Energy Intensity

Jump to: navigation, search

Energy Intensity is a measure of the energy consumption per unit of gross domestic product (GDP) [1], [2], [3]. The Energy Information Administration (EIA) reports energy intensity in Btu per constant dollar value of the GDP [1].

In the United States, energy intensity has generally decreased each year since 1950 [4], as GDP continues to grow. In 2009, energy intensity dropped 2.4% from the previous year (average decline in energy intensity from 2000 to 2008 was 2.0%) [5].
