In 2019, U.S. annual wind generation exceeded hydroelectric generation for the first time, according to the U.S. Energy Information Administration’s Electric Power Monthly. Wind is now the top renewable source of electricity generation in the country, a position previously held by hydroelectricity.
Annual wind generation totaled 300 million megawatt hours (MWh) in 2019, exceeding hydroelectric generation by 26 million MWh. Wind generation has increased steadily during the past decade, in part, because the Production Tax Credit (PTC), which drove wind capacity additions, was extended. Annual hydroelectric generation has fluctuated between 250 million MWh and 320 million MWh in the past decade, reflecting a stable capacity base and variable annual precipitation.
