Last year saw wind generation in the U.S. overtake hydroelectric generation for the first time, according to data from the U.S. Energy Information Administration (EIA).
Released Wednesday, the figures from the EIA’s “Electric Power Monthly” report show that yearly wind generation hit a little over 300 million megawatt hours (MWh) in 2019. This was roughly 26 million MWh more than hydroelectric production.
Wind now represents the “most-used renewable electricity generation source” in the U.S., the EIA said.
Overall, total renewable electricity generation — which includes sources such as solar photovoltaic, geothermal and landfill gas — at utility scale facilities hit more than 720 million MWh in 2019, compared to just under 707 million MWh in 2018. To put things in perspective, generation from coal came to more than 966 million MWh in 2019.
According to the EIA’s “Today in Energy” briefing, which was also published Wednesday, generation from wind power has grown “steadily” across the last decade.
This, it added, was partly down to the extension of the Production Tax Credit, or PTC. According to the EIA, the PTC is a system which gives operators a tax credit per kilowatt hour of renewable electricity production. It applies for the first 10 years of a facility’s operation.
At the end of 2019, the country was home to 103 gigawatts (GW) of wind capacity, with 77% of this being installed in the last decade. The U.S. is home 80 GW of hydroelectric capacity, according to the EIA.
“The past decade saw a steady increase in wind capacity across the country and we capped the decade with a monumental achievement for the industry in reaching more than 100 GW,” Tom Kiernan, the American Wind Energy Association’s CEO, said in a statement issued Thursday.
