The Trump administration has issued an order to stop construction on a major offshore wind project to power more than 500,000 New York homes, the latest in a series of moves targeting the industry.

Ms. Hochul and New Jersey’s governor, Phil Murphy, also a Democrat, have championed the development of offshore wind as a solution to their states’ rapidly growing demand for electricity. Their plans were critical components of the Biden administration’s goal of generating 30 gigawatts of offshore wind energy by 2030.

Trump officials ordered that work be halted immediately on Empire Wind, a major wind project off the coast of New York, dealing a blow to the industry.
