While other states talk about renewable energy, Texas is actually making it happen. The Lone Star State set 17 solar generation records in 2025 alone, with solar output peaking at a whopping 29.8 gigawatts on September 9th. That’s enough to power millions of homes. For seven straight hours that day, solar supplied over 40% of Texas electricity. Not bad for a state once synonymous with oil derricks.
The numbers tell the story. Solar generated 45 terawatt hours in the first nine months of 2025—50% more than 2024 and quadruple what it produced in 2021. During summer’s scorching peak hours, solar delivered nearly 27% of electricity demand. This impressive performance helped solar consistently outperform coal generation, which had only a 12.5% market share. Texas now has more than 22 gigawatts of installed solar capacity. The vast majority sits in West Texas, where sunshine is abundant and land is cheap.
Texas solar output has skyrocketed, delivering 45 TWh in 2025’s first nine months—quadruple what it produced just four years ago.
Corporate America has noticed. Meta recently backed ENGIE’s massive 600 MW Swenson Ranch solar project, scheduled to come online in 2027. These companies aren’t tree-hugging for PR points—they’re chasing profits. Solar has simply become the cheapest, fastest way to add electricity capacity. Economics, not environmentalism, is driving this train.
The impact on Texas’s energy mix is undeniable. Solar and wind together supplied 36% of ERCOT’s electricity from January to September 2025. That’s pushing natural gas use down from 50% to 37% during peak hours. Coal and nuclear? They’re the dinosaurs in this story. Literally. Texas has become a key storage leader with its substantial investment in energy storage capacity, accounting for a significant portion of the nation’s total deployment alongside California.
Residential solar is catching on too, with more than 250,000 Texans putting panels on their roofs. Meanwhile, battery storage is growing alongside solar, helping smooth out supply when the sun isn’t shining. During summer evenings, batteries provided an average of 4 GW of power around 8 pm when solar production declined.
Remember when critics claimed renewables couldn’t power a major economy? Texas is proving them wrong. The state’s electricity demand hit a record 372 terawatt hours in the first nine months of 2025—up 23% since 2021—and solar helped keep the lights on. No hippie communes here, just hard economics crushing tradition.
