U.S. Adds Record 48.5 Gigawatts of Clean Energy in 2025

The United States just had its biggest clean energy year on record, bringing 48.5 gigawatts of new wind, solar, and battery capacity online in 2025. That's enough power to match 23 Hoover Dams, and it happened because these energy sources are now the cheapest and fastest to build.

The news comes from a new report by Environmental Defense Fund and Atlas Public Policy tracking clean power growth across the country. While the numbers represent a historic milestone, they could have been even higher.

More than 60 gigawatts of clean energy capacity had been expected to come online last year. About 20% of those projects got delayed, and another 13 gigawatts were cancelled entirely, in part due to federal policy changes that blocked some developments.

But here's what those obstacles couldn't stop: Americans now have more than 217 gigawatts of clean power capacity either planned or under construction. That's almost five times more than the fossil fuel capacity in the pipeline.

The momentum is strongest in unexpected places. Texas leads all states for clean power capacity, with more than double what California has installed. Republican-led districts hold 80% of existing, under construction, and planned clean energy projects nationwide.

Some delayed projects are already bouncing back. Vineyard Wind, an offshore wind project that faced cancellation attempts, just announced its construction is complete and ready to power homes.

The Ripple Effect: This surge in clean power couldn't come at a better time. Electricity demand is set to grow twice as fast over the next five years compared to the previous decade, driven by everything from data centers to electric vehicles. As power needs and bills climb, affordable energy sources become critical for families and businesses alike.

Grace Hauser, a technical analyst at Environmental Defense Fund, points out the market reality. "Clean energy sources like wind, solar and batteries are dominating new additions to the grid because they are the most affordable sources of energy and relatively quick to build," she explained.

The economic benefits hit home locally. Of the 30 congressional districts with the highest clean energy capacity, 27 are represented by Republicans, bringing jobs and investment to communities that need both.

Every gigawatt of new clean power means cleaner air, more stable energy prices, and jobs building the future.
