WASHINGTON (AP) — The Trump administration said Monday it is pausing leases for five large-scale offshore wind projects under construction in the East Coast due to unspecified national security risks identified by the Pentagon.

The pause is effective immediately and will give the Interior Department, which oversees offshore wind, time to work with the Defense Department and other agencies to assess the possible ways to mitigate any security risks posed by the projects, the administration said.

“The prime duty of the United States government is to protect the American people,” Interior Secretary Doug Burgum said in a statement. “Today’s action addresses emerging national security risks, including the rapid evolution of the relevant adversary technologies, and the vulnerabilities created by large-scale offshore wind projects with proximity near our east coast population centers.”

The administration confirmed that leases are paused for the Vineyard Wind project in Massachusetts, Revolution Wind in Rhode Island and Connecticut, Coastal Virginia Offshore Wind, and two projects in New York: Sunrise Wind and Empire Wind.

The Interior Department cited concerns regarding radar interference caused by the massive turbine blades and reflective towers, which create 'clutter' that could obscure legitimate targets.

This pause follows just two weeks after a federal judge ruled against Trump’s executive order that sought to block wind energy projects, deeming it arbitrary and unlawful. This ruling came as a victory for a coalition of state attorneys general challenging the legality of the halt on wind leasing.

Trump has consistently shown hostility towards renewable energy initiatives like offshore wind, favoring fossil fuel projects instead, raising concerns among environmentalists about the future of sustainable energy development in the U.S.
