1 Wind Energy By Evan Ruderman

2 What is it? Conversion of wind energy into a useful form of electricity Over past 5 years installations have grown by 27.6% Currently generates 2.5% of world’s needed energy Will be able to generate 3.35% by 2013 Should be able to generate 8% by 2018

3 Can be utilized greatly: Denmark- 21% Portugal- 18% Spain- 16% Ireland- 14% Germany- 9%

4 Types of Wind Energy Sail- propel a ship Windmills- mechanical energy Wind pumps- pumping or draining water Wind turbines- make electricity (wind farms- 100s of wind turbines)

5 History Has been used to propel boats for over 5,500 years Began to be used to power irrigation pumps in 7 th century UK began experimenting with wind power, the US began to experiment with it too January Charles F. Brush harvested electricity, powered his house and lab with it 1970’s NASA started testing, developed many modern features of the wind turbine Modern turbine industry started in 1979 by Danish Manufacturers First wind farm in US was on Crotched Mountain

6 Offshore Wind Energy Wind farms can be built offshore Offshore offers better wind speeds Some people complain it ruins coastline

7 Downsides Visual impairment Noise (nearby) Sometimes need to clear land Sometimes need to build roads Can be unpredictable

8 Overall Pros Alternative to fossil fuels Renewable Can be used on or offshore Very clean No green house gases produced About same price as coal or natural oil Uses little land Cons Can visually impair Sometimes land needs to be cleared Can be unpredictable
