Sub-Zero ID-36R

The Sub-Zero ID-36R never switches off, and its certified 230 kWh a year works out to about $42 on a U.S.-average electric bill — roughly $3.52 a month for an average continuous draw of 26 watts. Efficiency-wise it's unremarkable in a good way: within 7% of the median certified compact refrigerator (rank 715 of 1645). The same unit costs $30 a year in Nevada but $121 in Hawaii — electricity rates, not the appliance, make the difference.
