Decomposition tool

The objective of this tool is to explain the variation in energy consumption over a given period through a decomposition into different explanatory effects, the most important of which are economic activity and energy savings. Other effects depend on the sector (e.g. lifestyles changes, structural changes).

The user first has to select the country and sector for which consumption is to be decomposed:

• Primary, i.e. total energy supply. An option is available to display primary energy consumption (definition of Article 4 of the EED 2023 used for the EU targets).
• Final, i.e. total final energy consumption (without non-energy uses)
• Power
• Industry
• Transport
• Households
• Services
• Agriculture

For some sectors, a sub-sector can be selected (e.g. space heating for households, cars for transport).

Several options are available:

• Change the period of decomposition
• Change the unit in which the variation in energy consumption is measured
• Change the type of graph used to display the decomposition (waterfall or histogram)
• Make the decomposition at normal climate
• Make the decomposition using technical or gross energy savings. Technical savings correspond to gross savings corrected for negative efficiency trends due to the inefficient operation of facilities in industry (e.g. kilns, boilers, motors) or behaviours (e.g. higher heating temperature).
