The Association of Home Appliance Manufacturers (AHAM) has released data that reflect a decrease in home appliance energy consumption since 2000. Data from 2007 shipments of appliances show that refrigerators, dishwashers, and washing machines account for a 43% combined decrease in energy consumption since 2000. 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%. According to AHAM, the average refrigerator sold today consumes less energy than a 60-watt light bulb left on 24 hours per day.

Replacing older, inefficient appliances with more modern appliances provides a way for homeowners to save energy, especially if they purchase Energy Star–designated appliances.

"Appliance manufacturers have shown a commitment to efficiency that goes well beyond adherence to federal efficiency standards," said Joseph M. McGuire, president of AHAM, in a press release. "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."

AHAM is a trade association representing manufacturers and suppliers of major, portable, and floor-care home appliances. The association’s Energy Efficiency and Consumption Trends reports are available for purchase on the AHAM Web site.
