Your refrigerator accounts for anywhere from 10% to 18% of your electricity bill, if yours is an average American household.

That's a lot of power. If you don't plan to replace your refrigerator (hint: you can save big bucks if you do), be sure you're using the one you've got in an energy-wise way.

Unplug it. Recycle it. Too often we see old, inefficient refrigerators in people's garages driving up the electricity bill $100 to $400 or more per year just to store extra sodas. If that's the case for you, consider either replacing, unplugging, or just getting rid of it. Your electricity bill will thank you. If you decide to dispose of it, be sure to recycle it through a qualified recycler. Contact your town, utility, or waste collector. Older fridges use refrigerants that must be treated as toxic waste.

Set your refrigerator temperature between 35° to 38° F. Your refrigerator can use 25% more energy if it's set 10°F colder than recommended!

Set your freezer temperature to 32°F (0°C). There's no need to set your freezer to colder than the temperature it takes to freeze food and water. If your settings don't show you temperature ranges, use a thermometer to check temps. (An outdoor thermometer or a candy thermometer works.)

Check the door seal. Close a piece of paper or dollar bill halfway in the refrigerator or freezer door. If you can pull the paper out easily, the latch may be loose or it's time to replace the seal. Replacing the seal is difficult; it might be worthwhile to replace the refrigerator.

If possible, keep it in a cool location. Position your refrigerator away from heat sources like ovens, dishwashers, hot water heaters, or direct sunlight.

Keep the door closed. Opening the door frequently will increase your energy use.

Keep it full but not packed. The food actually helps hold the cold!

Defrost it occasionally. If your fridge's freezer is thick with iced-up condensation, it's working optimally. Defrost it at least once a year.
