Electricity price is the state-wide average residential rate from the U.S. Energy Information Administration, Electric Power Monthly table 5.6.A (May 2026). Your own utility's rate — and any time-of-use plan you are on — can differ substantially. Energy use per 100 miles is derived from EPA ratings; see any car's page for the method.
