A US court has ordered the restart of all offshore wind power construction, which was previously halted by the Trump administration due to claimed national security risks. The administration had cited a classified report as the reason for the halt, but judges found this justification to be unconvincing. The construction of five offshore wind projects was blocked, but the companies building them have now been granted temporary injunctions to continue work. The government can still appeal the decision, but the consistency of the rulings suggests it will likely fail.
