Offshore wind farms could help capture carbon from air and store it long-term – using energy that would otherwise go to waste

Off the Massachusetts and New York coasts, developers are preparing to build the United States’ first federally approved utility-scale offshore wind farms – 74 turbines in all that could power 470,000 homes. More than a dozen other offshore wind projects are awaiting approval along the Eastern Seaboard.

By 2030, the Biden administration’s goal is to have 30 gigawatts of offshore wind energy flowing, enough to power more than 10 million homes.
