An energy-efficient mortgage, or EEM, helps homeowners finance energy-efficient homes or renovations. When financing a renovation, the cost of energy-efficient upgrades is rolled into your mortgage payment. That means you can enjoy lower utility bills sooner, instead of waiting to tackle energy-saving projects over time.

EEMs are available when buying a home or refinancing your existing mortgage. You can also use an EEM to buy a home with existing energy-efficient features. NerdWallet picked some of the best energy-efficient mortgage lenders in a variety of categories so you can determine which one is right for you.
