 bsolute Growth in Commercial Sector Emissions
Figure 6 summarizes absolute
growth in carbon emissions by end-use from 1990 to 2010 for the commercial sectors.
The striking result from the graph is that miscellaneous
electricity is projected to contribute about two-thirds of the net growth in carbon
emissions in the cmmercial sector from 1990-2010. This result follows from
the relatively large base year emissions for this end-use combined with
high annual growth rates.
While growth in many end-uses has been reduced or eliminated
by efficiency standards, utility programs, and other government policies,
growth in miscellaneous electricity use has traditionally been ignored.
This end-use is often treated as an afterthought in even the most detailed
bottom-up analyses, in large part because of its complexity. Because it
is the category containing previously unknown uses for electricity, understanding
it requires constant attention to market data and a deep appreciation for
the subtleties of end-use analysis. |
