Dear Friends of the juwi Group, They are the real deal. Decentralized, renewable energies are safe, profi table and reliable – and a worldwide growth market. These are the findings of the Renewables 2011 Global Status Report, recently published by the Paris-based policy network REN21. The study shows that worldwide renewable energy production increased in 2010, despite the economic downturn. And renewable energies have other advantages: they bring new prosperity to regions, create local jobs and help to improve the infrastructure. Considering these facts, it is difficult to understand the German plans for the country’s energy transition. Instead of developing decentralized sun, wind and bio energy systems, decision-makers opted to construct gigantic off shore wind energy installations in the North and Baltic Sea. These will cost billions and only strengthen the power monopoly of the four largest power providers. In addition, thousands of kilometers of high voltage lines will be necessary to transport electricity from North to South. Germany’s energy revolution could be much cheaper and faster than is planned by the federal government, and decentralized renewable energy projects could save consumers more than ten billion euros. This is what drives juwi: to continue working for an energy supply consisting of 100 percent renewable energy with onshore wind farms, large and small solar power systems, bio energy projects and intelligent solutions for the efficient use of energy resources. In the current issue of juwinews you can read about our latest wind, solar and bio energy projects and get a very personal insight into juwi history and juwi stories. On the occasion of juwi’s 15th anniversary, we have published a special edition. Enjoy reading!

Spectacular Balancing Act at Dizzying Heights Fever-pitch excitement in WĂśrrstadt. At the beginning of April, approx. 5,000 guests visited the wind farm near the company headquarters to attend the opening of the on-site climbing park. At the same time, they were given the opportunity to learn about renewable energy and the juwi group. The highlight of the day was the artistic performance of a slackliner who crossed between the mighty Enercon E-82 tower and the 33-meter diving platform on the Powerfan using a rope that was only three centimeters in diameter. If a climbing adventure in the shadow of wind turbines is what you‘re after, come and visit juwi. (Photo: Stephan Dinges, juwi)


Insights

Mobility Concepts for Companies and Municipalities Gasoline prices at gas stations are at record levels. But businesses and municipalities can escape from the price spiral – with E-mobility. Bring renewable energy to the road – juwi can design an infrastructure with carports and charging stations and a coherent E-mobility concept that is tailored to individual needs. The car fleet at juwi headquarters demonstrates every day that cars and motorcycles can be powered with wind and sun energy.

Roadmap to the age of renewable energies We could make the transition to a complete renewable power supply in 10 to 20 years. The juwi group has written a position paper that we are introducing into the political debate. 1 The expansion must be strictly decentralized and regional. 2 Increased usage of the wind potential in Southern states such as Hesse, Baden-Württemberg and Bavaria. 3 Accelerated repowering in northern Germany. No arbitrary height limits for wind turbines that cap the potential to generate clean power. 4 Make it possible again to install solar systems in the most inexpensive areas – such as fallow lands and fields. 5 Development of storage technologies for regenerative energies.

However, in recent years juwi has diversified and developed at an extraordinary rate. Its wide range of services is unique on the market and contributes to the realization of our 100 percent vision.” juwi Bio GmbH has also diversified its product portfolio, so the project pipeline is expanding fast. In his work as managing director, Gerd Kück will be primarily responsible for overseeing the financing of these projects. “There are a lot of attractive investment opportunities in the bio energy industry.

Wood-Fired Power Station in Dotternhausen Delivers Environmentally Friendly Energy The community of Dotternhausen in the Swabian Alps is aiming to become energy selfsufficient. An important contribution to this project will be juwi‘s newly built wood-fi red power station, which generates 1.26 megawatts of electrical power and 6.9 megawatts of thermal power. The power is fed directly into the grid, while a large proportion of the heating energy will be used by a neighboring wood pellet factory that is currently being project managed by juwi. juwi Bio GmbH is not only responsible for the construction of the two sites; the company also operates them and sources the raw materials. The wood-fi red power station is something of an omnivore in the sense that the boiler plant is powered using aff ordable natural materials such as short logs, tree tops, branches and materials from the particle board and pulp industries. Around 36,000 tons of wood will be processed each year and up to ten new jobs will be created in Dotternhausen.

Green Buildings

New Building, New Carports Three years after the construction of juwi‘s headquarters in Wörrstadt, public interest in the energy-efficient premises is still going strong. In the fi rst half of the year alone, approx. 3,400 visitors came to take a look around the two buildings and state-of-the-art technical equipment. When guests see the rows of temporary containers to the east and south of the office complex, one thing soon becomes clear: in terms of staff numbers, juwi is still growing at a rapid pace. Following previous expansions in 2009 and 2010, juwi is now planning for a third expansion in order to keep up with this development. The new building section to the south of the juwi complex will function as the new central building. The inauguration is scheduled for the beginning of 2012. The raw facts alone are impressive: 9,000 square meters of office space, space for 400 employees and a new cafeteria with a pitched roof and balcony that is designed to provide 2,000 meals a day. The building can be accessed via a main entrance, with a courtyard located on the western side. From there, two slightly off set building wings lead to a third complex. The eastern end of the area is bordered by a pond with a view of the wind farm and the rope course.
