Eighteen states sued the Trump administration Monday over its halting of permits for wind-energy projects, arguing that its actions posed an existential threat to the burgeoning industry.

“This administration is devastating one of our nation’s fastest-growing sources of clean, reliable and affordable energy,” said Attorney General Letitia James of New York, which is one of the plaintiffs. She said the halt threatened “the loss of thousands of good-paying jobs and billions in investments” and was “delaying our transition away from the fossil fuels that harm our health and our planet.”

The halt on federal permits for wind energy was first laid out in a Jan. 20 executive order, one of a barrage that President Trump signed immediately upon taking office. It directed agencies to stop all permits for wind farms pending federal review.

The lawsuit says that, by complying, federal agencies have put major investments that have already been made at risk. The order also instructed the United States attorney general and the interior secretary to explore “terminating or amending” existing leases to wind farms, further increasing uncertainty for companies.

The wind industry provides about 10 percent of the nation’s electricity, and has many new projects under development, particularly in the Great Plains and the Atlantic Ocean.

Last month, the Trump administration halted a major wind farm under construction off the coast of Long Island, the Empire Wind project. It was designed to provide enough electricity to power a half-million homes. It had already received the permits it needed, but Interior Secretary Doug Burgum suggested the Biden administration’s analysis during the approval process was rushed and insufficient.
