Energy intensity

Energy intensity is a measure of energy efficiency, which sets the energy consumption of an economy or industry in relation to earned gross domestic product or gross value added reached. It is defined as follows:

Depending on the problem and the emission of pollutants associated therewith can be included in the numerator instead of the initial amount of primary energy. In this case, the unit of energy intensity results in ( emitted quantity ) / ( unit of currency ).

The energy intensity does not necessarily refer to the economy as a whole but can also be calculated for a group of products or a single product.

A decline in energy intensity that is to be evaluated from the standpoint of sustainability is positive, can be achieved both by using modern (the energy efficient -use ) manufacturing processes as well as by the structural transformation of the economy, for example, away from the heavy industry to providing a service.

A decrease in the energy intensity results, however - mathematically - by inflation. A comparison of the energy intensity of the years the funds should therefore be adjusted for inflation.
