The Trump administration on Monday suspended 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 suspension, effective immediately, is the latest step by the administration 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 statement did not detail the national security risks. It called the move a pause, but did not specify an end date.
