2. What is Renewable Energy? "Renewable energy: Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun, or from other natural movements and mechanisms of the environment.” Non-renewable energy resource: an energy resource that is not replaced or is replaced only very slowly by natural processes.
3. Renewable energy usage in the last decade Since the year 2000 the amount of renewable energy used has gone up drastically. From a nearly immeasurable amount in 2000 to almost 10 million in 2008.
12. Wind Energy in the U.S. The United States is the world leader in wind energy production Produced 35,159 megawatts in 2009 Texas produces more than any state with 9,728 megawatts captured in 2009 Employs 85,000 people in the U.S. Illinois produced 1,547 megawatts in 2009
13. Wind Energy Abroad Germany trails the U.S. by about 30% in total production Together the European Union produces over twice as much as the U.S. Map

15. Interesting Fact The world’s largest wind turbine is the E-126 first built in Emden, Germany E-126 can also be found in Belgium and Sweden It is 650 ft tall with a rotor diameter of 413 ft Built in 2007
22. Geothermal Across the Globe Over 24 countries use geothermal energy The Philippines is the number two producer Geothermal is Iceland’s main energy source Worldwide 10,715 MW of power are produced
23. Pro vs. Cons PROS Once installed it is very cheap to operate Not dependent on gas or electricity to provide heat Low emissions Green energy CONS Amount of land required Start up costs are expensive Lack of accessible sites

25. Companies & Users The Geothermal Energy Association provides its members breaking news on the subject Mitsubishi: +80 different locations worldwide Sky Power Systems, GeothermEX Inc, and Mitsubishi Power Systems Inc. are the major plants in California
26. Solar Power Solar power is created by collecting sunlight and converting it into electricity This process is called photovoltaic or pv for short This is done by using solar panels, which are solar cells made from silicone that absorb the sun’s radiation Solar cells produce direct current electricity Can be used to power equipment or to recharge a battery

28. America’s Potential for Solar Power You ask why not use solar energy since there are more pros than cons? Top states of potential solar energy New Mexico Arizona Nevada Utah California Solar Calculator American Solar Power
29. Water Power: as renewable energy +(Hydropower refers to process in which water is used as means to generate electricity.)+ Became widespread: 18th Century First to use: Greeks
30. United States: Hydropower Usage 81 % of our nations renewable electricity generation deriving from HydropowerIn the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power. (1940) Now 6-8% The old “Schoelkopf Power Station No. 1” near Niagara Fallsin the U.S. side began to produce electricity in 1881. By 1889 there were 200 Hydroelectricity plants within the U.S. Very few companies that make hydroelectric turbines, can be purchased/used to power homes, small businesses, and small scale farms.
31. Where the rest of the fits: Hydropower is to thank for 19% of total electricity production worldwide. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States –Energy Information Administration. Approximately 2/3 of the economic possible potential remains to be developed. Untapped hydro resources are still abundant in Latin America, Central Africa, India and China. In 1878, the world's first house to be powered with hydroelectricity was Cragside in Northumberland, Enlgand. New Zealand’s electricity is 80% renewable (mostly hydropower). In South America, overall about 40% of electrical generating capacity is hydroelectric. Brazil yielded a percentage of 86% in 1998. Over 50% yeilds of potential generating capacity for the following countries: Chile, Colombia, Paraguay, Peru, and Venezuela. In Chile, a $0.5 billion renewable energy project recently suspended due to controversy over relocating indigenous peoples. China’s Yangzte River projects are the world’s most ambitious due to motivation of two month death tolls of 3,000 dead, 5,000,000 homeless in a 1998 flood. Countries worldwide are doing extensive research as well as developing budget’s for such facilities.

35. In Conclusion In conclusion renewable energy is a growing industry that not only benefits the businesses involved but also is good for reducing global warming and our dependence on fossil fuels. There are many types of renewable energy all of which have their own positives and drawbacks
