Wind turbines are a method of energy conversion. They take one form of energy — kinetic energy from wind — and transform it, through a series of mechanical processes, into electricity. Wind energy is considered renewable because it occurs naturally in the world around us. Earth will never run out of wind.
More than 40 percent of energy generated in the United States is used to power buildings, from heating and lighting to igniting gas-powered stoves. Decarbonizing buildings could put a serious dent in overall energy consumption, but it’s not an easy task.
