Thermador T36FT820N

Running around the clock, the Thermador T36FT820N uses a certified 570 kWh per year — about $107 at the U.S. average rate, or $8.94 a month, the equivalent of a steady 65-watt draw. Efficiency-wise it's unremarkable in a good way: within 1% of the median certified bottom-freezer refrigerator (rank 778 of 1458). The same unit costs $70 a year in North Dakota but $266 in Hawaii — electricity rates, not the appliance, make the difference.
