Full-sized chest freezers (Type 10)6 were again the most popular type in 2007, accounting for 39.4 percent of all freezers shipped in Canada. However, their market share declined from 64.9 percent in 1990, in favour of the other types, as shown in Table 3.7

In 1990, almost all freezers required more than 50 kilowatt hours (kWh) per year to freeze each cubic foot (cu.ft) of space. As shown in Table 4, by 2007, all freezers required less than 50 kWh per year to freeze each cubic foot of space, and 74.2 percent of them consumed less than 40 kWh per cu.ft per year.

Figure 5 shows how much energy freezers might have consumed annually between 1992 and 2007 without the decrease in average annual unit energy consumption (top line) and how much energy freezers actually consumed during those years (bottom line). The divergence of the two lines represents incremental annual energy savings.
On average, freezers consumed 0.06 petajoules (PJ) less per year than they would have without the contributing factors described in the Foreword. In 2007, freezers consumed approximately 0.07 PJ less than they would have without these factors. That amount is the equivalent of one year’s energy for approximately 600 households.
In 2007, cumulative energy savings for freezers reached 0.86 PJ (238.88 million kWh). Dollar savings for the study period were estimated to be $23 million (calculated at 9.5 cents/kWh).

7 Because of restrictions in the market information available, the freezer shipment data are not as comprehensive as those for the other appliances and should be used with caution.
