The Defense Department will install solar panels on the Pentagon, part of the Biden administration’s plan to promote clean energy and “reestablish the federal government as a sustainability leader.”

The Pentagon is one of 31 government sites that are receiving $104 million in Energy Department grants that are expected to double the amount of carbon-free electricity at federal facilities and create 27 megawatts of clean-energy capacity while leveraging more than $361 million in private investment, the Energy Department said.

The solar panels are among several improvements set for the Pentagon, which also will install a heat pump system and solar thermal panels to reduce reliance on natural gas and fuel oil combustion systems
