Sub-Zero DEU2450CI

The Sub-Zero DEU2450CI never switches off, and its certified 408 kWh a year works out to about $75 on a U.S.-average electric bill — roughly $6.24 a month for an average continuous draw of 47 watts. It sits near the bottom of the certified table — using 66% more than the median compact refrigerator (rank 1634 of 1645) — so the state you live in matters more than usual. The same unit costs $53 a year in Nevada but $215 in Hawaii — electricity rates, not the appliance, make the difference.
