Figure 1. Energy-Intensity Indicators for the Manufacturing Sector
a. Change in Energy-Intensity Indicators, 1985 to 1988
b. Change in Energy-Intensity Indicators, 1988 to 1991
Note: The ratio of the
energy-intensity indicator represents changes in thousand Btu per 1987 dollars.

1. There are two types of energy-efficiency indicators: a. Aggregate indicators which use data that are frequently available and are easier to construct. b. Comprehensive more detailed indicators where the data are not as frequently available and the indicators are more complex to construct. c. Considering the trade-offs, which type of indicators should EIA present and why? 2. Should EIA aggregate the sectoral coverage or leave the coverage disaggregated; that is, should there be: a. Buildings sector indicators versus separate residential and commercial sector indicators b. Transportation sector indicators versus passenger and freight indicators c. Industrial sector indicators versus separate indicators for manufacturing, agriculture, mining, and construction? 3. Should EIA deal with the energy losses incurred in the generation, transformation, transmission, and distribution stages at the entire economy level, sectoral level, or both levels? How should EIA deal with these losses? Should only the losses in the electricity generation sector be considered or should the losses be considered in the other energy sectors as well? 4. For each sector, should EIA have a single indicator or multiple indicators to illustrate the variability of efficiency trends, depending on the approach used? 5. In your estimation, which of the energy-intensity indicators presented in this report are the most robust, valid, and reproducible? Please explain. 6. Do you use any other potential energy-intensity indicators that are robust, valid, and reproducible? 7. With what frequency should EIA publish the chosen indicators of energy efficiency? |
