The Trump administration suspended leases on Monday for five large offshore wind projects that are under construction off the U.S. East Coast over what it called national security concerns, sending shares of offshore wind companies plunging. The suspension was the latest blow for offshore wind developers that have faced repeated disruptions to their multi-billion-dollar projects under U.S. President Donald Trump, who has said he finds wind turbines ugly, costly and inefficient. State officials, Democratic lawmakers, offshore wind companies, and industry trade groups slammed the move as unjustified.

The U.S. Department of the Interior said the decision was the result of complaints by the Pentagon that the movement of huge turbine blades for offshore wind projects, as well as the highly reflective towers that hold them up, cause radar interference that can make it hard to identify and locate security threats. The pause will give relevant federal agencies “time to work with leaseholders and state partners to assess the possibility of mitigating the national security risks posed by these projects,” the department said in a statement. “The prime duty of the United States government is to protect the American people,” Secretary of the Interior Doug Burgum said in the statement.
