For electricity generation in Texas (primarily the ERCOT grid, which covers ~90% of the state’s load), the most recent complete full-year figures are for 2025. Natural gas remained the largest source, followed by wind, with solar surpassing coal as the third-largest source for the first time.10 Approximate full-year 2025 shares of energy supplied on the ERCOT grid (percentages of total generation; minor variations exist depending on exact categorization of gas plants and inclusion of small-scale/other sources): •Natural gas: ~41% (often broken out as combined-cycle ~33% + other natural gas ~8%) •Wind: ~23% •Solar: ~14% •Coal: ~13% •Nuclear: ~8% •Other (hydro, biomass, storage net, etc.): ~1% Renewables (wind + solar) together supplied about 37%. Natural gas is the primary dispatchable resource.0 Statewide utility-scale figures for 2025 (including non-ERCOT areas) show a somewhat higher natural gas share: natural gas ~48.7%, wind ~21.9%, coal ~11.6%, solar ~9.9%, nuclear ~7%, with the rest under 1% (other gases, hydro, biomass, petroleum). Small-scale solar added further generation.7 Context and more recent trends Texas generates more electricity than any other U.S. state. Shares fluctuate significantly by season, time of day, and weather (higher solar in summer afternoons; higher wind at night or in spring; thermal plants cover more during high demand or low renewable output). Battery storage capacity has grown substantially but contributes modestly on a net-energy basis. Partial 2026 data (e.g., early months or specific periods like July) show continued solar growth (sometimes averaging higher shares around 18% in periods), wind varying widely (e.g., lower in summer), and natural gas adjusting accordingly (often in the 40%+ range during peaks). Real-time mixes can be checked on the ERCOT Fuel Mix dashboard or EIA grid monitors; a sample mid-August 2026 daily mix for the Texas region showed roughly natural gas 35%, wind 30%, solar 18%, coal 11%, and nuclear 7% (with battery storage net negative as it charged).33 Note that these are generation (energy production) shares, not installed capacity. Renewables have lower capacity factors than thermal or nuclear plants, so capacity mixes differ (more wind/solar capacity relative to their energy output). Primary energy production in Texas is dominated by oil and natural gas extraction (Texas leads the U.S. in both), but the question’s reference to a “mix” with figures aligns with electricity generation sources.
