US has taken FARC off its terrorist list, giving insight into Biden’s foreign policy

The U.S. had seven operating offshore wind turbines with 42 megawatts of capacity in 2021. The Biden administration’s goal is 30,000 megawatts by 2030. AP Photo/Michael Dwyer

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

Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.
