Solar Passes Coal in Texas for First Time Ever

Texas just crossed a threshold nobody saw coming this fast: solar power is beating coal.

In the first half of 2024, utility-scale solar in Texas generated more electricity than coal for five out of six months. It's the first time that's happened in the country's leading coal-producing state, and experts say it's not a fluke.

The numbers tell a stunning story. Texas added 9,373 gigawatt-hours of solar generation compared to last year, a 35 percent jump. That's enough clean energy to power roughly 870,000 homes for an entire year.

"Five years ago, coal still generated more than seven times as much electricity as solar in Texas," said Nicolas Fulghum, a senior analyst at Ember, a clean energy research group. "That gap closing so fast tells you this isn't all about policy. Solar is winning on cost and deployment speed."

Texas led the nation in overall electricity generation growth, producing 9,086 more gigawatt-hours than the same period last year. But here's the remarkable part: solar alone grew enough to offset decreases in other energy sources. Natural gas output stayed flat, and coal continued its decline.

The shift is happening despite federal policies that forced some coal plants to stay open against their owners' wishes. Those plants remain available during peak demand, but on typical days, cheaper alternatives like solar and natural gas make more economic sense.

Nationwide, renewables claimed 28.5 percent of electricity generation in the first half of 2024, up 2.2 percentage points from last year. Coal lost an identical share, dropping to 14.4 percent. Natural gas remained the leader at 38.4 percent, with nuclear holding steady at 17.1 percent.

Other states are writing their own clean energy stories. Washington's hydropower bounced back after years of drought. Tennessee boosted nuclear output. Even New Mexico, traditionally coal-heavy, saw solar gains alongside its remaining coal plants.

The Ripple Effect

Texas proves that market forces can drive massive energy transitions faster than policy alone. The state's solar surge happened without major new incentives, powered instead by falling costs and Texas-sized ambition. As data centers and growing populations demand more electricity, the Lone Star State is meeting that need with sunshine rather than smokestacks.

What happens in Texas rarely stays in Texas, especially when it comes to energy innovation.
