SAPPHIRE SW243DZSSPR

Running around the clock, the SAPPHIRE SW243DZSSPR uses a certified 135 kWh per year — about $25 at the U.S. average rate, or $2.12 a month, the equivalent of a steady 15-watt draw. Efficiency-wise it's unremarkable in a good way: within 6% of the median certified compact-cooler refrigerator (rank 30 of 81). The same unit costs $17 a year in North Dakota but $63 in Hawaii — electricity rates, not the appliance, make the difference.
