1. Let your dishes air dry. A dishwasher uses more energy to dry dishes than to wash them. If your dishwasher doesn't have an automatic air-dry switch, turn off the control knob after the final rinse and prop the door open to let moisture escape.
2. When purchasing a dishwasher, look for energy saving features such as a short wash cycle. Shorter washing cycles, with fewer rinses, save water and water-heating energy.
3. Use your dishwasher only for full loads. Be sure your dishwasher is full, but not overloaded when you turn it on. Improper loading can result in poorly cleaned dishes that need to be rewashed.
4. Keep your refrigerator and freezer filled for most economical operation. Less cold air is lost when the door is opened in a filled refrigerator because the food helps retain the cold.
5. Adjust refrigerator settings to 37° F - 40° F and freezer settings to 0° F - 5° F. To check the temperature of your refrigerator or freezer, place an outdoor or refrigeration thermometer on the middle shelf or in the center overnight. In the morning, adjust the settings if necessary and check it again until correct.
6. Clean refrigerator coils twice a year, more often if you have pets. Condenser coils are located at the bottom or rear of your refrigerator. If they are allowed to accumulate dust and dirt as much as 25 percent more energy is required to maintain proper temperature.
7. Allow foods to partially cool before placing them in the refrigerator. It takes more energy to cool hot food. For added savings, cover foods and liquids. The moisture that is released by uncovered containers increases energy use during the refrigerator's defrost cycle.
8. If you have a freezer or second refrigerator that is nearly empty, turn it off. Use second appliances only when necessary or have them removed.
9. Install your dishwasher away from your refrigerator. The dishwasher's heat and
moisture make the refrigerator work harder. Keep your refrigerator away from other heat sources such as direct sunlight.
10. Select a refrigerator with a freezer on top. A side-by side unit uses up to 20 percentmore energy. The Energy Guide label will help you choose the most efficient model.
