WASHINGTON — The Trump administration said Monday it is pausing leases for five large-scale offshore wind projects under construction along the East Coast due to what it said were national security risks identified by the Pentagon.
The pause, effective immediately, is the latest step the administration has taken to hobble offshore wind in its push against renewable energy sources. It comes two weeks after a federal judge struck down President Donald Trump's executive order blocking wind energy projects, calling it unlawful.
The administration said the pause 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 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 statement did not detail the national security risks.
Wind proponents slammed the move, saying it was another blow by the administration against clean energy.
The administration said leases are paused for the Vineyard Wind project under construction 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 said unclassified reports from the U.S. government have long found that the movement of massive turbine blades and the highly reflective towers create radar interference called ''clutter.'' The clutter caused by offshore wind projects obscures legitimate moving targets and generates false targets in the vicinity of wind projects, the Interior Department said.
