Refrigerators, dishwashers, and clothes washers account for a 43% combined decrease in energy consumption since 2000. The figure comes from the Association of Home Appliance Manufacturers (AHAM), which released new data based on 2007 shipments of major appliances. AHAM said that, from a global climate change perspective, the energy savings realized in 2007 shipments of refrigerators, dishwashers, and clothes washers would offset the CO2 emissions of more than 698 million gallons of gasoline consumed, or the annual CO2 emissions from 1.3 coal fired power plants.
Among the AHAM findings:
- Clothes washer energy consumption has decreased by 63% since 2000 while tub capacity has grown by 8%.
- Dishwasher energy consumption has dropped nearly 30% and water consumption has declined 29% since 2000.
- Refrigerator energy consumption has also decreased 30% since 2000 and efficiency, measured by a unit’s energy factor, has increased 39%. The average refrigerator sold today consumes less energy than a 60-watt light bulb left on 24 hours a day.
AHAM points out that home appliances have proven to be an effective way of reducing residential energy consumption. Replacing older, inefficient appliances with more modern appliances is one of the easiest ways for consumers to realize substantial home energy savings. Even greater savings can be obtained by purchasing Energy Star designated appliances.
According to Joseph M. McGuire, president of AHAM, “Appliance manufacturers have shown a commitment to efficiency that goes well beyond adherence to federal efficiency standards. Through additional investments in technology and consumer awareness, partnering with retailers, and promoting Energy Star, our industry has led the way in taking residential energy efficiency to the next level. This data shows that replacing older appliances can make a huge impact in a family’s energy budget.” Back
