For much of last year. the US grid looked like it might be headed for an uncomfortable detour: early data suggested demand from new data-center load could be rising fast enough to pull coal back into the picture after years of decline. The early alarm was real—demand rose by about 3 percent. and coal usage surged enough to interrupt that long downward trend.
But the story changed as the year went on. Both the demand increase and the coal rebound slowed considerably. By now, the grid is sliding back toward its baseline rhythm: slow growth in demand, with renewables—especially solar—pushing coal out.
The “oddity” this time isn’t that clean power is increasing. It’s that hydro is surging more than you’d expect from new capacity. Hydroelectric production has climbed without a corresponding increase in capacity. a mismatch likely tied to unusually warm weather in the western US. When snowpack melts early. reservoirs and streamflow can surge ahead of schedule—good news for hydro now. but a potential problem later in the year.
The first quarter of 2026 offers the clearest snapshot so far. Overall demand in the US grew by only 1.5 percent compared with the same period in 2025. Energy use in this part of the year often shifts with weather—especially for heating and cooling—but the starting conditions for 2026 were unusual. The western half of the country was unusually warm, while the eastern half experienced a deep freeze. That mix means the small demand uptick may not deserve too much weight yet; it could simply reflect seasonal extremes rather than a new and lasting demand trend driven by data centers.
Against that uneven weather backdrop, solar kept doing what solar has been doing on the grid for a while now: growing fast enough to matter immediately. Compared with the first quarter of the year before, solar was up by 24 percent. On its own, that increase offset 80 percent of the rising demand.
Zooming out, the output of the major renewables—wind, solar, and hydro—grew by 11 percent year over year. That pace is about 1.8 times the growth in demand. With renewable generation climbing much faster than total electricity needs, fossil fuels had little room to expand.
The result was a drop in fossil use overall, by about 3 percent year over year. The absolute shift in fossil output was similar in size to the demand increase, just moving in the opposite direction. And while natural gas use actually grew slightly in the first quarter, the larger loser was coal. Coal use dropped by over 10 percent—an outcome that fits the familiar pattern of coal being displaced when renewables surge.
There’s a timing wrinkle that could complicate what comes next. The data also notes that prices for natural gas have been pushed higher by the Persian Gulf conflict. but that hasn’t yet shown up as a major factor in this particular set of grid numbers. Still. it’s there in the background—one reason coal could be more or less vulnerable than the first-quarter snapshot suggests. depending on how fuel markets move later in the year.
The hydro surge also comes with its own clock. If warm weather melted snowpack early, hydro output may be temporarily boosted now while leaving less water stored for later months. So the same trend that helps push coal out at the moment may carry consequences later in the year.
For now. the US grid is doing what it’s done when weather and renewable growth line up: it’s meeting demand growth with solar and other clean power. and coal is getting squeezed hard. Last year’s fear—demand-driven interruption of the coal decline—looks like an episode that didn’t stick. The question for the months ahead is whether hydro’s unusual bump is a brief weather-driven lift. or the start of something more sustained.
