Energy Star Appliances Help Consumers and Environment Auburn, March 15,2003---Energy Star-labeled appliances save consumers money and use less electricity and water than other appliances, says Barbara Mobley, an Extension money management specialist. The Energy Star rating label may be found on clothes washers, refrigerators, dishwashers and room air-conditioners. An appliance receives the Energy Star rating if it is significantly more energy efficient than the minimum federal standards. Some Energy Star appliances exceed the minimum standards by as much as 20 percent. “Although Energy Star models sometimes cost more to purchase initially, any extra up-front costs can often be made up with savings on utility bills,” Mobley says. Energy Star clothes washers use superior designs that require less water to get clothes thoroughly clean. These machines use sensors to match the hot water needs to the load, preventing energy waste. The savings include using 30 to 40 percent less energy per load, less wear and tear on clothes and better water extraction, meaning less dryer time. A typical household does nearly 400 loads of laundry a year, using about 40 gallons of water per full load with a conventional washer. In contrast, a full size Energy Star washer uses 20 to 25 gallons per load. Consumers could save as much as 7,000 gallons of water per year. In addition, the savings of all the energy that would have been needed to heat the water, adds up to savings for the consumer and the environment. The refrigerator is the single biggest power consumer in most households. A typical refrigerator made around 1990 uses about 900 kilowatt hours per year – that’s the same amount of energy you would use by leaving a 1,250 watt hair dryer on for a month! And the older a refrigerator is, the more power it burns. Energy Star refrigerator manufacturers use a number of advanced features to save energy such as better insulation, more efficient compressors, improved heat transfer surfaces, and more precise temperature and defrost mechanisms. Energy Star dishwashers save by using improved technology for the primary wash cycle and less hot water to clean. Construction includes energy-efficient motors and other advance technology such as sensors that determine the length of the washing cycle and the temperature of the water necessary to clean the dishes. Air-conditioners with Energy Star feature high efficiency compressors, fan motors and heat transfer surfaces. In an air-conditioner, the air is cooled when it passes over the refrigerant coils, which have fins, similar to an automobile radiator. The compressor sends the cooled refrigerant through the coils, and air cools as it is forced over the coils. By using advanced heat transfer technologies, more of the heat from the air is transferred into the coils than in conventional models, saving energy required to compress the refrigerant. It is important to buy an air-conditioner that is the correct size for the room, Mobley says. Air- conditioners remove heat and humidity from the air. Humidity is removed when the air in a room passes over the cooling coils of an air conditioner. If the unit is too large, it will cool the room quickly but only remove a portion of the humidity. This leaves the room with a damp, clammy feeling, since the air will not have circulated enough. A properly sized unit will remove humidity effectively as it cools. Running a smaller unit for a longer time will use less energy to completely condition a room than running a larger unit for a shorter time. Energy Star appliances are carried by retailers nationwide, says Mobley. Source: Barbara Mobley, a Money Management Specialist with the Alabama Cooperative Extension System.
