Chapter 4 / Electric Ranges

Table 6 illustrates that in 1990, the electric ranges that dominated the market (81.9 percent) consumed more than 750 kilowatt hours (kWh) per year. In 2003, there was a considerable increase in the market share of electric ranges that consumed less than 600 kWh, reaching 90.2 percent in 2007. This change is due to a new energy-consumption standard introduced in October 2003.9

4.1 Energy Savings

Figure 7 shows how much energy might have been consumed by electric ranges without the minimum energy performance standards (MEPS) or the new energy-consumption standard (top line) and how much energy they actually consumed (bottom line).

Annual Energy Savings for Electric Ranges, 1992–2007.

The gap between the two lines represents incremental annual energy savings – on average, 0.02 petajoules (PJ) less per year from 1992 to 2002 and 0.45 PJ per year from 2003 to 2007. The total savings for electric ranges for 2007 (0.70 PJ) is the equivalent of one year’s energy for approximately 6300 households.

In 2007, cumulative energy savings for electric ranges reached 2.41 PJ (669 million kWh). Dollar savings for electric ranges for the study period were estimated to be $64 million (calculated at 9.5 cents/kWh).

9 Testing to the new standard resulted in a lower EnerGuide rating in kWh per year compared with previous years. Several important changes were made to the calculation of the rating. The changes include a reduction in the number of times the self-cleaning is used – from 11 times per year to 4 – and usage factors that include a decrease in the use of these appliances. Note that this decrease in the EnerGuide rating is not an indication of a better-performing cooking appliance.
