Energy Intensity Indicators in the U.S.: Economy-wide (1949 - 2004)

Energy intensity data and documentation published by the U.S. DOE's office of Energy Efficiency and Renewable Energy (EERE). Energy intensity is defined as: amount of energy used in producing a given level of output or activity; expressed as energy per unit of output. Economy-wide energy intensity is also referred to as aggregate energy intensity. This is the energy intensity of the entire U.S. economy, and aggregates the intensity of the four major energy consuming end-use sectors (transportation, industrial, residential buildings and commercial buildings) and the electricity producing sector. Data is available for the period 1949 - 2004.
