4. Main Point Wind power can be used to solve the current energy resource crisis Wind power can be used to solve the current energy resource crisis –Release no emissions into the atmosphere –Most efficient energy source at our disposal – produce 23 times the energy they consume –There is a relatively infinite supply and wind is constantly blowing – no sense in letting it go to waste

5. Environmental Impacts -Positive- United States creates 10 million megawatt-hours of electricity each year. This directly prevents: United States creates 10 million megawatt-hours of electricity each year. This directly prevents: –6.7 million tons of carbon dioxide –37,500 tons of sulfur dioxide –17,750 tons of nitrogen oxide
