In the industrial and commercial sectors and in transportation other than automobiles energy intensity is defined as the amount of energy per unit of production. In the residential sector it is energy use per household and for automobiles it is energy use per car. A measure of the efficiency with which energy is used in the economy as a whole is total end use energy per unit of GNP.
The ratio of consumption to unit of measurement (floorspace, number of workers, etc.) Energy intensity is usually given on an aggregate basis, as the ratio of the total consumption for a set of buildings to the total floorspace in those buildings. Conditional energy intensity and gross energy intensity are presented. The energy intensity can also be computed for individual buildings. (See Conditional Energy Intensity and Gross Energy Intensity.)
The amount of energy use per unit of activity. (Source: Natural Resources Canada, Office of Energy Efficiency, Energy Use Glossary)
This is a unit of energy consumption per unit of [something]. In Energy For Planet Earth, this is given as a unit of energy consumption per unit of income.
Energy consumption per unit of output.
ratio between the consumption of energy to a given quantity; usually refers to the amount of primary or final energy consumed per unit of gross domestic or national product
Energy consumed per unit contribution to Gross Domestic Product, ie for business sectors it is the energy per unit Gross Value Added. The equivalent for the domestic sector is energy consumed per household.
The amount of energy used by an appliance or an industry to produce a product or service. For example, a fluorescent light requires only 20 watts to produce the same amount of light as a regular 100 watt light bulb, so its energy intensity is 5 times lower. Reducing energy intensity is one way to increase energy efficiency and emit less carbon dioxide.
Energy intensity is a measure of the energy efficiency of a nation's economy. It is calculated as units of energy per unit of GDP.
