Focus Questions

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?

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:

Publication: Energy Efficiency in the United States’ Economy: A Beginning

Workshop Summaries: 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.
