Hawaii home charging cost for the 2026 Honda Prologue AWD

A 2026 Honda Prologue AWD draws 34.1 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $15.66 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a little less than gas here: 2.3% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Honda Prologue AWD costs roughly $2,348 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $54 a year.

Cost of a full charge

Covering the 2026 Honda Prologue AWD's EPA-rated 294-mile range takes about 100.2 kWh, which costs about $46.03 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 20,068 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Honda Prologue AWD alone ranks 127 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Next step: home charger installation

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.
