U.S. coal-fired electricity generated totaled 774 million megawatthours (MWh) in 2020, which is less than both natural gas-fired (1.6 billion MWh) and nuclear-powered generation (790 million MWh), according to the U.S. Energy Information Administration’s (EIA) Electric Power Monthly. Last year marked the first time that coal was not the largest or second-largest source of annual electricity generation in the United States since at least 1949. However, EIA expects U.S. coal-fired electricity generation to increase and for nuclear-powered electricity generation to decrease in both 2021 and 2022.
