How to lower the cost of running a refrigerator

Your refrigerator is one of the few appliances that never turns off, but it doesn't draw its rated wattage all day. The compressor cycles on and off to hold temperature, running roughly 30–40% of the time in a typical kitchen. That is why we apply a duty cycle: a 150W fridge at 35% uses about 1.26 kWh a day. Older refrigerators (pre-2001) and second fridges in hot garages can use two to three times more.

  • Set the fridge to 37–40°F and the freezer to 0°F — colder settings waste energy.
  • Vacuum the condenser coils once or twice a year.
  • Retire an old second fridge in the garage — it can cost more per year than a new one.
