Energy Intensity Indicators
Highlights of Trends
Energy intensity trends are reported in two categories, total energy and delivered energy, for each of the four end-use sectors (transportation, industrial, residential buildings, and commercial buildings). Select the images below to learn more about these energy intensity trends:
Energy efficiency is a vital part of the nation's energy strategy and has been since the first oil crisis in 1973. As part of a national priority for improving energy efficiency, the Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy (EERE) established a new national system of indicators to track changes in the energy intensity of our economy and economic sectors over time.
This system of energy intensity indicators can:
- show us how the intensity of energy use and its components are changing
- help raise public awareness about how and why energy intensity has changed over the years
- compliment other provided inputs to policy and program analyses, including improved understanding of the impact of program and policy choices on energy intensity, such as supplementing energy demand forecasting or assessments of a program's influence on energy intensity changes
- improve understanding of the role of efficiency improvements in our changing energy markets
The purpose of this site is to provide the public with information on energy intensity indicators that can be used to consistently track changes in U.S. energy intensity over time.
This new system of energy intensity indicators provides:
- Indices of energy intensity trends from 1985 to 2004 that correspond to changes in the efficiency of energy use, to the closest extent possible
- Energy intensity, total energy use, and activity measures at the economy-wide level, sector level (transportation, industrial, residential buildings, and commercial buildings), and at even more disaggregated levels, where data permit
- Delivered energy use, energy intensity, and activity measures at the economy-wide level and for five sectors (the four end-use sectors and electricity generation)
