Energy Efficient Appliances

Jump to Comments

The average Canadian home contains most of the six major appliances, which are: a refrigerator, freezer, dishwasher, range, clothes washer, and clothes dryer. In this average home, the appliances are responsible for 23% of all home energy consumption (Howell, 2008).

Natural Resource Canada’s Office of Energy Efficiency shows the average amount of energy used by each of these appliances (Natural Resources Canada, 2009):

Figure 1 – Average Annual Unit Energy Consumption for Selected Years

Using 1990 as a baseline, appliances in the average home in Canada used 5,789 KWH of energy annually:

Appliance Energy Consumption in KWH/year
Refrigerators 956
Freezers 714
Dishwashers 1026
Electric ranges 772
Clothes Washers 1218
Clothes Dryers 1103
Total 5789

Energy consumption can be reduced significantly through the use of Energy Star appliances. The following provides an example of what could be accomplished using some of the more highly rated appliances available (U.S. Environmental Protection Agency):

Appliance Energy Consumption in KWH/year Energy Star
Brand/Model
Refrigerators 387 GE/GTK181BX
Freezers 435 Kenmore/15202
Dishwashers 279 Jenn-Air /JDB3200AW
Electric ranges 772 *
Clothes Washers 191 GE/WPDH8910K
Clothes Dryers 905 *
Total 2969

* Electric ranges and clothes dryers are not rated as part of the Energy Star program because there is little difference in energy use among models. We have used the Natural Resources Canada energy use statistics for 2006.

Using more efficient appliances (Energy Star where applicable) can result in a 49% decrease in energy use. When you purchase new appliances or replace your existing appliances, close consideration should be given to purchasing the most energy efficient EnergyStar rated appliances.
