KOOLMORE RERFDSS-22C

Running around the clock, the KOOLMORE RERFDSS-22C uses a certified 588 kWh per year — about $111 at the U.S. average rate, or $9.23 a month, the equivalent of a steady 67-watt draw. Efficiency-wise it's unremarkable in a good way: within 5% of the median certified bottom-freezer refrigerator (rank 883 of 1458). The same unit costs $73 a year in North Dakota but $274 in Hawaii — electricity rates, not the appliance, make the difference.
