The Biden administration has greenlighted the first major offshore wind project in federal waters, culminating a review process that saw delays and roadblocks during the Trump administration.

The Interior and Commerce departments authorized the construction of the Vineyard Wind project, an 800-megawatt wind project off the coast of Massachusetts, in a final record of decision on Tuesday. The project could begin delivering power to roughly 400,000 homes on the East Coast in late 2022.
