Liebherr HW 8000
The Liebherr HW 8000 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. That's 12% less than the median certified cooler refrigerator, placing it comfortably in the efficient third of the field (14 of 48). The same unit costs $19 a year in North Dakota but $72 in Hawaii — electricity rates, not the appliance, make the difference.
