The Energy Information Administration’s April 2026 grid report shows solar power eclipsed coal‑generated electricity for the first time in U.S. history. While rooftop installations supplied a sizable share that never entered the wholesale grid, total solar output still outpaced coal’s 12 percent share, pushing solar to 9.4 percent of national generation. Utility‑scale farms dominate reported figures, while rooftop systems supply roughly half of total solar.

Coal’s decline continued despite federal subsidies, falling from 14 percent of the mix in April 2025 to 12 percent this year. Meanwhile, solar, long the cheapest new capacity, grew over 20 percent year‑over‑year, lifting its share from 8.3 percent to 9.4 percent. Longer daylight hours in April and a backlog of installations completed at year‑end amplified the shift. Early‑year seasonal lows kept solar’s overall grid share modest, underscoring April’s boost.

The crossover reshapes market signals: utilities face tighter emissions targets while investors chase solar projects with ever‑lower levelized costs. Homeowners benefit from self‑generated power that reduces reliance on the grid, and policymakers gain a concrete metric to justify further renewable incentives. Grid operators note higher solar needs storage, yet reliability stays steady. Solar’s ascendancy now overtakes coal in headline numbers, confirming the energy transition’s momentum.
