Thermador T24IF900SP

Running around the clock, the Thermador T24IF900SP uses a certified 443 kWh per year — about $83 at the U.S. average rate, or $6.95 a month, the equivalent of a steady 51-watt draw. Efficiency-wise it's unremarkable in a good way: within 1% of the median certified upright freezer (rank 225 of 431). The same unit costs $55 a year in North Dakota but $207 in Hawaii — electricity rates, not the appliance, make the difference.
