The US Department of Energy's ENERGY STAR Program has measured energy efficiency for washing machines and other major appliances, TVs, VCRs, heating and cooling equipment, residential light fixtures, office equipment, windows, and newly built homes. These products were tested for energy efficiency and operational cost factors. See www.energystar.gov/products for Energy Star products, retail stores selling them, and other related information.
Most of the energy used by a dishwasher goes toward heating the water which accounts for approximately 80% of the total energy used. Models that use less water use less energy. There are also several other factors that affect the energy use of dishwashers:
Buying a New Dishwasher
Installing A Dishwasher
When installing a dishwasher, try to locate it away from the refrigerator. Dishwashers produce heat during operation which, if placed too close to a refrigerator, will increase its energy consumption. If it is not possible to locate the dishwasher away from the refrigerator, you may be able to add extra insulation to the top, sides, and back when it is installed. This will both save energy and reduce noise levels.
