Energy Consumption of Major Household Appliances Shipped in Canada – Trends for 1990-2003


7  All Major Appliances

7.1   Total Energy Savings

Annual energy consumption for all major household appliances during the study period was reduced likely as a result of two factors: an increase in general energy efficiency and the implementation of the minimum energy performance standards (MEPS). Figure 7.1 shows the estimated annual energy consumption of major appliances between 1992 and 2003 without these two factors, as well as how much energy was actually consumed by major appliances.

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 U.S. regulations.

The average annual energy savings for major appliances were estimated to be 1.89 petajoules (PJ) between 1993 and 2003. (No savings were expected in 1992.) This indicates that, on average, major appliances consumed about 1.89 PJ less per year than they would have without the MEPS set out in Canada’s Energy Efficiency Regulations and improved appliance technology.

The largest annual energy savings occurred in 2003, when major appliances consumed about 3.65 PJ less than they otherwise would have. Cumulative energy savings for major appliances are shown in Figure 7.2 and Table C.15. Since the energy saved in any given year accrues over time, cumulative energy savings grew steadily between 1992 and 2003. They reached a total savings of 20.75 PJ in 2003, the equivalent of a year’s energy for about 174 000 households.
