Technology Snapshot & Benefits:

Both immediate and indirect economic savings can come from energy-efficient appliances such as refrigerators, horizontal-axis washing machines, clothes dryers, dishwashers, etc. Immediate and continuing savings accrue from lower utility bills for electricity and/or water. The performance levels of these appliances meet, and generally exceed, those of industry standard models. As a case in point, consider household refrigeration. By the late 1970s, refrigerators reached their most inefficient performance by requiring about 1750 kiloWatt-hours per year to operate. Modern energy-efficient refrigerators provide the same or better service at 450-550 kiloWatt-hours per year, and they are much quieter in operation.

Appliances with relatively high operating efficiencies are usually more expensive to
purchase. However, higher efficiency appliances provide a measure of insurance against increases in energy prices, emit less air pollution, and are attractive selling
points when the home is resold. Home buyers should invest in high-efficiency appliances such as water heaters, clothes washers and dryers, dishwashers, and refrigerators especially if these appliances will be used a great deal. Because all major appliances must have an EnergyGuide label, read the label carefully to make sure you buy the most efficient appliance. To help you choose wisely, major appliances with an Energy Star label exceed the federal government's minimum efficiency standards.

The direct economic savings achieved by efficient appliances are a function of how much the appliance will be used, the performance level of the equipment being replaced, and local costs for utilities. When you replace older equipment, it is not uncommon for electricity consumption for that appliance to decrease by 50% or more. In general, if the appliance being replaced is more than 15 years old, and it is replaced with a state-of-the-art unit, you may expect utility savings of 20%-60% compared with the energy required by the previous appliance. Horizontal axis washing machines typically save consumers 50% in both electric and water utilities. Additional savings come from reduced quantities of detergent.

Your monthly electrical bill is for all electricity used by all electrical loads in the building, so changing a single appliance will lower the bill, but in proportion to the amount of electricity formerly used by that appliance. If refrigeration represents 15-20% of your electric bill, a new refrigerator that is twice as efficient as the unit being replaced will lower your total bill by about 7-10%.
