US renewable energy hits record milestone in April

The US renewable energy sector achieved a historic milestone in April 2026, with solar power outpacing coal-fired electricity for the first time on record. Preliminary data from May had already hinted at this shift, but the official release of the Energy Information Administration’s April grid data confirms the breakthrough,though with one important nuance.

That nuance is that a significant portion of the solar electricity generated never actually reached the grid. Instead, it came from rooftop solar installations and was consumed directly by the buildings where it was produced. So while solar’s total output surpassed coal’s in April, the grid itself still relied more heavily on coal for its delivered power.

The broader trend is clear: coal’s decline continues despite repeated government efforts to revive it. After a brief uptick last year, coal use resumed its downward slide, even as the Trump administration pushed to keep plants open. Meanwhile, solar energy keeps surging, fueled by its status as the cheapest way to add generating capacity in most of the US. But this growth started from a relatively small base, and early spring months typically see lower solar production. Even with year-over-year growth exceeding 20 percent, solar still accounted for only about 6 percent of total US electricity in April, compared to coal’s 16 percent.

The April milestone is a symbolic victory for renewables, but it also underscores the gap between total generation and grid delivery. Rooftop solar, while a powerful force in reducing household emissions, does not directly displace coal on the transmission network. Still, the trajectory is unmistakable: solar is on track to overtake coal more permanently as its capacity expands and storage solutions improve.
