The US Department of Interior paused leases on all five offshore wind projects currently under construction, citing classified national security risks identified by the Department of Defense. The affected projects include major installations off Virginia, New York, Connecticut, Rhode Island, and Massachusetts, some nearly complete with significant infrastructure already in place. This move follows the Trump administration's broader opposition to offshore wind power, despite previous court rulings that found no substantive reasons for blocking these projects. Affected states and companies are preparing legal challenges to contest this decision.
