The State of Energy Efficiency in Canada, Office of Energy Efficiency Report 2006
The State of Energy Efficiency in CanadaThe Office of Energy Efficiency (OEE) has become Canada's foremost centre for collecting and analysing energy efficiency data, analysing trends in energy use and developing and delivering key programs that promote energy efficiency in the major energy-using sectors of the economy. One of its goals is to improve Canada's ability to track the influence of its energy efficiency programs on market trends and identify opportunities to further improve energy efficiency. At the core of the OEE's analytical capacity is its annual assessment of trends in energy use and related greenhouse gas (GHG) emissions in Canada since 1990. The results are published in the technical report Energy Efficiency Trends in Canada. Changes in energy efficiency cannot be measured directly at the sectoral or economy-wide level. Thus, to track changes in energy efficiency, the OEE uses a factorization methodology to develop the OEE Energy Efficiency Index,³ the only one of its kind in Canada. The OEE Index depicts annual changes in energy efficiency in the Canadian economy. Note that the OEE Index is only an estimate of changes in energy efficiency in the economy. Even after accounting for the other principal factors that influence energy intensity, namely activity, weather, structure and service level, the resulting estimate of energy efficiency includes some factors not related to efficiency. For example, the estimate of industrial energy efficiency will include the effect of changes in sub-sector mixes of products or in the products themselves. The OEE Index shows that, even with the many barriers to improvement in energy efficiency, strong and measurable progress has been made, due in part to the programs of the OEE. For 1990-2003, the OEE Index shows an increase in value, indicating that energy efficiency improved by 13 percent (see Figure 3). As a result of this improvement, Canadians saved approximately $13.4 billion in energy costs in 2003 alone. Energy use increased between 1990 and 2003. Without improvements in energy efficiency, increases attributable to activity, weather, structure and service level would have led to an increase of 32 percent. However, as a result of a 13 percent improvement in energy efficiency, actual energy use increased by 22 percent (see Figure 4). Each of the four principal end-use sectors in the Canadian economy (residential, commercial/institutional, industrial and transportation) contributed to this improvement in energy efficiency. The following are a few highlights from the analysis:
