Different Clean Air Technologies

Wind is a renewable energy source that emits no pollution. It is the fastest-growing “green” energy in the U.S. and provides light to the Statue of Liberty. Wind farms—clusters of huge windmills—produce electricity by using the motion of their blades to spin a shaft connected to a generator. Experts estimate that the electricity created in 2006 by America’s wind farms will displace some 15 million tons of carbon dioxide. Over five million acres of forest would be needed to absorb that much CO2. Some people oppose wind farms because they occupy large tracts of land and can sometimes harm birds, but most agree that their environmental costs are much lower than those of fossil fuels.
