antarctica on February 15th, 2009. This station is the only polar base operating entirely on renewable energies. It marks a major change as most stations rely on diesel generators because no wind turbines, until now, were thought to be robust enough for such extreme conditions. The turbines will endure the most severe weather conditions on earth. They will be operating in average winds of 53 mph and winter gusts of over 200 mph, while still providing 230V electricity for the stations heating, computers, lights, and scientific instruments. The electricity generated is expected to be the highest output of any small wind power system in the world. Proven Energy, a Scottish based small wind turbine manufacturer, supplied the 6kW wind turbines. The turbines are designed to work in extreme environments. Previous installations have weathered ice storms in Slovenia and typhoons in Japan. The official launch represents a technical achievement, blending the best both science and technology can offer. By bringing together international technology and expertise, Princess Elisabeth will combine eco-friendly construction materials, clean and efficient energy use, optimization of the station's energy consumption, and the best waste management techniques. These techniques and facilities will aim to reduce the station's ecological footprint on the pristine environment of Antarctica, following the principles set forth by the Antarctic Treaty. In addition to the turbines, both solar thermal and photovoltaic (PV) will be used on the building itself. The water supply for the station will use solar thermal panels to melt the snow, thereby limiting the use of electrical energy to pump water. Proven Energy | www.provenenergy.co.uk | www.antarcticstation.org Emerging Energy Research's annual "Wind Turbine Market Share Update" reveals a 2008 global turbine market in which high demand and supply chain backlogs offered plenty of room for all: established players averaged installation growth of more than 50%, while several newer players saw installations jump by 100%, and more. Buoyed by 2007s bursting order books, turbine manufacturers installed almost 11 GW more turbines in 2008 than in the previous year--totaling nearly 30 GW of turbines activated during the year, almost double the volume in 2006, with the US and China accounting for 48% of that amount. "The battle for market share is expected to intensify in 2009-2010 as the economic slowdown continues, and as local suppliers in the United States and China ramp production," says Keith Hays, EER research director. Players with diversified order books are best positioned to grow in 2009 as the slowdown will be felt most acutely in the US, a market that weighs heavily in the order books of the major vendors. At the same time, China remains less impacted by the recession; steady performance can be expected from China's growing number of local turbine suppliers, as well as global players, with an existing foothold in that market. Investments and plant capacity expansion point to a collective optimism on the part of many manufactures for the long-term market, despite their expectations for modest growth in 2009. "The industry saw record installations in 2008, even though new production facilities had not yet come on line in the US and China," said Hays. "With an improving market in 2010, manufacturers with capacity expansion plans, such as Acciona, Gamesa, Suzlon, Siemens, and Vestas, will be well-positioned for the recovery, although full utilization will depend on their ability to demonstrate flexibility in pricing and delivery terms." EERs "Global Wind Turbine Market Share Update" is developed annually by their Wind Energy Advisory research team, and uses on-the-ground research combined with extensive access to key players in global wind energy industry. Emerging Energy Research | www.emerging-energy.com It is no mystery that much of the focus for the American economy in the coming years will be on renewable energy sources, with wind power at the forefront. Wind industry experts know that utilizing wind as a major new source of energy will require a huge effort. The entire infrastructure needs to be addressed, including the power grid network and manufacturing capabilities, as well as training the huge numbers of workers needed to build and sustain the wind-generation system. This effort will require an unprecedented collaboration among industry participants from all levels of government, manufacturing, service, and education. To this end, Snap-on Industrial, a division of Snap-on Tools Company, recently convened an industry consortium at its Kenosha, Wisconsin manufacturing facility to talk specifically with key members of industry, trade associations, labor groups, government officials, and technical colleges about the future needs of both the American and global wind power markets. Some industry experts estimate that manpower requirements to service this market over the next several years could reach 200,000 workers. "It was our goal to bring together in one room people who not only see the need to train the next generation of technicians in the wind power industry, but people who can make that happen," said Frederick Brookhouse, senior segment sales support manager-education, Snap-on Industrial. Representatives of the newly formed group, tentatively named Wind Energy Training Consortium, met in January of this year to discuss partnership development, implementation of wind technician training, and tooling requirements. Snap-on Industrial | www.snapon.com 20 March / April 2009 nacleanenergy.com Wind Energy Training Consortium Renewable energy accounts for largest share of annual increase in US electrical generating capacity For the first time ever, non-hydroelectric renewable energy, led by wind power, was the leading source of new electric generating capacity in the United States, according to a recently released report, "Electric Power Annual 2007" from the US Energy Information Administration. The study found that in 2007, electric power generation increased 2.3%, from 4,065 million megawatt-hours (MWh) in 2006 to 4,157 MWh in 2007. Total net summer capacity increased 8,673 MW. Wind capacity accounted for 5,186 MW of this new capacity. So, for the first time ever, renewable energy sources, other than conventional hydroelectric capacity, accounted for the largest portion of capacity additions. Net generation produced by renewable energy sources, excluding hydroelectric generation, grew by 9.0% as compared to 10.5% growth in 2006. Renewable energy accounted for 2.5% or 105 million MWh of total net generation in 2007. This marks the fourth consecutive year in which renewables share of total net generation has increased. In 2007, wood and wood derived fuels accounted for 39 million MWh or 0.9% of total net generation. These fuels continued to be the largest sources of renewable generation, accounting for 37.1% of total net renewable generation, excluding conventional hydroelectric generation. Wood and wood derived fuels have maintained fairly stable output levels averaging 38 million MWh per year. Other biomass supplied 17 million MWh of net generation. It has declined from a 23 million MWh peak in 2000 to 17 million MWh in 2007. Wind generation was the second largest renewable energy source, contributing 34 million MWh or 0.8% of total net generation in 2007. It is rapidly gaining a larger share of total renewable generation. In 2007, wind accounted for 32.7% of total net generation from non-hydroelectric renewable sources, as compared to 4.3% in 1997. The annual growth in solar thermal and photovoltaic generation has been sufficient for this renewable source to account, on average, for 0.5% of all non-hydroelectric renewable energy. Geothermal power plants contributed 15 million MWh of net generation and accounted for approximately 0.4% of total net generation in 2007. Geothermal has maintained fairly stable output levels averaging 15 MWh per year. Conventional hydroelectric power continues to decline as a share of total net generation. It declined 14.4% from 289 million MWh in 2006 to 248 million MWh in 2007. In 2007, conventional hydroelectric generating capacity accounted for 6.0% of total net generation, as compared to 10.2% in 1997. The decline in conventional hydroelectric generation is consistent with the drought conditions, which according to the National Climatic Data Center (NCDC) prevailed over the West and Southeast for much of the year. According to NCDC, evaporation caused by above normal summer temperatures exacerbated drought conditions in these regions. Moreover, precipitation was below average in the Southeast and the mountain snowpack in the Rocky Mountain and Western States was significantly below normal levels. The report "Electric Power Annual 2007" was issued by the US Energy Information Administration on January 21st, 2009 and be found online at: http:// www.eia.doe.gov/cneaf/electricity/epa/ epa_sum.html. North American Clean Energy 21 solar energy The Race to Develop Utility Scale Solar Projects Project siting, permitting, timing and more By Connie Farmer W ith the world's increased emphasis on renewable energy development, utility scale solar technologies are becoming a more attractive form of renewable energy generation. New incentives for renewable energy proposed under the economic stimulus package will only heighten competition for viable solar sites. The development of these types of facilities requires the acquisition of large tracts of relatively flat land. While some developers are working with private land owners to acquire project sites, the majority of these projects are being proposed on public lands in the Southwest, primarily on lands managed by the Bureau of Land Management (BLM). Gaining control of prime solar sites has become very competitive as many developers vie for the same prime locations. Companies that have filed the necessary paperwork with the BLM, requesting use of a particular tract of land, must work their way through a rigorous permitting process. Consequently, having the latest technology concept, or even a proven technology, does not necessarily translate into project success. Although land and an economically feasible technology are the fundamentals needed to build a utility scale solar project, there are many steps in the permitting and approval process that must be completed prior to a site being deemed "shovel-ready." The race to develop utility scale solar projects is being driven by state-mandated Renewable Portfolio Standards (RPS) requiring utilities to achieve a certain percentage of generation from renewables. The amount of electrical generation that must be achieved, and by when, varies from state to state. To reach these mandated goals, utilities are entering into power purchase agreements (PPAs) with renewable energy developers who commit to provide a certain amount of electrical generation within the timeframe outlined in the PPA. The process of negotiating a PPA can take up to 16 months. Achieving the scheduled inservice dates can prove extremely challenging. In an ideal world, the initial stages of developing a utility scale* solar project (ex. siting and permitting) takes 12 to 18 months to complete, with all permits in place before construction begins. The reality is that the initial stages can take 24 months or longer, depending on state regulations and the type of technology proposed. The following offers a broad glimpse into a complex process that varies from state to state and project to project, also providing a general description of the process on BLM lands. Siting process. Most utility scale solar projects start with a desktop siting study of potential solar sites to determine any fatal flaws. The siting study evaluates both physical and environmental criteria used to evaluate a site's potential as a solar project location. One of the most important factors is the amount of solar radiation available. Other physical criteria that are evaluated include the distance to the nearest point of interconnection and the need for transmission facility upgrades, as well as the distance to the nearest natural gas line, the availability of water, land ownership, site access, and topography. Environmental factors that are evaluated include the possible presence of endangered species, the presence of known cultural resources, the distance to Class I areas (including National Parks and National Monuments), and the presence of potential sensitive receptors (people and places). This initial due diligence analysis eliminates sites that present substantial challenges for successful solar project development. Critical Issues Analysis (CIA). After narrowing down the number of sites, a CIA is conducted to characterize the environmental and permitting risks associated with each site. A typical report contains recommendations for additional investigations to help assess potential environmental issues associated with site development. In some cases, an in-depth permit feasibility analysis may be included to facilitate risk management decisions and develop a permitting strategy that works for the developer and regulatory agencies. Agency coordination. For all utility scale solar projects, agency coordination is critical to a project's ultimate success. Agency involvement may include multiple federal, state, and local agencies (ex. BLM, state fish and game agencies, local county governments, etc.). The pre-filing process is a period prior to officially filing a project application, during which the developer meets and coordinates with appropriate agencies and key stakeholders regarding the proposed project. Since different timelines may exist for federal and state permitting processes, this period is vital for the developer to understand the regulatory agencies' requirements and timelines, and coordinate accordingly. Permitting. The permitting process begins with the developer submitting an application to the appropriate lead regulatory agency. The application includes a project description and describes the activities to be implemented to evaluate the potential environmental impacts of the project. This includes completing a preliminary geotechnical study to assess foundation requirements, a hydrogeologic study used to evaluate the current drainage patterns across the site, and various environmental field studies, some of which are described below. Field studies. Regardless of the state and type of technology implemented, one of the major challenges is the support of field studies. Field studies include, but are not limited to, biological resources, cultural resources, geotechnical investigation, hydrogeological testing, and visual resources. In general, field studies are labor intensive due to regulatory requirements and will often drive the permitting schedule. Project Timing. A typical timeline for the siting process may span several months to identify a site for development. Once a site is identified, the prefiling process may take from six to 12 months prior to formally submitting an application, at which point the permitting clock starts. Completion of the appropriate environmental evaluations may take from 12 to 24 months, which culminates with the issuance of necessary permits for construction. At this point, the project is considered "shovel-ready." One of the important pieces of the entire process is communication. Communication with federal, state, and local agencies is imperative. Just as important is communication with the public and stakeholders (ex. private landowners potentially affected). Communicating early and often with both agencies and the public allows the developer to identify any unforeseen issues that may be encountered during the formal application period. Communication should continue until completion of construction. Although complex, the initial project development stages are designed to involve regulatory agencies and key stakeholders, address potential environmental concerns, and provide an open and transparent process in developing a utility scale solar site for the benefit of many commercial and residential end-users. * In this article, utility scale solar indicates a solar project that intends to sells its output to a utility customer, as opposed to using the output for a direct use end-user. ~ Constance Farmer has over 30 years of experience, with a focus on licensing both commercial-scale alternative energy and traditional energy power projects, and permitting and construction compliance for large-scale electric transmission projects.

If so, then it is worth becoming familiar with a few items that will help ensure realistic expectations about the benefits of going solar. First things first... if thinking about installing solar on the roof of a building, please consider having a reliable roofing contractor inspect the conditions of the roof beforehand. The expected life of a typical solar system is 20 to 40 years. Rooftop problems (such as leaks) after solar Exhibition inter North America Conference and a solar system has been installed are not worth the risk--and this applies to both residential and commercial installations. The good news is that, once installed, solar panels will act as a barrier and provide a certain degree of protection to a roof from direct exposure to sunlight, hail, and snow. In terms of grid parity--the point at which photovoltaic (PV) electricity is equal to, or cheaper than, grid power-- is expected to be reached by 2015 in the US. But, like with everything else, there are a lot of variables affecting this date. The bottom line is that, until a solar PV system is paid off, expect to pay more for electricity. How much more? Well, there are so many variables involved it would be unfair to quote a general amount. Consider contacting a reputable solar PV system installer and requesting a quote. Keep in mind, there are many alternatives available for obtaining solar PV system financing, including rebates from local, state, and the federal government. As an example, after doing some research, a solar PV owner found that the monthly cost of obtaining a second mortgage to cover the cost of purchasing a solar system was less than the amount of his average monthly electric utility bill. Some more points to consider... System size. When calculated correctly, the size of a PV system should match the annual amount of electric energy consumed, expressed in kilowatt hours per year, for the specific electric meter for which a household is now paying electric utility bills. To install solar for a residence, the annual number of kilowatt hours consumed in the previous 12 month period will be the primary factor in determining the appropriate system size. Electric utility meters. Imagine owning a residence located on the family farm. Out in the corn field is a well used for watering crops. If interested in going solar for this residence and for powering the well, two different solar systems are required. The reason for this is because the well pump and the place of residence will be on two different electric meters. More importantly, the billing rates will be different. 400 EXHIBITORS | 15,000 VISITORS | 1,600 CONFERENCE ATTENDEES July 14 �16, 2009 San Francisco | California | Moscone Center PHOTOVOLTAICS | SOLAR THERMAL TECHNOLOGY | SOLAR ARCHITECTURE Co-located with w w w. i n t e r s o l a r. u s R E S E R V E Y O U R E X H I B I T I O N S P A C E T O D AY A N D S E C U R E A PLACE WITH THE INTERNATIONAL SOLAR INDUSTRY! 24 March / April 2009 nacleanenergy.com And, the last thing the utility will want to do (or is allowed to do) is to combine these rates. So, for every electric meter billed, a separate solar system is required. Going green. Once the decision to have a solar PV system installed either at home or work (or for a well pump, etc), choose a reputable solar installer. They will perform an energy audit for the residence and/or business facility, and provide a written report about how to improve energy efficiency. This report will include simple things, like using compact fluorescent lamps in place of incandescent lamps, or replacing T-12 fluorescent lamps using magnetic ballasts with T-8 fluorescent lamps using electronic ballasts. After reviewing this report, one might even decide to forego having a solar PV system installed and just make the energy efficiency improvements. Going solar. After a comprehensive look at going solar, research will show it is not only expensive but, from a holistic, whole-earth viewpoint, it is also not really "green" (because the manufacturing process of all things solar is inherently "dirty," as is the installation). The good news is that, once installed, solar offers one of the most dramatic and effective reductions to carbon footprints possible. As a citizen, living in the most energy intensive country on earth, one will do more for the environment by going solar than by any other means. (Granted, selling your car and walking to work will also have a big impact--and in a number of good ways...the planet, your health.) After a solar PV system is paid for, the cost savings is substantial. If the system is correctly sized, the only monthly payment to the utility is the charge they impose for "their" electric meter. As a consumer of electrical energy, there are always going to be costs associated with that consumption. Now, here is the primary reason for going solar: you will feel good! Buying solar is like purchasing a pair of shoes or a shiny new car. When all is paid and done for, the lower cost of electricity made possible by a solar PV system is well worth it, the appearance of all those solar panels on the roof looks quite attractive, and the neighbors are thoroughly impressed (especially when they see the equipment used to connect the solar system to the grid). Going solar is a smart investment in the way that a good education will last a lifetime. And, a solar PV system will help to bring the country one step closer to eliminating dependence on non-renewable resources. Early solar installer adopters viewed their bottom line as a function of "Profit, People, Planet." Today, these same business owners now realize that sustainability demands a paradigm shift to "Planet, People, Prosperity." Solar is one way to get there.

Utilities are using it to generate power, businesses use it to lower their peak energy demands, and eco-minded consumers are using it for their homes. When most people think of solar energy, their natural inclination is to picture large panels placed upon the roof of a building to generate electricity or to heat water. However, new technologies have brought about a revolution in the design and functionality of solar energy systems. One of the most interesting evolutions in photovoltaic (PV) or solar electricity generation application is Building Integrated Photovoltaics (BIPVs). In this type of application, solar electricity generation is built right into the building. By simultaneously serving as the building envelope material and a power generator, BIPV systems can provide savings in materials and electricity costs, reduce use of fossil fuels and emission of ozonedepleting gases, and add architectural interest to the building. BIPVs can take many forms, including the following... Thin-film is a type of PV application that uses different active materials than a typical solar module to interact with sunlight and generate electricity. These materials can be deposited on glass, metal, or plastic foundations. The film can be flexible and incorporated directly into building products. Although the energy conversion efficiency of these cells might be higher than traditional silicon, A overall applications today are generally less efficient. However, the potential applications can usually cover a larger area. Thin-film technologies offer a promise of lower future costs due to fewer requirements of active materials and energy in their production, at least when compared to thick-crystal products. Semi-transparent thin-film modules allow light to pass through cells, providing an opportunity to incorporate PV into glass windows. In this case, the windows of a building can provide insulation, lower UV penetration, and generate electricity at the same time. Just imagine the south facing walls of a large office building covered in glass, while invisibly generating electricity every day. Traditional solar cells are being placed on transparent panels, which can then be incorporated into awnings, atriums, skylights, and parking structures. These types of structures can provide diffused shade and protection from rain and snow while generating electricity. This application can be especially useful for larger structures, such as hotels and high-rise office buildings, which may have limited roof space but also large parking structures that could benefit from a cover over the top level. Even residential homes can benefit from incorporating traditional cells. The New American Home, for example, which was featured by the International Home Builders Association, incorporated panels into the building itself, providing a shaded patio next to the pool. As you can see in the photos, the solar panels fit right into the roof of the patio itself. Entire roofs are now being constructed using traditional solar modules, connected together in a way that creates a cohesive and unified structure. This eliminates the aesthetic disruption of traditional solar panels standing out against the roof background. It can also increase the amount of area that can be used to harvest solar energy on any given day. Roofing shingles that are coated in thinfilm materials can be built into a roof along with traditional shingles to provide a more consistent appearance. Each shingle would be a mini-generator and, connected together, the shingles create an electricity generating system. Many find this application more aesthetically pleasing than traditional panel designs and, since thin-film shingles can be designed in different colors, the potential for this type of technology is bound to become more popular. Blinds, shades, and shutters can be coated in thin-film to provide additional electricity generation while blocking sunlight. In many cases, the opening and closing of the blinds can be tied to solar exposure, creating an automatic solar-powered shading system that provides comfort and electricity at the same time. Using the sun to power our lives is limited only by our imagination. Incorporating the ability to generate electricity into our everyday lives through building designs is only the beginning. As technology advances, expect to see new and innovative uses of the nearly limitless energy of the sun to create electricity, heat our water, cool our buildings, and power our transportation.

"In future we will have to reckon with more and more storms like this," said Artur Deger, founder and managing director of DEGERenergie. "This is why it is so important to actively deal with the subject, rather than just waiting for something bad to happen. After all, there are currently new solar plants being put up everywhere." According to Deger, the problem begins with legislation: "Up to now, there have been no pertinent guidelines for erecting photovoltaic plants. It has not even been decided whether such a plant is to be classified as a building or a machine. Consequently, building permits are usually awarded without any structural engineering inspection." Artur Deger and his engineers spent a lot of time and money on developing a design tool that takes account of wind loads in different regions of the world. They have created a so-called design tool that planners and operators of solar plants can use to safeguard against storm damage--this means DEGERenergie is offering a standard of safety that is currently not even demanded by legislators or insurance companies. Tracking systems from DEGERenergie increase the energy yield of PV systems by up to 45%. A solar plant planer only has to enter three values: country, height above sea level, and the official wind load factor. The software reveals which DEGERtraker can be used in this region, and with how many solar modules for it to be appropriate and safe for installation. A safety reserve ensures that, as a rule, even peak gusts will not affect a plant installed according to these specifications. "The wind load strain on systems differs greatly depending on the region," explains Deger. "This fact is taken into account by our design tool. This makes DEGERenergie the first manufacturer to offer its customers genuine safety, and to ensure that its products remain durably operational and do not cause any damage."

"I have always enjoyed working with the latest laser technology as this often allows new processing regimes to be identified," said Dr Tony Hoult, general manager of the west coast operations and an industry veteran with over 22 years of hands-on laser applications experience, particularly in the field of fiber lasers. "Bringing these new lasers and process capabilities together will allow IPG to make this facility a unique Center of Expertise for advanced laser microprocessing," said Dr Hoult. "We will split our time between internally generated projects aimed at improving our understanding of fiber laser processing, processing customer samples, and providing feedback on the performance of the many new fiber laser products that are emerging from IPG Photonics."

The well-known real estate maxim has equal application to the siting of solar projects. Perhaps not the most exciting of topics in the hierarchy of such solar power complexities as tax equity and utility finance, siting is the first prerequisite and arguably the single most important aspect of any solar project. It is where every project begins and ends. It is the one part of any project that you cannot get wrong--or fix if you do. Controllers Have you discovered them yet? A key aspect of solar siting that is often underestimated or even overlooked in the planning stage is politics, a common theme among the multi-faceted obstacles that must be overcome to achieve successful solar siting. Land acquisition, transmission, water rights, environmental regulation and constraint, overlapping government and regulatory jurisdictions, and community support all require savvy and skillful navigation of the shoals of political seas. If all politics is local and all siting is local, it is not a gross overstatement to conclude that all siting is political. If so, then even the most economically viable projects will need to survive in a world where, at times at least, common sense may appear to be a random variable. Location of land and water It is no coincidence that the most abundant sources of US solar energy are located in the remote, arid regions of the American Southwest, a great deal of which is federal or Native American tribal land uniquely sensitive to political issues. This brings many solar power developers into contact with the Bureau of Land Management ("BLM") to both secure project approval and negotiate terms of the project site lease. The BLM, in turn, both applies federal standards, including compliance with the National Environmental Policy Act of 1969 ("NEPA"), and coordinates with other agencies having jurisdiction. While such coordination may substantially mitigate the competing interests of disparate agencies, the need remains to carefully assess and balance key political interests. In remote, desert areas, water is a special problem, for both solar technologies that require it and the related support and maintenance facilities. With such a scarce commodity, political competition for access can be especially fierce. Transmission Visit www.resol.com Benefit from 30 years� experience in solar thermal control technology US and s meets e nal cod ernatio int Remote locations also offer special challenges to transmission. How far is the nearest population center and how far is the nearest access to the power grid? Is the best solution integration with existing transmission facilities or parallel development of new ones? Invariably, whether by negotiation of access to construction and operating rights of way or competition for integrated access, solutions to the above will entail the politics of persuasion. Tribal interest firstname.lastname@example.org A particular and often overlooked focus of political concern is the interest of local Native American tribes on neighboring or adjacent desert land. 30 March / April 2009 nacleanenergy.com Often these tribes hold the key to local political support, not to mention potential access to project sites, transmission rights of way, and water rights of their own. Regulatory logjam eliminating some of the "corporate world stigma" perceived by some opponents of project development. The future Much like other alternative energy, solar development is subject to a maze of overlapping government and agency jurisdiction, and a multi-polar process of approval. Apart from the BLM on the federal level, for example, there is the Federal Energy Regulatory Commission ("FERC"), which has been delegated authority to regulate the market for interstate electricity. This authority has been the subject of modern-day "states rights" battles with the overlapping and competing jurisdiction of state and local power authorities. State and local jurisdictions governing approval of both the project and project siting frequently overlap. Approval by one may not assure approval by another and disparate political interests may prove an obstacle to uniform compliance with disparate standards. At the most local level is the permitting process requiring assessment of a conglomerate of local political interests, extending at the most micro-level to overturning homeowner association bans on solar projects for residential housing. It is not surprising that negotiating the regulatory approval and permitting process is one of the most daunting tasks of solar siting. Environmental schizophrenia Solar power remains the great untapped resource that, if and when effective solar storage becomes a reality, could literally fuel America. Exceptional savvy and skill are required to wind one's way through the maze of mirrors that is today's solar political and regulatory environment. Happily, energy needs and political winds favoring renewable energy have never been greater. Roger Rosendahl is a partner in the Corporate & Finance Department of Kaye Scholer LLP's Los Angeles office, where his practice focuses on corporate, finance, and securities transactions including energy and other natural resource transactions, mergers and acquisitions, and project finance. Kaye Scholer LLP www.kayescholer.com Perhaps the most politicized of all components of siting is the critical need to address environmental concerns, whether mandated at the federal, state, or local levels. It is well known that mixed feelings about solar energy give many environmentalists a headache. Some think it is an answer to clean energy and energy independence. Others think it is an expensive blight on the environment. Some think both. In fairness, part of this is a legacy of early wind power development, beginning back in the 80s, including early political enthusiasm, substantial subsidies and, eventually, large tracts of highly visible land strewn with inefficient or abandoned projects. Lessons have been learned and solar power enjoys the advantage of the newcomer, being at once the smallest (1%) of US power production and the fastest growing (30% increase in 2007). Both requisite standards (ex. NEPA) and mitigation measures are now clearer. Environmental approval techniques now include employing pro-renewable energy "Green Power" to counter the anti-development crowd, thereby Be energised ... � Automation � Quality � Customized � Reliable ... with holistic RADOX� SOLAR connectivity solutions.

His mandate calls for 10% of energy to come from renewable sources by the year 2012. The future is now, as the saying goes, and it is essential to alter our view as to how consumers use and utilize energy. Financing the Power of Green Dick.Rai@NationalCity.com 661-799-0440 Intellectual capital and industry expertise Delivering maximum value Promoting the adoption of renewable sources www.NC-4Energy.com In California, the sight of solar panels on a rooftop is not something new; among other things they are used to heat pools or provide domestic electricity. Wind farms, similarly, are far from uncommon. Anyone who drives over the Altamont Pass can see thousands of modern white windmills pumping kilowatts into the grid. Iowa and, in fact, the entire mid-west have seen alternative fuel production facilities come into existence near feedstocks, corn fields, or soybean farms. For some time now, scientists in the Bay Area have been developing new strains of algae, which are converted into biodiesel, butanol, or ethanol, and used as alternative fuels in vehicles or as substitutes for petroleumbased products. The city of San Francisco has contracted to develop a cogeneration facility to turn solid wastes into liquid, and restaurant grease into either fuel or yellow grease. These measures increase use of renewable energy and reduce dependency on oil, but they be able to meet its commitment, with current alternative energy projects (biomass, solar, wave, and wind) in planning or pre-operational phases. The reality is that on a utility scale, there are insufficient projects planned or in process to meet the mandates for renewable energy, at least in the state of California. The question of "how do we get there from here?" looms large for inventors, investors, project developers, and scientists. Along with the new products and systems being created come new challenges, both from an operational risk perspective and from a pure risk perspective. Insurance brokers in the alternative energy marketplace have their choice of several insurance carriers to provide broad coverage for traditional exposures (automobile, fire, general liability, and workers' compensation risks, etc), but when special issues related to these operations need to be addressed, this list significantly diminishes. Environmental and pollution liability repre- The new order of entrepreneurs and manufacturers may be no less knowledgeable about risk transfer, but may not be as aware of the risk transfer programs that are available or being developed. are only the beginning for an industry whose time has come. The Energy Policy Act of 1992 (EPAct) set ambitious goals for flex fuel vehicles, but there were no filling stations to pump E85, so those goals were not met. Fast forward to 2008, a time when you can rest assured that domestic auto manufacturers will be bound under their assistance program to produce flex fuel vehicles or alternatives to gasolinepowered cars. Once those vehicles are produced, where will they be able to fill up? According to the Department of Energy, California, there are a total of 19 E85 stations and 36 biodiesel stations for a state of 38 million. In California, utility companies must obtain 20% of their power from renewable resources by 2010. The California Solar Initiative calls for 3,000 MW of solar produced electricity by 2016. Utility company PG&E has had its latest proposal for a traditional power plant construction project delayed due to its inability to demonstrate that it will sent two areas that are increasingly becoming difficult or expensive to transfer from the renewable energy provider to an insurer. Manufacturing a combustible material in a closed environment is nothing new. Oil and gas companies have been cracking hydrocarbons in their catalytic processes for centuries to turn fossils into fuels. A new generation of manufacturers is working on new organisms, with better technology, reduced cycle times, and modern day synthesis capabilities. But, at the end of the production day, they are creating a highly volatile potential pollutant for use in a combustible system. When an alternative fuel is manufactured at scale, it means millions of barrels per year. Petrobras in Bazil has a facility that will yield 15 million barrels of cellulosic ethanol per year, for example. When that fuel is manufactured, it still needs to find its way into the fuel delivery system. There are no infrastructures, pipes, or transportation facilities to get it to the refinery where it needs to be blended. 36 March / April 2009 nacleanenergy.com In October 2008, in the Bay Area a tanker truck overturned and it melted portions of Interstate 880 in Oakland, not an untraditional exposure, but one that will be ever-increasing as these new facilities come on line and ship their product to other facilities. To someone in the traditional world of manufacturing gasoline from oil, it is understood that these hazards exist. Additionally, they understand the immediate exposures, like a truck fire or long-term exposures and liability for underground storage tanks created by their businesses, and they are experts at understanding the risks they will retain or transfer. The new order of entrepreneurs and manufacturers may be no less knowledgeable about risk transfer, but may not be as aware of the risk transfer programs that are available or being developed. The risk transfer methodology deployed needs to be specific to the needs of each renewable energy company. The application in a solar company is different than that of a wind energy producer, which is different still for a fuel manufacturer. New products are available or being created that will allow a renewable energy company to transfer several liabilities, such as carbon credits, efficacy, tax, and warranty to enumerate a few. The level of retention or transfer is left for the individual company to decide. A start-up or Series A round company may elect to deploy their capital differently than a more mature, Series B, private equity funded, or public company. For instance, there are some relevant examples to be found in the solar power supplier domain. Solar providers have statistical data on `sun days' and projections of throughput to the grid--if there are fewer days, there are penalties and sometimes other consequences. The right exclusive risk transfer solutions can fund those exposures via an insurance policy, in a financial transaction that shifts potential consequence from the purchaser to an insurer. Transfer protocols have been negotiated to not only transfer warranty risk from the balance sheet, something that is an industry standard for all manufacturers of solar collection apparatus. Some terms, customarily five- to 20-year warranties are required of the solar cell manufacturer, representing the performance of their installed units. As a consequence, they are obliged to maintain that as a liability on their balance sheet, since the possibility of having a purchaser draw down on that facility exists in the event of a failure or lack of performance to some specified criteria set forth in the purchase agreement. When making the return on investment decision, the issue of "surviving the catastrophe" also needs to be a factor in the equation. In today's economic environment, it is imperative that a company explore every possible avenue in finding ways to enhance the terms of any project or deal; fuel manufacturing plant, utility scale solar, or wind development. Project financing is increasingly reliant on ever-diminishing margins and key deliverables from power providers and purchasers, as specified in the terms of power purchase agreements or fuel delivery contracts. The risk transfer initiatives employed should seek to smooth the curve, and effectively eliminate risk in a portion of the alternative energy provider's operations. Michael J La Fleur, CPCU, AIS is vice president of Hays Company of California. He works collaboratively with insurance companies and professionals in the field of renewable energy to develop programs for risk transfer through both avant-garde and established methodologies. Hays Companies www.hayscompanies.com How do we make no difference? New technologies help make the entire energy business more environmentally compatible than ever before.

AEGIS SGR Bearing Protection Rings from Electro Static Technology make this possible by extending the lives of motors controlled by variable frequency drives (VFDs). Although VFDs deliver energy savings (up to 30% or more), they also induce harmful currents on the shafts of the motors they control. These currents too often damage motor bearings, and lead to downtime and premature motor failures. Without an effective means of shaft grounding, the currents will discharge through the bearings, causing pitting and fluting damage to the bearing race walls. Over time, this can lead to noise, vibration, and bearing failure, reducing the reliability of a system and wiping out any savings from using the VFD. The AEGIS SGR shaft grounding ring channels harmful VFD-induced shaft currents safely to ground. Unlike conventional grounding brushes, SGR is maintenance-free and works with virtually no friction or wear for the service life of the motor. Because it comes in halves, the SGR ring can be installed in the field without disconnecting the motor from coupled equipment.

Dickstein Shapiro LLP | www.dicksteinshapiro.com/energy www.schleifring.com Non-contacting transmission Multi-Megawatt Design Standard Design Compact Design Revolutionary transmission technologies for WPPs The proportion of wind energy in the grid is increasing steadily. The sphere of wind power application requires an unparalleled level of precision and technical reliability. Particularly the rotating couplers are a key factor in the quality of the overall system. Develop approaches to identify client needs: Approaching the wind power specific demands SCHLEIFRING offers standard technologies, which along with versatile transmission variations allow absolute reliable performance even under extreme temperature changes, shock and vibration. The increasing share of wind energy claims the timely involvement of the off-shore utilisation. The reliability of these wind power plants presents a great challenge. In the latest 5-MW offshore wind turbine generation a compact and extremely rugged encoder integrated slip ring system made by SCHLEIFRING serves as essential device for the transmission of power as well as electrical signals and data for the control of the overall rotor package. In particular the power supply of 250 A for the pitch drive meant a very special challenge due to the extremely limited installation space. A salt spray resistant design along with a special ring and contact configuration allows long life and backs up an undisturbed opera-tion of the wind turbine even under extreme environmental conditions like shock, vibration and change of temperature from -40�C to +50�C. New slip ring technologies and their advantage for the wind power industry: SCHLEIFRING was instantly responsive to the wind turbine manufacturer's demand for longer lifetime. By optimizing special material configurations the latest generation of slip ring assemblies allows excellent operating life of >100 Mio. rotations. An integrated EtherCAP module faciliates the transmission of Fast- and Gigabit Ethernet data. An additional multiplexer even allows the transmission of any common bus system across this Ethernet interface. Although predominantly wind turbine slip rings utilizing precious metal sliding contact technology, SCHLEIFRING exclusively offers non-contacting transmission technologies for both power and data transmission, including all common bus systems up to Gigabit Ethernet and EtherCAT. A classic example: transmisson of low power (e.g. 1.5 kW) for hydraulic pitch drive systems plus Ethernet data. Along with capacitive systems SCHLEIFRING provides active optical rotary joints. The active rotary joint unit facilitates each data format and data protocol and may even be used for analog transmission and is suitable for the currently fastest common transmission components. Advantages of non-contacting technologies: wear-resistance, high noise immunity combined with excellent EMC performance, high reliability and bit error rates of <10 -13.

In this event, slip clutches protect the costly gearbox against overload by slipping at a defined maximum torque to temporarily interrupt the drive. The slip process takes place not on the generator shaft surface, but inside the CENTA Torque Hub, which is mounted on the generator shaft in the coupling's clamping set. CENTA's latest development in slip systems, CENTA Torque Set, now positions the slip unit to the middle section of the shaft. By relocating the slip function, manufacturing tolerances at the generator shaft no longer cause variations in the slip torque, resulting in improved accuracy of the slip function. Another advantage of the new design is the slip system is made to be premounted as a complete unit. The maximum torque is set on a certified test bench according to the manufacturer's requirements and documented in a test report, eliminating the need for on-site adjustments. The low-maintenance slip system is also designed to allow for multiple slip processes (> 200) without having a major impact on the slip torque setting. The new slip system can also be provided as a low-cost system component which does not include the coupling unit.

The January/February issue of North American Clean Energy contained an article focused on development costs--the costs to get a plant sited, constructed, and put on line. This article described four stages, which impact the costs and include: 1. Exploration and resource assessment 2. Well drilling and development 3. Power plant, surface facilities, and transmission construction 4. Other activities related to development The economics of these stages added up to an estimated $4000/kW. The GRC has determined that the price a geothermal power plant developer can offer to a utility in a Power Purchase Agreement (PPA) largely depends on the above four stages, as well as three other factors discussed below: 5. Financing charges 6. Operation and Maintenance (O&M) costs 7. Resource credits Financing charges Financing charges are mainly affected by the amount of upfront capital needed to cover the first two development stages: exploration and resource assessment, and well drilling and development. They are also affected by the timeline of these two stages, as well as the loan terms that allow a developer to repay the upfront costs and finance the remaining development stages. These costs are generally not financed by utilities, banks, or other lending institutions, but rather by venture and equity capital or in-house reserves. A high return, typically 15% to 25%, is needed to cover the high risk associated with these two development stages. Investors correctly interpret geothermal investments as high risk due to historical delays in getting projects sited, developed, and on line. For example, exploration at the Glass Mountain Known Geothermal Resource Area in Northern California began over 20 years ago--and there is still no power plant located there. For the purposes of discussion, a weighted average return of 18% is assumed over a four-year period. Different types of utilities and lending institutions have varying interest rates and terms. For instance, a developer can compare two scenarios: 10% and 15 years (representing bank financing), and 6% and 30 years (representing utility financing). Each scenario assumes the plant life is the same as the loan term, and there is no salvage value to the plant afterwards. Zero salvage value may be a harsh assumption; however, in 15 years, technology may have advanced to where the existing plant would need significant upgrading to take advantage of any higher conversion efficiencies that arise. If these two scenarios cover the boundaries of reality, a developer would expect to pay $48 to $87 per mWhr for the project financing, assuming a 92% plant factor. O&M costs Resource credits Geothermal power and other renewable resources may use rapid depreciation or other incentives, such as the Production Tax Credit (PTC) and Renewable Energy Credits (REC), to reduce final costs to supply the output to the market. Other incentives, such as pollution credits, may apply in the future. The bottom line Fuel costs for geothermal power plants are insignificant. These expenses are costs for steam field management and geothermal fluid impacts on equipment. These costs are covered in the power plant design expenses, as well as in operation and maintenance costs. O&M costs include those charges for employment salary and benefits, equipment replacement reserves, utilities, and administration. Most of the new geothermal power plants coming on line are going to be closed-loop, air-cooled, binary cycle plants. These O&M costs are assumed to be lower than the typical plant, and at a level of about $15 per mWhr. 64 March / April 2009 nacleanenergy.com Taking into consideration the development, financing, and O&M costs, a typical geothermal developer can expect to charge a utility $63 to $102 per mWhr for the plant output, excluding any reduction due to resource credits. Charges could fall outside this range, or higher, due to several factors. One factor is the local, regional, national, and global competition for commodities such as steel, cement, and construction equipment. Another factor is the ability to lay out a realistic project schedule and then meet it. Any project delays are costly, especially on the front end as the first two development stages have a higher rate of return on investment than the next two stages. The GRC recognizes that more projects will come on line and within budget if adequate time and effort is spent on using reliable developers and technologies, assessing the adequacy of the geothermal field, managing the field, meeting permit and regulatory schedules and requirements, and acquiring reliable PPAs and transmission paths. Guy Nelson is the team lead of the Utility Geothermal Working Group, which provides energy education and training for utilities.

They often require the Solar PV system to be fully operational for several decades before it can yield the desired return on investment. CITEL manufactures surge protective devices (SPDs) for tures e (SPDs Photovoltaic applications. SPDs that protect the AC main SP di t ib ti panel, inverter, charge controller & PV combiner l i t h distribution box against over voltages originating from the AC utility, industrial switching machinery & lightning strikes. In the past, many manufacturers would guarantee a system life of greater than 20 years. All costs and investments were calculated based on this time period. However, many systems are not reaching maturity due to the nature of this exposed application to the lightning phenomena and its interconnection back into the utility AC power grid. For this reason, it is prudent to invest in surge protection to eliminate these potential threats and thus maximize the systems life expectancy. ST�UBLI GROUP Lake Michigan Wind & Sun, Ltd. has added a new design to its Solar Flairs line of PV sculptures. Solar Flairs are arrays of solar panels arranged in configurations that mimic the symmetry of nature. The newest design, the SF 1152, resembles an eight-petaled flower. It is mounted on a free-standing mast and is either fixed at an optimal angle to the sun, or equipped with dual-axis tracking that allows it to follow the sun's path across the sky, dramatically increasing the system's productivity. One SF 1152 can satisfy the energy requirements of a small office or classroom. Several of these units in a group increase their impact both visually and in terms of electrical output. The efficiency of Solar Flairs is equal, square foot by square foot, to that of standard solar systems, but Solar Flairs offer an alternative to the blocky rectangular appearance of traditional freestanding arrays. Their design allows them to better assimilate into the landscape, making them ideal for gardens and landscaped grounds. Their purpose is twofold: to provide onsite generation of electricity, and to make a visual, artistic, environmental statement. Municipalities, corporations, and institutions which are seeking a greener reputation are likely entities to consider "planting" Solar Flairs at their facilities.

Today's growing focus on ocean renewable energy development is reflected in the 50 wave and tidal power projects that have already been proposed to the US Federal Energy Regulatory Commission. These projects all require the same thing: the latest high-tech seabed mapping techniques to pinpoint the best sites for wave and tidal power generators. Issues such as seabed depth, wind, and wave conditions, navigation lanes, whale migration routes, and environmental impact all need to be considered. Mapping the seabed involves sending hydrographic survey ships and smaller boats out to sea equipped with sonar systems, which send sound waves that bounce up to the ship from the bottom of the ocean. The sound waves find and identify objects in the water. Data is then digitally collected, processed, and stored with specialized computer systems that generate graphic displays. "Our knowledge of the seabed is incredibly limited; the charts that exist were prepared using basic echosounders," says Burt Hamner, chair of the Marine Technology Society's Renewable Energy Committee. "All we know is how deep it is, with very little knowledge of what the seabed condition is." Over the past 20 years, technology for seabed mapping has become incredibly advanced, says Dr Mitchell Roffer, whose Florida-based company provides oceanographic consulting services worldwide. "They're mapping from satellites in planes looking down, looking at the surface with drifting buoys and acoustic systems to measure the currents, and looking up from the bottom using submersibles or cables left on the bottom. It's a three-dimensional mapping effort." High-resolution side scan sonar enables hydrographers on the surface of the ocean to observe a big swath of the seabed in real time, so they can learn about bottom conditions, hazards and habitats, adds Hamner. "The sonar resolution is good enough to identify an object the size of a chair on the seabed bottom from three or four miles away. It's also able to characterize the type of seabed, such as sand or gravel or mud, and then portray all of the information in 3D colored maps." Unmanned, undersea gliders are another exciting development, says Roffer. "They're very quiet, and require very little energy; they actually come up to the surface, release their data streams and then go back down. They can operate for weeks in very shallow water or very deep water." Many of these cutting-edge techniques are widely used across Europe, Hamner adds. "When people start realizing that the technology to develop offshore energy really exists, they become quite excited about it." But high-resolution surveys are extremely expensive. "To survey a significant chunk of seabed to find a precise spot for a wave energy device can cost millions of dollars," notes Hamner. "As a consequence, most coastal states have done very limited seabed mapping using these technologies." The National Oceanic and Atmospheric Administration, which is responsible for charting roughly 3.4 million square nautical miles of US navigable waters, performs about 80 hydrographic surveys each year. "Seabed mapping data is important to a lot of communities, including offshore renewable energy, and there is a growing demand for this type of data, but there is only so much capacity within the federal mapping agencies, primarily NOAA, to meet all of these needs," reports Roger Parsons, NOAA's Integrated Ocean and Coastal Mapping Coordinator. That's why Hamner is circulating an online petition, asking Department of Energy to recognize seabed mapping as critical for ocean energy development, and to fund offshore hydrographic surveys. "There is no way ocean renewable energy can be developed without ocean survey data, and no private company can afford to do it," says Hamner. "It's a great time for the Department of Energy to stimulate ocean energy development, and create `green' jobs on the waterfront and at sea right now by mobilizing the survey ships and local fishing boats, because they're ready to go." Hamner reports that meetings between the Department of Energy, NOAA, and the coastal states are in the works to "help everybody understand why this is a good, integrated solution. It's in the interest of the energy industry to actively promote and support NOAA and the coastal states. Managed together, this is the largest renewable energy project in the USA."

Under the ecoENERGY for Renewable Power program, the East Toba River and Montrose Creek Hydroelectric Project will receive a $10 per MWh incentive over the first ten years of operations, in accordance with the terms of the agreement. Net annual electrical generation from the Project is expected to be 726.95 Gwh per year. Payments will commence once the Project is commissioned, which is on schedule for completion in mid 2010. "The development of clean, renewable energy projects is instrumental in achieving both federal and provincial governments' initiatives on climate change, and federal support through programs like ecoENERGY are important to the industry's success," said Plutonic Power vice-chair and CEO Donald McInnes. Once completed, the East Toba River and Montrose Creek Hydroelectric Project, a partnership with GE Energy Financial Services, will potentially displace an estimated 455,000 tonnes of greenhouse gases (GHG) annually. This is the equivalent of taking about 80,000 cars off the road per year or planting about 60,000 hectares of trees. With an estimated capital cost of $660 million, this 196 MW project has been under construction since July 2007 and is on budget and on schedule for commercial operation by mid 2010.

Methane is generated by the anaerobic degradation of organic materials in municipality solid waste, and is 21 times more damaging to the environment as a "greenhouse gas" than carbon dioxide. Many landfills are emitting methane directly into the atmosphere without flaring. This is upsetting the surrounding communities and environmental groups who are demanding this practice cease. Some of the landfills are reducing the damage by flaring the gas--burning it to convert methane to heat and carbon dioxide. The heat is typically wasted. Since the methane content of landfill gas is low (30% to 55%), it is very difficult for landfills to use this potentially valuable source of energy to generate revenues for themselves. Power generation equipment on site typically requires extensive pre-treatment of the gas and wastes 75% or more of the energy as heat, since a landfill currently does not have much use for thermal energy. The combination of pre-treatment costs and low efficiency of electricity generation equipment produces very small revenue streams. For those landfills situated close to natural gas pipelines, it is possible to feed the purified gas into the pipeline. The purification costs, once again, combined with compression costs, make it a fairly unattractive financial proposition. The environmental damage from landfills could be avoided if landfills were given a profitable way to abate the methane, justifying the capital costs of extensive equipment required on closed, non-operating landfills. A new approach to sequestering carbon from landfill gas has been designed and is about to be piloted in San Diego County, California. This process uses a patented A catalyst, which cracks methane gas (a major component of natural gas and bio gas), into its elemental constituents, carbon and hydrogen. The catalyst was originally developed to produce highly organized platelets of graphite from natural gas. The graphite is further treated to manufacture Platelet Graphite Nanofibers, an extremely valuable nanomaterial with vast possibilities in materials performance enhancement. Graphite produced from the landfill gas will be sold to a wide variety of industries that use it, such as the aerospace, automobile, manufacturing, steel, and chemical industries. In the past, methane cracking to sequester carbon has not been a viable process because of the low value soot produced as the carbon product. Additionally, such processes would generate other undesirable byproducts, such as carbon monoxide. However, the new sequestra- tion process will generate high-quality graphite and hydrogen from the methane source--with no additional byproducts. A pilot facility, which will take a small side stream of the landfill gas and produce graphite and hydrogen, is expected to be operating in the next few weeks. The complete processing plant will use conventional techniques, such as vacuum swing absorption, to purify landfill gas, and then utilize the technology to produce a precursor material (high-quality graphite) for high value nano powders. This approach helps landfills eliminate the need for flaring the methane, or obtaining extensive permitting for air quality emissions required for electric turbines/internal combustion engines. Additionally, producing a higher value product will enable the technology owners to compensate the landfills better than current projects. As a potential added bonus, this type of landfill methane processing could be a source for medium-scale urban production of hydrogen. By nature, the hydrogen would have a zero carbon footprint, and could address environmentalists' concern about the Life Cycle Analysis (LCA) Green House Gas Effect of current hydrogen production technologies. The hydrogen produced at the landfill site could also be utilized to power fuel cells at the landfill site and feed green energy into the power grid.

"Wastewater treatment plants, if they take an aggressive approach, cannot only do more to increase self-reliance, but they can offer a direct solution to our dependence on foreign fossil fuels," said David Parry, vice president of Camp Dresser and McKee, a consultant, engineering, construction, and operations firm, in a recent article in WEFTEC. Here's where the fight gets interesting: in the battle over food waste, at some point the question of how to best collect and deliver food waste must be considered. The two basic options are: 1) collecting it for delivery in trucks to a biogas facility; and, 2) using food waste disposers to pulverize food scraps into a liquid slurry for transport via underground sewers. In fact, disposers have served that purpose for more than 50 years in the US, and are rapidly growing in international acceptance, especially in regions and countries where restrictions on the landfilling of organic waste are being imposed. In the States, an estimated 60 million residential and, perhaps, 500,000 commercial food waste disposers are in daily use, diverting millions of tons of food scraps from garbage trucks and landfills. Instead, those scraps--averaging 70% water--are ground and flushed to wastewater treatment plants. Yet disposers are often overlooked and misunderstood for the essential role they play, given their common presence in North American homes. Stockholm is an excellent example of the more conscious view of disposers that is rapidly developing. In 2008, Stockholm's Water Board reviewed a comprehensive report on the use of disposers and decided to remove both its surcharges on disposers and any geographic restrictions on their use. Stockholm's concern? Increasing production of biogas, on which Stockholm relies to fuel its bus fleets, was a significant impetus. However, the study confirmed that disposers could be used without concern while helping Stockholm achieve its goal of diverting 35% of its food waste. In the UK, Worcestershire County's "Sink Your Waste" initiative is directly subsidizing disposer installation as the preferred alternative to curbside collection. In the US, a study conducted by the East Bay Municipal Utility District in Oakland, California, with support from EPA's Region 9, confirmed that food waste can boost biogas production by as much as 20%. EBMUD's study also found that more than 120 anaerobic digesters at California's wastewater treatment plants had excess capacity of 20% or more, suggesting the opportunity to take in additional material for biogas production. Last year, the San Antonio Water System announced a 20-year deal with Ameresco to boost its production, collection, and beneficial use of biogas, projecting $250,000 in annual revenue. Stockholm's enlightened thinking, and San Antonio's public-private partnership establish important precedents that will stimulate broader consideration of the role of wastewater treatment plants as generators of energy, and spur consideration of their compelling role in handling the challenge of food waste for municipalities searching for environmentally sound answers. Kendall Christiansen is senior consultant on environmental affairs with Insinkerator, manufacturer of residential and commercial food waste disposers. Camp Dresser | www.cdm.com Insinkerator | www.insinkerator.com t some point in the coming decade, food fights will break out--but not in school cafeterias. Instead, the fight will be over food waste generated by a variety of sources. The fight will be waged between wastewater treatment plants anxious to boost biogas production in their anaerobic digesters, operators of various biogas technologies financed by subsidies for renewable fuels, and compost facilities that need feedstocks to make products that replenish our soils (and replace petro-based fertilizers). But sometimes the weapon of choice is right in front of us, hidden in plain sight--under the kitchen sink. That weapon is the food waste disposer (i.e. disposal or garburator), a device that begins the process of converting food scraps into energy and fertilizer products. Already thousands of biogas/biomass facilities operate in the relatively mature EU market, leading the pressure to expand into North America. In the US, over 500 wastewater treatment plants (mostly large ones) operate anaerobic digesters, using their heat and biogas to operate the facilities. The emerging energy crisis is A UK paves the way for energy recovery from biomass and waste "Landfill is the worst environmental option" According to the UK Waste Strategy landfilling waste is the worst environmental option. The methane it produces is a potent greenhouse gas, 21 times more potent than carbon dioxide. Consequently, the Landfill Directive calls for a 50% reduction of the biodegradable municipal waste that is dumped at increasing costs. Energy recovery from biomass and waste is going to play an important role in this scenario. The Waste Strategy encourages a variety of energy recovery technologies including anaerobic digestion for biogas production and mechanical-biological treatment, which can produce refuse-derived fuels. Energy from waste is expected to account for 25% of municipal waste by 2020, compared to 10%. This creates a need for new infrastructure. Estimates vary between 100 and 500 new operational plants that are required to deal with the United Kingdom's residual waste. "Using waste as a resource for energy and materials recovery makes total sense," explains Dr Ines Freesen, managing director of the Energy from Biomass and Waste UK (EBW UK) Conference and Exhibition. "Not only is it beneficial to the environment, it also helps the public and private sector to cut costs dramatically." The steadily increasing landfill tax makes waste disposal a costly exercise in the UK.

The company supplies both mobile processing reactors and fully processed biodiesel fuel--which offer a new option for individuals, businesses, entrepreneurs, and local communities to become fuel manufacturers and produce ASTM grade biodiesel at approximately $1.24 per gallon, opening a new market of legal Turning waste oil to biodiesel biodiesel production in the 250,000 gallon per year range. According to recent surveys, almost two-thirds of Americans are interested in making "greener" choices, including making the switch from gasoline or diesel to more environmentally friendly forms of fuel. Unfortunately, opportunities in the alternative fuel market have been quite limited. As a producer of high-grade biodiesel fuel (manufactured from common vegetable oil or animal fats), PNE decided to provide the opportunity for other innovators to produce their own biodiesel fuel onsite for business uses. The company offers an efficient and functional mobile biodiesel processing unit that is available anywhere in North America, and that can exceed ASTM quality standards. These processors are self-contained and come installed in one standard 20 x 40-foot cargo container. The containers can be easily transported and set up anywhere that the materials in the supply chain dictate. By introducing highly mobile units, PNE will overcome many of the problems conventionally associated with biodiesel production, including the cost. Now the manufacturing plant can go to the supply in many cases, reducing transportation costs, and the need to order fuel far in advance. The PNE business model allows for a new mid-range of biodiesel production. Restaurant chains, governmental bodies, and entrepreneurs can service their own fleets of trucks, vans, or sell biodiesel at a profit. Pacific Natural Energy www.stopxon.com Engineers at large food/beverage industry operations, which are harvesting their bio-waste in fermentors or digesters to generate heat or power and reduce pollution, will find the ST98 Biogas Flow Meter from Fluid Components International (FCI) provides precise measurement of these wet, dirty, mixed methane composition gases. On dairy farms, for example, large amounts of cow manure accumulate that are a rich source of biogas, which can be harnessed for the eco-friendly production of green electric power. The output from the manure biomass digestion process results in a complex gas mixture that includes methane (CH4), carbon dioxide (CO2), water, and trace amounts of hydrogen sulfide (H2S). This biomass production process requires optimizing gas creation, cleansing, drying, and storage (tank or bag-type accumulator) to use the biogas as a fuel source for heating or powering a co-gen engine to produce electricity. Biogas flow must be measured at several points in the system to provide operators with critical information for optimal gas production, control, and reporting. A ground flare is an integral part of the safety system for the process. Mass flow measurement of biogas is challenging. This gas is typically 65% CH4 and 35% CO2. Biogas is dirty and corrosive with particulates that will quickly clog any flow meter designed with orifices, and it will foul meters with moving parts. Low flow measurement sensitivity and a wide turndown are essential due to biogas flow variability, based on biomass supply and environmental fluctuations. With its reliable thermal mass sensing element, the advanced ST98 Mass Flow Meter from FCI delivers precision gas flow rate, totalized flow, and temperature measurement. It is ideal for biogas measurement and features high accuracy to �1% of reading, 0.5% of full scale. ST98 further offers repeatability to �0.5% of reading and is temperature-compensated for accurate measurement under variable environments. The insertion style ST98 Flow Meter operates over a wide flow range from 0.75 to 600 SFPS (0.21 to 172 NMPS). It features a turndown ratio that is factory preset from 10:1 up to 100:1 within the calibrated flow range and operates at pressures up to 250 psig [17 bar (g)].

For technologies like the electro-reduction of carbon dioxide (ERC), cross-disiplinary collaborations like these can transform blue sky ideas into commercially viable products. he world is waiting with urgency to see if carbon capture and storage projects are feasible on a large scale. On January 28th, 2009, the European Union invested in that possibility by approving a 1.25bn ($US 1.6bn) financing package for carbon capture and storage projects (CCS). Carbon capture and storage describes a broad set of technologies that will recover carbon dioxide from industrial or energy related point sources and store it in deep geological formations, in ocean reservoirs or as mineral carbonates. Four years ago, the Intergovernmental Panel on Climate Change estimated that by 2100, CCS projects could potentially lower annual global CO2 emissions by 55%. They also stated that if successful, the global CCS market value is expected to increase to over $US 236bn by 2012, a compounded annual growth rate of 22%. So far, however, there has yet to be a full-scale industrial CCS project that links the processes of CO2 capture, transport, and storage because for the most part, the costs still outweigh the global perception of the consequences of climate change. At a minimum, the average cost of an industrial CCS program is $US 80 per metric ton of sequestered CO2. With world carbon dioxide emissions projected at 37 billion metric tons per year by 2020, that creates a rather big dilemma as to what to do with the potentially massive amounts of gas that may be captured. Questions are also being raised about the unknown environmental risks of storing large quantities of CO2 underground. As currently envisaged, carbon capture and storage projects will add costs to industrial processes without generating any revenue. An alternative to burying the `waste' CO2 is to convert some of the captured CO2 into valuable fuels or chemicals. Treating CO2 as a commodity would substantially offset the costs of carbon capture. There are several ways to convert CO2 including thermochemical, biological, electrochemical, and photochemical processes. To become commercially viable, however, the processes need to be technically efficient, economically feasible and have established a potential market for their products. Research at a variety of institutions is underway in response to this challenge. One technology showing potential is the electro-reduction of carbon dioxide (ERC). Initiated at the University of British Columbia in Canada, the ERC aims to take CO2 directly from industrial waste gases and convert it to formate salts and/or formic acid, both valuable chemicals. Several potential markets for the products of the ERC have been established. Formic acid can be used in a variety of industrial applications, such as steel pickling, to replace mineral acids, improve the finished product and alleviate the problems of effluent disposal. The organic acid also has the potential to play a leading role in fuel cell development, both as a direct fuel and as a fuel storage material for on-demand release of hydrogen. One of the challenges remaining for the ERC is to find a cost-effective way to obtain highly concentrated CO2, necessary for technical efficiency and economic feasibility. The answer to this challenge may have been found in the small German town of Spremberg. In Spremberg, beside the old coal-fired power station of Shwarze Pumpe, the Swedish power group Vattenfall has built a 30 megawatt (MW) CCS pilot plant to deliver concentrated CO2 directly from the flue gas. Relying on oxy-fuel technology, the plant burns coal with pure oxygen rather than in air. Whereas conventional air combustion gives a flue gas with 10 to 15% CO2, oxy-fuel increases the concentration of CO2 emitted to better than 90%. The directive of the Vattenfall project is to link the full chain of CO2 capture, transport, and storage with near zero net emissions. As CCS projects need high concentrations of CO2 before the gas can be liquefied, transported, and stored, the Shwarze Pumpe project has eliminated the costly and energy intensive post-capture process of CO2 concentration. Apart from thermal power stations, oxy-fuel can also be used to boost the CO2 content of flue gases in a wide spectrum of industrial processes, including cement manufacture, glass making, and iron and steel production. The outlook is bright for Vattenfall, as the first tonnes of CO2 captured at Shwarze Pumpe had a purity of 99.7vol%. The company has further plans to build a 3000 MW lignite-fired power station based on oxy-fuel in 2015 in Janschwalde, Germany. Praxair, 82 March / April 2009 nacleanenergy.com T a second company involved in oxyfuel, is also developing a 50 MW coal-fired electric pilot plant in Jamestown, New York. Oxy-fuel at the industrial scale will allow the ERC and similar CO2 conversion processes to achieve a higher intensity of reaction and use smaller reaction surfaces. The translation for investors is lower capital and operating costs. Carbon conversion technologies like the ERC, used in combination with oxy-fuel, may provide an economic incentive for industry to take the next step toward emission reductions. As the climate crisis continues, connecting the intelligence of science, the foresight of business, the know-how of industry, and the political will of government will be the key to environmental protection. The future of climate mitigation efforts will depend on the ability for all partners to communicate and collaborate on ideas and initiatives. Venture companies and clean tech business entrepreneurs, in particular, play an important role as translators. They bridge the gap between science and investment by investigating opportunities and connecting research partners, contributors, and licensees. Most likely the answer to climate change will not be a single silver bullet, but will involve a variety of solutions. The attractiveness of climate change mitigation options will depend on our ability to link innovations and create a set of commercially viable products. With the scientific knowledge available to us, the key will be putting the pieces together. Larry Kristof is chief executive officer of Mantra Venture Group, a venture company facilitating investment in sustainable, commercially viable clean technologies. The ERC technology is now owned by Mantra Energy, a subsidiary. Mantra Energy Alternatives Ltd. | www.mantraenergy.com Schroeder BioFuels has introduced its EWU unit for purification of biodiesel fuel. Each treatment tower holds 50kg (or 110 lbs) of Eco2Pure media, increasing the amount of time between media changes. EWU is designed for industrial use and features a continuous flow with a connection arrangement that allows for simple, online, treatment tower recharging. The unit is designed to filter fatty acid methyl/ethyl ester fluids (crude biodiesel that has already had the glycerin and methanol removed), and is equipped with Schroeder's own TCM laser particle monitor for measuring particle contamination. The towers use Eco2Pure media to remove soap, production residues, and contaminants from biodiesel. Schroeder Biofuels can design, build, and commission a purification system to suit specific needs of biodiesel producers. Schroeder BioFuels | www.schroederbiofuels.com Purification of biodiesel biomass and biofuels news briefs Recommendation on biomass harvesting Volatile oil prices, concerns about carbon dioxide emissions, and catastrophic wildfires have created new interest in removing wood from forests as an alternative energy resource. In response, states from Maine to Missouri are developing guidelines for the harvest of forest biomass-- logging slash, small-diameter trees, tops, limbs, or small trees. A report by the Forest Guild, entitled "An Assessment of Biomass Harvesting Guidelines," is the first comprehensive review of these biomass harvesting guidelines. The report provides recommendations to ensure that new guidelines promote sustainable use of biomass from forests. "New interest in woody biomass is a double-edged sword," says Dr Zander Evans, Forest Guild research director and the report's author. "If harvested sustainably, biomass can meet some of our energy needs and leave our forests healthier than they are now. However, without appropriate guidance, biomass harvests can seriously degrade our forests." Forest harvesting guidelines provide foresters and loggers advice on how to remove woody biomass and how much should be left in the woods for healthy watersheds, wildlife habitat, protection of long-term productivity, and other ecosystem functions. Previously developed forest practice guidelines by states did not anticipate the increased removal of biomass and thus offer no specific guidance on removal limits needed to keep forests healthy. In general, wood that would have been left onsite under traditional harvest conditions is removed in a biomass harvest, which can mean a reduction of dead wood. Dead wood plays an important role in the ecosystem by providing wildlife habitat, cycling nutrients, aiding plant regeneration, decreasing erosion, and storing carbon. The reduction of dead wood is one of the key differences between biomass removal and traditional harvest; it should be a focus of future guidelines. Guidelines should make clear and specific recommendations to retain standing dead trees (snags), existing coarse woody material (CWM), harvest-generated CWM, fine woody material (FWM), and the forest floor and litter layer. The creation of new guidelines for forestry presents the opportunity to encourage practices that go beyond minimum acceptable practices and instead focus on enhancing the full suite of ecological values. Key report recommendations are as follows: � Consider the full range of potential impacts of biomass removals when developing new guidelines. � Use the best available science for the ecoregion(s) covered by the guidelines to determine appropriate recommendations. � Include as much public input and collaboration as possible in guideline development. � Define terms such "woody biomass" clearly and appropriately. � Make clear and specific recommendations to retain standing dead trees, existing CWM, harvest generated CWM, FWM, and the forest floor.

Development of commercially viable cellulosic ethanol Following a successful start-up in the fourth quarter of 2008, POET Research Center in Scotland, SD is now producing cellulosic ethanol at a pilot scale, completing a crucial step toward development of commercially viable cellulosic ethanol. The Scotland plant is producing ethanol at a rate of 20,000 gallons per year using corn cobs as feedstock. The $8 million endeavor is a precursor to the $200 million Project LIBERTY, a commercialscale cellulosic ethanol plant that will begin production in 2011. The pilot plant is the site of a nine million gallon per year starch ethanol production facility and a starch pilot facility. POET is pursuing an integrated starch- and cellulose-to-ethanol biorefinery model that could see cellulosic production capacity added to their 26 plants that currently produce 1.5 billion gallons of ethanol from corn per year. The pilot project is the result of a significant investment in research by POET over the last eight years toward commercializing cellulosic ethanol. In 2008 alone, POET spent $20 million on research, doubling its research staff and tripling the size of its lab in Sioux Falls.

Elextrix, LLC | www.electrix.biz energy efficiency Re-charging battery life When it comes to batteries, many consumers are in the habit of buying cheaper batteries and throwing them away once the battery's strength is gone. A company called Responsible Energy Corporation aims to educate consumers about how using throwaway batteries negatively affects the environment. The company gears its energy toward marketing rechargeable batteries for all common uses--or green batteries that can be used again and again. Responsible Energy Corporation realizes that even consumers who buy rechargeable batteries will often only buy these for the products that require them...digital cameras, games, portable music players, GPS, and other electronics that normally drain the life from a battery quickly. With more than 15 billion batteries being produced and sold worldwide annually, the company is promoting the use of rechargeable batteries, no matter what type of product or how efficiently the product uses a battery's energy. "Many of the batteries being sold are alkaline batteries. These are discarded after a single use. We want to change that by encouraging folks to spend just a little more now on rechargeable batteries to save hundreds of dollars later, while simultaneously contributing to a greener planet," said company owner Curtis Randolph. What many do not realize is the environment suffers in a three-fold manner with this many disposable batteries being sold each year. For one, batteries are often disposed of improperly. Secondly, battery factories have to use extra time and energy (along with dangerous chemicals) to create more batteries. Lastly, consumers spend their money on more batteries than are really needed throughout the year, not realizing how much they could save by simply switching to rechargeables. "Think of the new energy saver light bulbs that have become so popular in recent years. Sure, you can still get the cheaper varieties, but the energy-saver bulbs last years longer and save the consumer many dollars on their energy bills...the benefits are similar with rechargeable batteries," said Randolph. Consumers can save money by switching to Nickel Metal Hydride (NiMH) batteries. Whether AA or AAA batteries are needed, users can easily and affordably replace them with NiMH to enjoy a much longer battery life. Lithium Ion (li-ion) batteries are not normally available in consumer sizes and voltages, but there are some exceptions. Visit www.greenbatteries.com/aabattery-faqs.html to learn more.

By bringing together the resources and expertise of the public and private communities, Forward Chicago seeks to help the city achieve its greenhouse-gas emissions reduction targets, "green" the bid for the Olympic and Paralympic Games, and leave an environmental legacy for all Chicago residents. In June 2008, The Climate Group and Chicago 2016 introduced 21st Century Green Centers, geographically targeted areas surrounding proposed Olympic and Paralympic venues, a concept that was born out of Chicago 2016s environmental advisory council. Forward Chicago furthers this initiative by providing an ongoing platform for the program's partners and participating companies to work collaboratively to make Chicago the greenest, most environmentally friendly city in the country. Based on existing research, Forward Chicago has identified three major environmental challenges facing Chicago's neighborhoods: urban heat island effect, open space, and greening and flooding. Each 21st Century Green Center will feature business and nonprofits working together, focusing on various sustainability initiatives that support Mayor Richard M Daley's ambitious plans to make Chicago the most environmentally friendly city in the country. "Through this ongoing partnership, we look forward to helping Mayor Daley achieve his ambitious plans to reduce the city's greenhouse emissions to 25% below 1990 levels by the year 2020, and to 80% below 1990 levels by 2050," said Michael Allegretti, The Climate Group's head of government relations, North America.
