To claim that 2025 in the United States has been one for the history books may be the understatement of the year. So many unprecedented things have happened, that historians will have no shortage of harrowing lessons to be learned from this era.
In the clean energy space, the Trump administration launched attack after attack to slow down the clean energy in favor of fossil fuels, killing projects, investments, and jobs. By rescinding clean energy funding, pushing to abolish tax credits, coordinating across the administration to interfere with wind and solar, and so much more, they’ve set us up for bitter harvests for years to come.
And yet…
Clean energy is strong. And in 2025, it showed its strength in some really notable ways, as momentum, economics, policies, and people carried clean energy progress forward, despite it all. And it seems all the more important to celebrate it this year.
So, here are clean energy bright spots worthy of resounding cheers.
Powering up
One pillar of progress has been growth in renewable energy capacity, for more clean electricity and all the other benefits clean energy brings. And one clear shining star for 2025 is the US solar sector:
- 2025 looks set to land just a hair’s breadth away from breaking the record for new US solar installations set in 2024. Texas continued to be the leader in new solar, followed by California and—wait for it—Indiana (up from 15th two years ago). Overall, July to September 2025 was the third best quarter ever for new solar installations.
- Solar accounted for almost 80% of new electrical generating capacity through September (and 58% of all new electrical capacity, with energy storage included).
- All that installation progress helped push solar electricity to new heights: solar generation from January to September 2025 was 29% higher than in the same period in 2024.
- US solar manufacturing also grew: module manufacturing capacity increased 42% over the first three quarters of 2025, new capacity to make the solar cells that go into modules came to life in South Carolina, and new capacity to make the wafers that become the solar cells sprang forth in Michigan.
Energy storage was another fount of progress in 2025, with installations for the year projected to be more than 50% higher than in 2024, led by Texas, California, and Arizona.
All told, says the American Clean Power Association, 2025 looks “firmly on pace to surpass 2024 as the biggest clean power deployment year in history.”
Realizing possibilities
Where solar, storage, and other clean energy technologies really shine is in what they make possible in electricity markets around the country. Some examples:
- In California, gas electricity generation has fallen as solar generation has risen, and solar in the state, up 13% year-over-year for the first three quarters of 2025, looked set to surpass gas on an annual basis for the first time.
- In Texas, where electricity demand is growing fastest, clean energy played a huge role in meeting that increased demand in 2025. Solar generation January-September was 42% higher than in the same period in 2024, and solar seems poised to overtake coal in the state in 2026. The grid operator covering most of the state reported having added 20 times as much battery, solar, and wind capacity as new gas in its service territory since last winter.
- In New England, having clean energy available to meet peaks in electricity demand helped send the region’s last coal plant out to pasture. New England solar generation was almost a fifth higher in Q1-Q3.
Even on the water
Though the challenges were unprecedented for offshore wind, 2025 also brought noteworthy happenings in that space. Construction progressed on the next generation of projects, aimed at serving Connecticut, Massachusetts, New York, Rhode Island, and Virginia, and several large-scale ones should reach full power in 2026 (if I didn’t just jinx it…). In service in Virginia to aid the work is the Charybdis, the brand-new wind turbine installation vessel that is the first built in the United States (Texas). Virginia’s offshore wind project will be one of the world’s largest when completed next year, capable of producing enough energy for more than 600,000 Virginian households.
As some of the Trump administration’s spurious excuses to halt under-construction offshore wind projects failed to stand up to legal scrutiny, the importance of offshore wind for economies—not just as a source of clean electrons—was even clearer than usual in the range of voices pushing back and speaking out in opposition to the administration’s monkeying. Those included labor unions, business networks, and even the Republican member of Congress for the Virginia project staging area and Speaker of the House Mike Johnson.
Meanwhile, the first operating large-scale US offshore wind project, serving Long Island, showed strong results in its first year—including in the winter months, when offshore wind power comes in particularly handy. New England too was benefitting from offshore turbines, before the projects themselves even reached completion: injections of electricity into the region’s grid led to wind generation from January to early December 2025 that was 26% higher than in the same period in 2024, and led in mid-December to a record for peak wind production that was 29% higher than 2024’s peak.
Lots more to come
As technology moves forward, so do some leading states. Despite—or because of—the federal moves in the wrong direction, multiple states doubled down on their moves toward a clean energy economy in 2025. Maine, for example, committed to 100% clean electricity by 2040. California extended and strengthened its “cap and invest” program. Illinois passed a comprehensive clean energy package. And, because clean energy matters at all scales, it’s worth celebrating Michigan’s moves to make it easier for customers to connect distributed renewable energy systems (think rooftop solar) to the electric grid, and Utah’s embrace of balcony solar.
And there’s a lot more to come for clean energy, despite the even rougher seas ahead in the near term under this administration. Continuing affordability concerns will guide even some slow-to-come-around people to recognize solar and wind as often the cheapest source of new electricity generation. Decision makers and the rest of us who care about good jobs and economic development will continue to push for more policies to accelerate the move to clean energy. Innovation, economies of scale in products and projects, and continued international progress will all make clean energy even more attractive.
There’s a lot about 2025 I’d really like to be able to undo, or forget. But clean energy’s progress despite all that the Trump administration threw at it is notable, and it seems important to celebrate those accomplishments as we go into the new year. Not least to keep reminding ourselves of the enormity of what’s already possible and what’s yielding dividends right now, today, and will be long into the future.
