Renewable Energy Definition Energy from sources that naturally replenish over time and are inherently cleaner than currently dominant fuel sources: oil, coal and natural gas.

Why is Renewable Energy Necessary?

Problems „

Energy costs can eliminate ability to operate ™Oil ™Natural gas ™Electricity ™Gasoline


Remote locations of tourist destinations = ™Higher fuel costs ™Lower fuel availability ™High amounts of atmospheric pollution ™Greater expense to travel

Challenges for Hawaii „ „




Main industry is tourism Petroleum provides nearly nine-tenths of MDC5 all the energy consumed in Hawaii The transportation sector leads energy demand due in large part to heavy jet fuel use Large potential for MDC7 wind and solar energy

Slide 12 MDC4

Hawaii energy facts „

Energy Use ™ In 1995 Hawaii ranked 50th in energy use per capita in the U.S. ™ Hawaii spends $2.76 billion on energy each year ™ This equals 8% of the states GDP


Price of Electricity ™ Hawaii has the highest electrical rates in the country ™ In 2003 residents paid an average of 16 cents per kilowatt hour, while the average in the rest of the U.S. was only 8 cents per kilowatt hour


Cost ™ As of 2002 the average household paid $123.65 on their monthly electric bill

Challenges for Alaska „

Most Alaskan consumers are not linked to large, interconnected grids through transmission and distribution lines


Communities are far away from each other and difficult to access


Rural communities rely almost exclusively on diesel electric generators


Alaskans operate one of the Nation's largest fuel cell systems and the world's largest battery storage system


Alaska’s numerous rivers offer some of MDC8 the highest hydroelectric power potential in the US


Large swaths of the Alaskan coastline offer wind and geothermal energy potential


Due to harsh weather conditions, Alaska’s oil infrastructure is particularly vulnerable to weather-related accidents and disruptions. E.g. Exxon Valdez

Slide 17 MDC8

Once again, let's make the problems more detailed here. Show costs, consumers, lack of electricty per consumer, etc. On another slide, let's create some numbers on potential. Mark D. Crowdis, 10/16/2008

Challenges for the Galapagos Islands „

Fuel is handled, transported and stored at several stages before consumption, increasing the probability that leaks will occur


Usage of diesel fuel for transportation on land and water, and for electricity generation is both inefficient and highly polluting


Waste disposal from various energy sectors harms ground water quality, as reinjection of waste into ground water is commonplace

How can renewable energy be part of the solution?

Business case for clean energy „

„ „




Rising cost of oil and declining cost of clean energy makes clean energy more cost effective in the long run Secure power supply Islands, seashores, mountains and other ecotourism locations are abundant in renewable resources such as wind, solar, and geothermal Remoteness of ecotourism locations makes importing fossil fuels costly as well as damaging to the environment Clean energy is low in environmental impact and helps to preserve the pristine nature of ecotourism locations Clean energy appeals to customers of ecotourism

Environmental Benefits „ „ „


Cleaner air and water Reduced greenhouse gas emissions Less spoilage of the landscape through the erection of transmission grids Less damage to the environment in the form of oil spills and air pollution

Biomass Market PAST ƒ

Combustion of bio materials, such as wood and waste, since beginning of civilization


Some of the first automobiles ran on bio-based fuels


Less than 200 MW in 1979


10 GW capacity in US, 7 GW derived from forest-product-industry and agricultural-industry residues, 2.5 GW of municipal solid waste (MSW) generating capacity, and 0.5 GW of other capacity


Provides about 14% of world’s primary energy


Co-firing of biomass and typically coal can reduce amount of fossil fuels used


Biodigestion systems in commercial operation, pyrolysis and gasification in commercial use in limited applications


$0.05 – 0.12 per kWh


Pyrolysis and Gasification become more widespread technologies


Growth averaging 2.5% per year will continue


Potential capacity of 55 GW in 2010
