In 2025, a record 14 U.S. states (up from 12 states in 2024) generated more than 30% of their in-state electricity from wind, solar, and geothermal sources – the 10 shown above plus Vermont, Texas, Hawaii, and Minnesota. Led by perennial leader Iowa at 61%, these top performers span deep blue coastal states like California to red Great Plains strongholds like South Dakota and Oklahoma, proving once again that clean energy adoption can transcend political divides. Although wind generation declined slightly in many Great Plains states last year because of lower-than-usual wind speeds and slowed capacity rollout, solar generation continued to rise after many record-breaking solar farms came online in 2024. New Mexico and California expanded their solar resources to leapfrog Kansas in total percentage of generation in 2025, while Texas, which could soon join the Top 10, has increased its solar generation from less than 1% in 2015 to 10.74% last year. The EIA projects that the U.S. will add a record 43.4 GW of utility-scale solar in 2026, alongside 24.3 GW of new battery storage. These projected additions will result in more states meeting an increasing share of their growing in-state electricity generation needs with renewable energy sources.
