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.
Energy Star labeled clothes washers use 35-50% less water, and up to two-thirds less energy that conventional washers. The average family can save up to $100 each year in costs by switching to an Energy Star labeled clothes washer.
Use kitchen, bath, and other ventilating fans wisely. Turn these fans off as soon as they are no longer needed. In about 1 hour, these fans can pull out a house-full of warmed or cooled air.
Don't keep your refrigerator or freezer too cold. Recommended temperatures are 37° to 40°F for the fresh food compartment of the refrigerator and 5°F for the freezer section. If you have a separate freezer for long-term storage, it should be kept at 0°F.
When using a clothes dryer, separate your clothes and dry similar types of clothes together. Lightweight synthetics, for example, dry much more quickly than bath towels and natural fiber clothes.
When shopping for a dishwasher, look for features that will reduce water use, such as booster heaters and smart controls. Ask how many gallons of water the dishwasher uses during different cycles. Dishwashers that use the least amount of water will cost the least to operate.
To check 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.
Dry two or more loads of clothes in a row, taking advantage of the dryer's retained heat.
When shopping for a clothes washer, look for the following design features that help clothes washers cut water usage: water level controls, "suds-saver" features, spin cycle adjustment, and large capacity. For double the efficiency, buy an Energy Star unit.
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.
