What energy costs in Hawaii, by category: the freshest reading (residential electricity, April 2026), the latest full-year prices for each fuel, and every fuel charted since 1980. Annual figures are in dollars per million Btu — one denominator, so a kilowatt-hour, a therm and a gallon can sit on the same axis honestly.
| Category | 2024 | 2014 | 10-yr | US 2024 | vs US |
|---|---|---|---|---|---|
| Electricity (residential) | $126 | $109 | +16% | $48.30 | +160% |
| Gasoline (all sectors) | $39.30 | $33.69 | +17% | $27.33 | +44% |

A million Btu is a fixed amount of heat (≈ 293 kWh of electricity, ≈ 10 therms of gas, ≈ 7.2 gallons of gasoline), so these prices compare fuels per unit of energy delivered, before equipment efficiency. "—" means the state has too little of that fuel's market for the EIA to price it.
