Wisconsin home charging cost for the 2026 Tesla Model S

In Wisconsin, home electricity runs 18.99¢/kWh — put a 2026 Tesla Model S's EPA-rated 27.1 kWh/100mi against that and 100 miles costs $5.15, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 67.8% less than gas per mile, here specifically.
