The United States government has paused five major offshore wind projects along the east coast, citing national security concerns related to radar interference and the potential vulnerability of key population centers. The Department of the Interior highlighted the risks posed by evolving adversary technologies and the clutter created by large-scale wind farms, which could make it harder to distinguish real threats in the airspace. The decision has sparked alarm among renewable energy companies and state leaders, who warn that the move could disrupt clean energy jobs and increase electricity prices in the region. Share prices for companies involved in the projects, including Dominion Energy and Orsted, fell sharply following the announcement. The pause comes amid ongoing legal and political battles over the future of wind energy in the United States, as demand for power continues to grow.
