Power Mix for the First Month Ever What I Cover Tsvetana Paraskova is an energy and commodities journalist who has contributed to Oilprice.com for nearly a decade, covering global energy markets, commodities,… Solar power held a record-high 12.8% share of U.S.
electricity supply in May, overtaking coal-generated power for the first full month on record, energy think tank Ember said in areporton Wednesday.
While the share of solar-generated power jumped to a record high for a full month, the share of coal in the U.S.
electricity mix slumped to 12.2% last month, the fourth-lowest monthly share of coal ever.
Solar generated an all-time high total of 45.5 terawatt-hours (TWh) in May, up by 17% from a year earlier and surpassing the previous record set in July last year, according to Ember’s data.
In May, solar also became the third-largest source of electricity in the U.S., behind natural gas and nuclear power generation.
At the same time, coal generation hit an all-time monthly low of 39.3 TWh in April 2026.
Coal power output rebounded to 43.4 TWh in May, but still remained 11% below May 2025 levels.
“Overtaking coal for the first month on record shows just how far solar has come, from a niche contributor to the third-largest and fastest-growing source of power in the US electricity system,” said Nicolas Fulghum, Senior Data Analyst at Ember.
“From Texas to California, markets across the US are betting on solar to meet rising power needs,” Fulghum added.
Despite the Trump Administration’s assault on renewable energy andsupport for the coal industry, solar and wind power generation in the United States is booming, including in many red states that President Trump won such as Texas, Florida, Ohio, Indiana, Michigan, Arizona, and Mississippi.
In a separatereportalso out on Wednesday, the Solar Energy Industries Association (SEIA) and Wood Mackenzie said that despite changing tax policy and regulatory actions targeting clean energy, solar and energy storage represented 91% of all new capacity installed in the U.S.
