Reasons to switch in Hawaii
- ✓ Save $329/year on fuel at 44.3¢/kWh
- ✓ ~$600/year less in maintenance (no oil changes, fewer brake jobs)
- ✓ Solo HOV lane access — saves time during rush hour
- ✓ Strong public charging network in Hawaii
- ✓ Home charging overnight = never stop at a gas station
Things to consider first
- ! EVs typically cost $3,000–$6,000 more than comparable gas cars upfront
- ! Needs a place to charge at home — apartment renters face more friction
- ! Electricity at 44.3¢/kWh is above the national average — narrows the fuel savings gap
- ! Road trips require more planning around fast-charger availability
- ! Federal EV tax credit ended September 2025 — pricing now matters more
