Kenmore 7931

The Kenmore 7931 never switches off, and its certified 553 kWh a year works out to about $104 on a U.S.-average electric bill — roughly $8.68 a month for an average continuous draw of 63 watts. Efficiency-wise it's unremarkable in a good way: within 2% of the median certified bottom-freezer refrigerator (rank 686 of 1458). The same unit costs $68 a year in North Dakota but $258 in Hawaii — electricity rates, not the appliance, make the difference.
