Trump's return brought stiff headwinds for clean energy. So why are advocates optimistic in 2026?

NEW YORK (AP) There were some highs amid a lot of lows in a roller coaster year for clean energy as President Donald Trump worked to boost polluting fuels while blocking wind and solar, according to dozens of energy developers, experts and politicians.

Surveyed by The Associated Press, many described 2025 as turbulent and challenging for clean energy, though there was progress as projects connected to the electric grid. They said clean energy must continue to grow to meet skyrocketing demand for electricity to power data centers and to lower Americans’ utility bills.

Solar builder and operator Jorge Vargas said it has been “a very tough year for clean energy” as Trump often made headlines criticizing renewable energy and Republicans muscled a tax and spending cut bill through Congress in July that dramatically rolled back tax breaks for clean energy.

“There was a cooldown effect this year,” said Vargas, cofounder and CEO of Aspen Power. “Having said that, we are a resilient industry.”

Plug Power president Jose Luis Crespo said the developments — both policy recalibration and technological progress — will shape clean energy’s trajectory for years to come.

Much of clean energy’s fate in 2025 was driven by booster Joe Biden’s exit from the White House.

The year began with ample federal subsidies for clean energy technologies, a growing number of U.S.-based companies making parts and materials for projects and a lot of demand from states and corporations, said Tom Harper, partner at global consultant Baringa.

It ends with subsidies stripped back, a weakened supply chain, higher costs from tariffs and some customers questioning their commitment to clean energy, Harper said. He described the year as “paradigm shifting.”

Trump called wind and solar power “the scam of the century” and vowed not to approve new projects. The federal government canceled grants for hundreds of projects.

Many energy executives said this was the most consequential policy shift. The bill reshaped the economics of clean energy projects, drove a rush to start construction before incentives expire and forced developers to reassess their strategies for acquiring parts and materials, Lennart Hinrichs said. He leads the expansion of TWAICE in the Americas, providing analytics software for battery energy storage systems.

Companies can’t make billion-dollar investments with so much policy uncertainty, said American Clean Power Association CEO Jason Grumet.
