Is Electrification Worth It in Hawaii?

Hawaii doesn't need heat pumps. You need AC and solar.

Honolulu gets 0 heating degree days and pays $0.33/kWh for electricity—highest in the nation. You run AC year-round in most homes. Hawaiian Electric has terrible net metering (they stopped accepting new solar interconnections for years), but rooftop solar still makes sense because retail electricity is so expensive.

Install a high-efficiency mini-split AC system for cooling. Add solar with battery storage to cut your bills from $350/month to under $100/month. The payback is 6-9 years even with Hawaii's difficult utility policies. Heat pumps as a category don't matter here—you're buying AC with a heating feature you'll never use.
