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
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
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
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?
Summaries and Discussion Groups
Available on the Internet
The Energy End Use and Integrated
Statistics Division (EEUISD) within the Office of Energy Markets and End Use in the Energy
Information Administration has placed their Home Page on the Internet.
EEUISD, in addition to their
consumption survey data and publications, has placed the following sites related to the
measurement of ENERGY EFFICIENCY:
Efficiency in the United States Economy: A Beginning
Summaries have been posted for your review. The summaries cover the residential,
commercial, industrial, transportation sectors, and the economy.
Discussion Groups: Two
discussion groups have been started, technical and nontechnical. The first posting
includes statements from the 5 workshops. Future postings will be strictly based upon
comments that are received from visitors to our site.
