Whirlpool WRT549SZD

The Whirlpool WRT549SZD never switches off, and its certified 378 kWh a year works out to about $69 on a U.S.-average electric bill — roughly $5.78 a month for an average continuous draw of 43 watts. Efficiency-wise it's unremarkable in a good way: within 4% of the median certified top-freezer refrigerator (rank 477 of 713). The same unit costs $50 a year in Nevada but $199 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
