In North Carolina, home electricity runs 14.9¢/kWh — put a 2026 Volvo EX30 Twin Performance's EPA-rated 31.1 kWh/100mi against that and 100 miles costs $4.63, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 71.1% less than gas per mile, here specifically.
