The Natural Resources Defense Council estimates a typical refrigerator accounts for around 10 to 15% of an entire household’s energy usage every single month. If you’re going away for an extended period of time, one of the best things you can do is power off your refrigerator. After it’s emptied out, simply flip the switch in the circuit breaker box to shut off the power. If this isn’t possible, the next-best thing is to increase the fridge temperature to 42 degrees. That’s cool enough to preserve food and get maximum energy efficiency.
