Appliance Energy Use CalculatorLook for the ENERGY STAR® and EnergyGuide labels DishwasherCheck the manual that came with your dishwasher for the manufacturer's recommendations on water temperature; many have internal heating elements that allow you to set the water heater to a lower temperature. Scrape off, don't rinse off, large food pieces and bones. Soaking or prewashing is generally only recommended in cases of burned-on or dried-on food. Be sure your dishwasher is full, but not overloaded. Don't use the "rinse hold" function on your machine for just a few soiled dishes. It uses 3 to 7 gallons of hot water each time you use it. Let your dishes air dry. If you don't have an automatic air-dry switch, turn off the control knob after the final rinse and prop the door open a little so the dishes will dry faster. Refrigerator / Freezer Look for a refrigerator with automatic moisture control. Models with this feature have been engineered to prevent moisture accumulation on the cabinet exterior without the addition of a heater. This is not the same thing as an "anti-sweat" heater. Models with an anti-sweat heater will consume 5% to 10% more energy than models without this feature. Don't keep your refrigerator or freezer too cold. Recommended temperatures are 37 to 40 degrees F for the fresh food compartment of the refrigerator and 5 degrees F for the freezer section. If you have a separate freezer for long-term storage, it should be kept at 0 degrees F. To check the refrigerator temperature, place an appliance thermometer in a glass of water in the center of the refrigerator. Read it after 24 hours. To check the freezer temperature, place a thermometer between frozen packages. Read it after 24 hours. Regularly defrost manual-defrost refrigerators and freezers. Frost buildup increases the amount of energy needed to keep the motor running. Don't allow frost to build up more than one-quarter of an inch. Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper or a dollar bill so that the paper or bill is half in and half out of the refrigerator. If you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing. Cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder. Move your refrigerator away from the wall and vacuum the condenser coils once a year unless you have a no-clean condenser model. Your refrigerator will run for shorter periods with clean coils. Stoves / Ovens If you need to purchase a gas oven or range, look for one with an automatic, electric ignition system. An electric ignition saves gas because a pilot light is not burning continuously. In gas appliances, look for blue flames. Yellow flames indicate the gas is burning inefficiently and an adjustment may be needed. Consult your manufacturer or your local utility. Keep range-top burners and reflectors clean. They will reflect the heat better, and you will save energy. Use a covered kettle or pan to boil water. It is faster and it uses less energy. Match the size of the pan to the size of the heating element. If you cook with electricity, turn the stovetop burners off several minutes before the allotted cooking time. The heating element will stay hot long enough to finish the cooking without using more electricity. The same principle applies to oven cooking. Use small electric pans or toaster ovens for small meals rather than your large stove or oven. A toaster oven uses a third to half as much energy as a full-sized oven. Use pressure cookers and microwave ovens whenever it is convenient to do so. They can save energy by significantly reducing cooking time. Washer / Dryer Wash your clothes in cold water using cold-water detergents whenever possible. Wash and dry full loads. If you are washing a small load, use the appropriate water-level setting. Dry towels and heavier cottons in a separate load from lighter-weight clothes. Don't over-dry your clothes. If your machine has a moisture sensor, use it. Clean the lint filter in the dryer after every load to improve air circulation. Use the cool-down cycle to allow the clothes to finish drying with the residual heat in the dryer. Periodically inspect your dryer vent to ensure it is not blocked. This will save energy and may prevent a fire. Manufacturers recommend using rigid venting material, not plastic vents that may collapse and cause blockages.
