In the U.S. 8% of our energy generating capacity comes from wind turbines—that’s more than any other renewable resource—and wind power has more than tripled over the past decade. More than half of that capacity comes from just five states: Texas, Iowa, Oklahoma, California, and Kansas. According to the American Wind Energy Association, there are over 56,000 wind turbines across the country that provide a capacity of ~96,000 megawatts, enough to power more than 15 million homes. The Department of Energy projects that by 2050, that wind capacity will increase to more than 400 gigawatts.
