Efficiency Maine’s Residential Programs support Mainers with energy improvements ranging from lighting upgrades to whole-house retrofits.
Upgrading to efficient light bulbs is an excellent way to start saving energy and Efficiency Maine discounts the price of energy efficient lighting at most major retailers. You can find a list of the best deals on energy efficient bulbs here.
Qualifying clothes washers and room air purifiers are each eligible for a $50 rebate. Heat pump water heaters are eligible for a $750 rebate. Incentives are also available for energy assessments, home insulation, and heating systems. Homeowners are eligible for up to $3,000 in rebates towards improving the efficiency of their home. You can also finance your energy efficiency project with an Energy Loan from Efficiency Maine.
Additional rebates and financing options may be available if you are a natural gas customer; click here for details.
