U.S. Energy Information Administration (EIA). Back on March 29, wind turbines produced 2,017 gigawatt-hours (GWh) of electricity in the lower 48 states, making wind the second-largest source of energy just behind natural gas. "Daily wind-powered electricity had surpassed coal-fired and nuclear electricity generation separately on other days earlier this year, but had not surpassed both sources on a single day," the EIA said.
Data from that day showed Americans got their power from natural gas (31%), wind (19%), nuclear (19%), coal (17%) and other sources (14%).
Texas has the most wind turbine capacity among states, as of December 2020. That year, Texas generated more electricity from wind than the next three highest states (Iowa, Oklahoma, and Kansas) combined, according to the EIA.
In Iowa and Kansas, wind is the most prevalent source of in-state electricity generation. In both states, wind surpassed coal as the state’s top electricity generation source in 2019.
