Solar executives say Trump attack on renewables will lead to power crunch

President Donald Trump‘s attack on solar and wind projects threatens to raise energy prices for consumers and undermine a stretched electric grid that’s already straining to meet rapidly growing demand, renewable energy executives warn.

Trump has long said wind power turbines are unattractive and endanger birds, and that solar installations take up too much land. This week, he said his administration will not approve solar and wind projects, the latest salvo in a campaign the president has waged against the renewable energy industry since taking office.

“We will not approve wind or farmer destroying Solar,” Trump posted on Truth Social Wednesday. “The days of stupidity are over in the USA!!!”

Trump’s statement this week seemed to confirm industry fears that the Interior Department will block federal permits for solar and wind projects. Interior Secretary Doug Burgum took control of all permit approvals last month in a move that the American Clean Power Association criticized as “obstruction,” calling it “unprecedented political review.”

The Interior Department blocking permits would slow the growth of the entire solar and wind industry, top executives at renewable developers Arevon, Avantus and Engie North America told CNBC.

Even solar and wind projects on private land may need approvals from the U.S. Fish and Wildlife Service if, for example, a waterway or animal species is affected, the executives told CNBC. The three power companies are among the top 10 renewable developers in the U.S., according to energy research firm Enverus.

The Interior Department “will not give preferential treatment to massive, unreliable projects that make no sense for the American people or that risk harming communities or the environment,” a spokesperson told CNBC when asked if new permits would be issued for solar and wind construction.

Choking off renewables will worsen a looming power supply shortage, harm the electric grid and lead to higher electricity prices for consumers, said Kevin Smith, CEO of Arevon, a solar and battery storage developer headquartered in Scottsdale, Arizona, that’s active in 17 states. Arevon operates five gigawatts of power equivalent to $10 billion of capital investment.

“I don’t think everybody realizes how big the crunch is going to be,” Smith said. “We’re making that crunch more and more difficult with these policy changes.”

Uncertainty hits investment

The red tape at the Interior Department and rising costs from Trump’s copper and steel tariffs have created market instability that makes planning difficult, the renewable executives said.

“We don’t want to sign contracts until we know what the playing field is,” said Cliff Graham, CEO of Avantus, a solar and battery storage developer headquartered in San Diego. Avantus has built three gigawatts of solar and storage across the desert Southwest.

“I can do whatever you want me to do and have a viable business, I just need the rules set and in place,” Graham said.

Engie North America, the U.S. arm of a global energy company based in Paris, is slashing its planned investment in the U.S. by 50% due to tariffs and regulatory uncertainty, said David Carroll, the chief renewables officer who leads the American subsidiary. Engie could cut its plans even more, he said.

Engie’s North American subsidiary, headquartered in Houston, will operate about 11 gigawatts of solar, battery storage and wind power by year end.

Multinationals like Engie have long viewed the U.S. as one of the most stable business environments in the world, Carroll said. But that assessment is changing in Engie’s boardroom and across the industry, he said.

“The stability of the U.S. business market is no longer really the gold standard,” Carroll said.

Rising costs

Arevon is seeing costs for solar and battery storage projects increase by as much as 30% due to the metal tariffs, said Smith, the CEO. Many renewable developers are renegotiating power prices with utilities to cover the sudden spike in costs because projects no longer pencil out financially, he said.

Trump’s One Big Beautiful Bill Act ends two key tax credits for solar and wind projects in late 2027, making conditions even more challenging. The investment tax credit supported new renewable construction and the production credit boosted clean electricity generation.

Those tax credits were just passed on to consumers, Smith said. Their termination and the rising costs from tariffs will mean higher utility bills for families and businesses, he said.

The price that Avantus charges for solar power has roughly doubled to $60 per megawatt-hour as interest rates and tariffs have increased over the years, said CEO Graham. Prices will surge again to around $100 per megawatt-hour when the tax credits are gone, he…
