Where is Wind Energy Found?
~ Places where there is constant wind
~ Some places are better for wind turbines
~ How is the wind extracted?
~ These 3 places = electricity to supply a city the size of San Francisco
Wind as a replacement
Wind could generate 6% of nation’s electricity by 2020.
Wind currently produces less than 1% of the nation’s power.

• Advanced airfoils• "Super-magnet" generators• Low cost manufacturing• Smart power electronics• Very tall towers• "Stealth" low noise & visual impact
*Wind energy has minor impacts on our environment.
*Wind energy plants produce no air pollutants or greenhouse gases.
*Wind turbines are relatively quiet. (they are compared to the sound level of a refrigerator)
Now they coexist safely with many land uses, including schools, highways, hiking trails and farms.
*In the Renewable Energy Policy project studied 25,000 property transactions and did not find evidence of wind power reducing property values.
*The FAA requires turbines to be lit and to be at least 200 ft. tall.
***Air quality in the U.S. has improved since the Clean Air Act of 1970 because of these wind turbines.
*Have caused bird and bat collisions…mainly in the 80’s and the 90’s, so far only in the U.S.
*Negative environmental impacts of wind power come from the change in habitat that results from the clearing of the land.
***The fact that our growing energy still harms us and the environment. When using the wind turbines we have to use electricity from fossil fuels, which emits CO2,SO2,NOx, and much more.
