How we calculated this

For each state we compute the annual running cost of a washing machine using its nameplate 500 W, 1 hours/day, 300 days/year. States are ranked by total annual cost.

State electricity prices come from the U.S. Energy Information Administration’s Electric Power Monthly, Table 5.6.A (June 2026). See our methodology for the full formula.
