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 says. “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 says 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. Officials say 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 says.   ...read more read less
