Energy-efficiency doesn’t come cheap, but the Fenty administration wants to be the banker that makes it happen for D.C. property owners.

The District has applied for a U.S. Department of Energy grant of $35 million that it would lend to homeowners and commercial property owners for energy-efficiency improvements like new storm windows and doors, solar panels or light fixtures. The plan also involves the sale of up to $250 million in bonds, though the city wouldn’t be on the hook for the debt.
