Samsung RS27T5561

Running around the clock, the Samsung RS27T5561 uses a certified 691 kWh per year — about $130 at the U.S. average rate, or $10.84 a month, the equivalent of a steady 79-watt draw. Efficiency-wise it's unremarkable in a good way: within 7% of the median certified side-by-side refrigerator (rank 83 of 116). The same unit costs $85 a year in North Dakota but $322 in Hawaii — electricity rates, not the appliance, make the difference.
