Liebherr UF3651
The Liebherr UF3651 never switches off, and its certified 155 kWh a year works out to about $29 on a U.S.-average electric bill — roughly $2.43 a month for an average continuous draw of 18 watts. Only a handful of certified compact freezers do better: it ranks 2 of 128 and undercuts the median by 37%. The same unit costs $19 a year in North Dakota but $72 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
