Before you install a home charger in Hawaii
The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Where these figures come from
The methodology guide names the exact EIA and EPA tables behind this page's numbers. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
