Thermador T24ID900LP

Running around the clock, the Thermador T24ID900LP uses a certified 457 kWh per year — about $86 at the U.S. average rate, or $7.17 a month, the equivalent of a steady 52-watt draw. Efficiency-wise it's unremarkable in a good way: within 4% of the median certified upright freezer (rank 257 of 431). The same unit costs $56 a year in North Dakota but $213 in Hawaii — electricity rates, not the appliance, make the difference.
