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

4  Electric Ranges

4.1   2003 Market Snapshot

In 2003, 55 percent of the electric ranges shipped in Canada were self-cleaning units. The shipment-weighted average annual unit energy consumption for self-cleaning ranges was 691 kilowatt hours (kWh), compared with 732 kWh for regular electric ranges. Even though the energy consumption rating takes into account the energy used during the self-cleaning cycles (based on 11 cleanings per year), these ranges use less energy than the regular electric ranges because their ovens are generally better insulated and the door seals are better than those in the non-self-cleaning ovens. This means that the self-cleaning units lose less heat through the oven door.

Electric ranges typically make up 92 percent of the market; gas ranges constitute the remainder.

4.2  Distribution of Shipments

4.2.1  Distribution by Type

In 1990, self-cleaning electric ranges accounted for less than one quarter (22.9 percent) of all electric ranges available on the market. By 2003, self-cleaning ranges had increased in popularity, with market share increasing to 55.1 percent. This represents a 32 percent increase since 1990, or an annual growth rate of 2.5 percent.

In contrast, the market share of electric ranges that were not self-cleaning decreased by 32 percent, dropping from 77.1 percent in 1990 to 44.9 percent in 2003.

Distribution of Electric Ranges by Average Annual Unit Energy Consumption for 2003

Between 1990 and 2003, there were limited but noticeable improvements in the energy efficiency of electric ranges. Before 1992, the ranges that dominated the market (42 percent) consumed between 800 and 849 kWh per year. In 2003, the market share of electric ranges in this category fell to 16.5 percent. By then, the ranges that dominated the market consumed between 700 and 799 kWh per year and enjoyed a 57.3 percent market share, an increase of 13 percent during the study period. In 2003, there was also a considerable increase (17.9 percent) in market share of ranges that consumed less than 600 kWh.

4.3  Energy Consumption

4.3.1  Average Annual Unit Energy Consumption by Model Year

Between 1990 and 2003, the energy consumption of electric ranges remained relatively unchanged. The decrease in average annual unit energy consumption, as illustrated in Figure 4.4, was about 1 percent, or 9 kWh. However, in 2003, the energy consumption decreased substantially, which is attributable to a new reference standard for electric ranges having been put into place in 2003, and this resulted in the reduction of the annual energy consumption for all models. This decrease may not reflect any improvement in energy efficiency of those models.

4.4  Energy Savings

Electric ranges were the only appliances that did not experience a notable decline in energy consumption following the introduction of the minimum energy performance standards (MEPS) in 1995.

Figure 4.5 shows that electric ranges consumed about the same amount of energy that they would have used without the MEPS or technological improvements.

FIGURE 4.5
Annual Energy Savings for Electric Ranges, 1992-2003*

* For greater detail, see Table C.10.

The average annual energy savings for electric ranges during 1993 to 2003 were estimated to be 0.04 petajoules (PJ). (No savings were expected for 1992.)

The cumulative energy savings for electric ranges are shown in Figure 4.6. Cumulative energy savings grew steadily between 1994 and 2003, as annual energy savings began to accrue. However, cumulative energy savings were still considerably smaller than those for other appliance types. Savings reached a total of 0.35 PJ in 2003, partly due to the new reference standard introduced in 2003.

To summarize, by 2003, self-cleaning ranges increased in popularity by 32 percent, with market share increasing to 55.1 percent. In 2003, the shipment-weighted average annual unit energy consumption for self-cleaning ranges was 691 kWh, compared with 732 kWh for regular electric ranges.

Between 1990 and 2003, there were limited but noticeable improvements in the energy efficiency of electric ranges. By 2003, the ranges that dominated the market consumed between 700 and 799 kWh (57.3 percent); whereas before 1992, those that dominated consumed between 800 and 849 kWh (42 percent). In 2003, there was also a considerable increase (17.9 percent) in market share of ranges that consumed less than 600 kWh.

Electric ranges were the only appliances that did not experience a notable decline in energy consumption following the introduction of the MEPS in 1995. The average annual energy savings for electric ranges were estimated to be 0.04 PJ between 1993 and 2003, with the largest annual energy savings occurring in 2003, at 0.16 PJ. This is due to the new reference standard for ranges put into place in 2003, as noted above. Total energy savings for the study period reached 0.35 PJ.
