Save Money with Hawaii Energy’s Rebates.

Hawaii Energy’s cash rebates help you invest in energy-efficient equipment for your home. These installations quickly pay for themselves and the savings keep coming year after year.

Rebates are available to residential electric utility ratepayers on Hawaii Island, Lanai, Maui, Molokai and Oahu only. They are available on a first-come, first-served basis and are subject to availability of funds, restrictions, change and/or discontinuation without advance notice. Kauai residents are serviced by a utility cooperative and therefore not eligible for Hawaii Energy rebates. Please contact the Kauai Island Utility Cooperative for more information at (808) 246-4300.

Water Heating

Your home’s largest energy consumer is your electric water heater. When you switch to more energy-efficient options, you can save up to 40% on your electric bill. What’s more, with Hawaii Energy’s rebate combined with state and federal tax credits, you can save nearly 70% on the system purchase price in the first year.


Energy-efficient lighting like LEDs use up to 90% less energy to produce the same amount of light as old-fashioned, incandescent light bulbs and can last up to 20 years.


Switching out your appliances to energy-efficient models will help you save energy and reduce your monthly electric bills. Hawaii Energy offers you rebates to get rid of your old appliances as well as on the purchase of energy-saving appliances that are ENERGY STAR® qualified.

HVAC (Cooling)

As much as half of the energy used in your home goes to heating and cooling. Regular maintenance and exploring other energy-efficient cooling options can have a big effect on your energy savings, electric bill and comfort. Find out how to get our rebates for some cool savings.
