2026 Volvo EX40 Twin: home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Volvo EX40 Twin's EPA-rated 36 kWh/100mi against that and 100 miles costs $16.53, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 3.2% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. 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.
