Gaggenau RW204770

Running around the clock, the Gaggenau RW204770 uses a certified 100 kWh per year — about $19 at the U.S. average rate, or $1.57 a month, the equivalent of a steady 11-watt draw. That's 30% less than the median certified compact-cooler refrigerator, placing it comfortably in the efficient third of the field (15 of 81). The same unit costs $12 a year in North Dakota but $47 in Hawaii — electricity rates, not the appliance, make the difference.
