Avanti RMS551SS

Running around the clock, the Avanti RMS551SS uses a certified 338 kWh per year — about $62 at the U.S. average rate, or $5.17 a month, the equivalent of a steady 39-watt draw. It sits near the bottom of the certified table — using 37% more than the median compact refrigerator (rank 1480 of 1645) — so the state you live in matters more than usual. The same unit costs $44 a year in Nevada but $178 in Hawaii — electricity rates, not the appliance, make the difference.
