Figure 1 depicts the cumulative energy savings due to the above factors, measured in petajoules, of the six major household appliances from 1992 to 2007.
Figure 2 illustrates the significant increase in the penetration rate of ENERGY STAR® qualified appliances since they began appearing on the market in early 1999. By 2007, 76.2 percent of all dishwashers, 58.4 percent of all clothes washers and 44.3 percent of all refrigerators shipped in Canada were ENERGY STAR qualified products. Shipments of ENERGY STAR dishwashers decreased slightly once again in 2007, due to the increase in the stringency of the ENERGY STAR specification of dishwashers, which came into effect in January 2007.
Figure 3 compares the average annual unit energy consumption (UEC) of the six major household appliances in 1990 and 2007. The largest decrease in average annual UEC was in clothes washers, which experienced a 76 percent reduction, followed by dishwashers at 65 percent.
