A lot of people think only of solar when discussing renewables, but wind power has long been ahead of solar. Now wind has surpassed hydro, the original renewable electricity source, in the US.

According to the U.S. Energy Information Administration’s newly-released Electric Power Monthly, the exciting milestone means that wind is now the top renewable source of electricity generation in the country—a position previously held by hydroelectricity for several decades.
Annual wind generation totaled 300 million megawatthours (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.
As of the end of 2019, the United States had 103 GW of wind capacity, nearly all of which (77%) were installed in the past decade. The United States has 80 GW of hydroelectric capacity, most of which has been operating for several decades. Only 2 GW of hydroelectric capacity has been added in the past decade, and some of those additions involved converting previously non-powered dams.
