U.S. Department of Energy officials say they're optimistic the costs of offshore wind energy development will begin to ease by the end of the decade.

The U.S. may need 700 to 900 GW of clean, firm power to decarbonize the grid even as electricity demand increases, according to a new report from the Department of Energy.

The Department of Energy released a report outlining how to bring more virtual power plants online, which can be a money-saving way of helping to balance the grid and maintain resource adequacy.
