## What to know about the Hawaii numbers

- **Rebates not checked yet**: We haven't checked heat pump rebates in Hawaii yet, so the numbers here leave them out. Utility and state programs can take thousands off a heat pump, so ask your utility and your contractor what's available.
- **Little heating need**: Most of Hawaii needs almost no heating and few homes have a furnace, so the comparison here is mostly about cooling. Hawaii's gas is synthetic gas or propane at prices well above the mainland.
- **Some average prices**: 59% of Hawaii ZIP codes here are priced on a current utility tariff; the rest use the utility's average price from the U.S. Energy Information Administration (about two years old). Each utility page says which.
- **Regional fuel prices**: EIA doesn't publish a Hawaii price for every fuel: propane uses the national average and heating oil uses the national average. Enter your own price if you heat with it.
