Wind and solar generated more electricity than coal through May, an E&E News review of federal data shows, marking the first time renewables have outpaced the former king of American power over a five-month period.
The milestone illustrates the ongoing transformation of the U.S. power sector as the nation races to install cleaner forms of energy to reduce greenhouse gas emissions from fossil fuels. Power markets have witnessed a precipitous drop in coal-fired generation this year, driven by low natural gas prices, a mild winter and a wave of coal plant retirements.
“From a coal perspective, it has been a disaster,” said Andy Blumenfeld, an analyst who tracks the industry at McCloskey by OPIS. “The decline is happening faster than anyone anticipated.”
Renewable energy generation exceeded coal-fired power in 2020 and 2022, but only when hydropower was counted as a source of renewable energy, according to figures compiled by the U.S. Energy Information Administration.
This year has been different. Wind and solar sources generated a combined 252 terawatt-hours through the first five months of 2023, compared with coal output of 249 TWh, EIA data shows. Hydro generated an additional 117 TWh through May.
EIA’s numbers for April and May are preliminary, said Chris Higginbotham, an agency spokesperson.
“Our official estimates from the Electric Power Monthly show that combined electricity generation from wind and solar exceeded generation from coal in January, February and March,” he said. “Our real-time data, which is subject to revision, indicate that trend continued in April and May.”
