There’s just one offshore wind farm generating electricity in the United States, but things are quickly changing. Several huge wind projects along America’s Eastern Seaboard are already in various stages of development, and the industry is also set to get a multi-billion-dollar boost from the Infrastructure Investment and Jobs Act, passed last year.

But placing wind turbines far off the coast is just one part of the engineering problem. Operators also need an efficient way to bring the electricity they generate to consumers on land.
