Annual energy consumption for all major household appliances during the study period was significantly reduced, most likely due to the following factors: the significant research and development activities carried out by appliance manufacturers, improvements to the minimum energy performance standards (MEPS), the EnerGuide for Equipment program, the ENERGY STAR® Initiative and various incentives and rebates offered by the federal, provincial and municipal governments and utilities. Figure 7.1 shows the estimated annual energy consumption of major appliances between 1992 and 2005 without these factors as well as how much energy was actually consumed by major appliances during this period.
The gap between the two lines in Figure 7.1 represents incremental annual energy savings. Energy efficiency began to improve almost immediately after the Energy Efficiency Act came into force in 1992, thanks to market forces, such as the regulations expected from the Act and United States regulations.

The average annual energy savings for major appliances were estimated to be 2.34 petajoules (PJ) between 1993 and 2005. (No energy savings had been expected in 1992.) This indicates that, on average, major appliances consumed about 2.34 PJ less per year than they would have without the contributing factors.
The largest annual energy savings occurred in 2005, when major appliances consumed about 5.60 PJ less than they would have otherwise. Cumulative energy savings for major appliances are shown in Figure 7.2 and Table D.41 (in Appendix D, "Detailed Tables"). Because the energy saved in any given year accrues over time, cumulative energy savings grew steadily between 1992 and 2005. They reached a total savings of 30.48 PJ (8.47 billion kilowatt hours [kWh]) in 2005 (taking into account the life expectancy factor of the various appliances). That is the equivalent of a year's energy for about 274 000 households. It is estimated that these energy savings resulted in consumers saving approximately $779 million (or $60-$70 2005 dollars per household), calculated at 9.2 cents/kWh.36
Table 7.1 provides an overview of the average annual unit energy consumption for the six major household appliances for six years during the study period. It demonstrates a significant improvement in energy efficiency as evidenced throughout this report.
