EIA: Solar and wind leave coal in the dust with record 2025 output

A new review of US Energy Information Administration (EIA) data by the SUN DAY Campaign reveals that solar delivered almost 9% of US electricity in the first half of 2025. Wind and solar combined produced just over one-fifth of the country’s electricity, while renewables as a whole hit nearly 28%.

Solar’s record-breaking growth

EIA’s latest monthly Electric Power Monthly report (with data through June 30, 2025) confirms that solar kept its streak as the fastest-growing major source of US electricity. In June 2025 alone, solar soared. Utility-scale solar power plants cranked out 30.1% more electricity than in June 2024, while rooftop and other small-scale solar systems grew by 10.5%. Combined, solar generation jumped 25% year-over-year and made up 10.2% of US electricity that month.

Looking at the first six months of 2025, utility-scale solar expanded by 37.6%, and small-scale systems rose 10.7%. Together, they grew nearly one-third (29.7%) compared to the same period in 2024. That meant solar provided 8.7% of all US electricity in January-June, up from 6.9% the year before.

That’s a milestone: Solar is now producing almost 45% more electricity than hydropower (6.0%), and it’s generating more than hydropower, biomass, and geothermal combined.

Wind is still a front-runner

Wind turbines supplied 11.6% of US electricity in the first half of 2025 — a 2.4% boost compared to the same time in 2024. Wind’s output was almost double hydropower’s contribution.

Wind + solar are beating coal and nuclear

Together, wind and solar accounted for 20.3% of total US electricity in the first half of 2025, up from 18.6% last year. That’s a bigger share than coal or nuclear. In fact, wind and solar generated 25% more electricity than coal and 15.6% more than nuclear over the same period.

Renewables overall are surging

All renewable sources combined – wind, solar, hydropower, biomass, and geothermal – generated 27.7% of US electricity from January through June 2025, up from 26.1% a year ago. Their output grew three times faster than total US electricity generation overall (9.2% vs. 3.0%). Renewables are now second only to natural gas, whose generation actually dropped 3.7% in the first half of the year.

Ken Bossong, executive director of the SUN DAY Campaign, added that this growth happened before the passage of the Trump/Republican “megabill,” which could slow future renewable expansion. “Nonetheless, EIA notes that US developers expect half of new electric generating capacity to come from solar in 2025 and another 13% from wind.”
