Thus through calculating the relative impact on energy use from changes in each of
these components, the impacts on energy use related to improved end-use energy
efficiency (reductions in energy intensities) can be isolated from changes derived
from shifts in the activity and structure components.
The resulting indices from each sector defined above can be combined further and
weighted at base-year values of energy use to measure the impact of changes in either
energy intensities or economy-wide activity and structure components on overall
energy use. With
E in this case representing energy use at the national level, the
decomposition equations take the form
