Useful Energy Intensity

The useful energy intensityThe average energy consumption of some device or end-use per unit of activity. screen only appears when conducting a useful energy analysis and is only defined at Category with Energy Intensity branch types () .

Unlike a final energy intensity, which specifies the amount of fuelSomething combusted, or otherwise used to produce energy used per unit of activity, a useful energy intensity is a measure of the energy service provided per unit of activity -- the "useful" energy. Examples include the heating load of a building (NOT the fuel used in its boilers) or the amount of heat in a cooking pot required to cook a meal (NOT the amount of wood burnt).

Useful energy intensities are calculated for Current AccountsThe starting data for all scenarios. The Current Accounts can include data for just a single Base Year, or data for multiple historical years between the Base Year and one year before the First Scenario Year. based on the fuel shares and efficiencies of devices. This calculated value is displayed for you to project into the future when editing scenarios.

Refer to Useful Energy Demand Analysis for information on how to configure branches for entering useful energy intensities.

Note: Because they are not associated with a particular fuel, LEAP only lets you enter useful energy intensities in energy units.
