United States Solar Power Overtakes Coal and Wind Generation in May

Solar generated more electricity than coal and wind combined in May, according to the U.S. Energy Information Administration, marking the first month the nation’s clean‑energy source outpaced both fossil and other renewable generation.

EIA data showed solar’s share of total U.S. electricity rose to a record high, while coal output fell sharply and wind production lagged behind, reflecting a broader 11 percent growth in renewables during the first quarter of 2026.

Coal plants saw a month‑over‑month decline across the nation’s baseload fleet, cutting several gigawatt‑hours of output, reducing carbon emissions and prompting utilities to reconsider future coal investments amid rising solar capacity and tighter environmental rules.

Energy Mix analysts say the May milestone could accelerate policy support for solar incentives and signal a turning point toward a cleaner grid, though grid reliability and storage remain key challenges, especially as solar output peaks in summer demand periods.
