Did you know that your friendly refrigerator has a voracious energy appetite? It is, by far, the single biggest consumer of electricity in the average household, responsible for 10-15 percent of the electricity you use each month.
Older refrigerators, as a rule, are far less efficient than the newest ones—as much as 50 percent more efficient in many cases. But buying a brand-new, energy-efficient refrigerator is almost certainly not in the cards for most of us. Fortunately, other things will help.
Don’t set the thermostat too high. Even 1 degree will make a big difference.
If your refrigerator is near a heating vent, or always in the sun, then change the location, cover up the heat vent near it or drape the window.
Turn on your “energy saver” switch near the thermostat.
Clean the condenser coil. This one, very simple thing can improve the efficiency of your refrigerator by a third!
Get rid of your second refrigerator. If you don’t need it, don’t waste the energy.
Make sure the doors seal properly, and keep the cool in.
