The final energy consumption of the sector industry in 2017 amount 24 % of the final energy consumption in the 27 EU member countries, Norway, Switzerland, and United Kingdom. The consumption per energy carrier is splitted into following categories of application: Process applications (Process heating with different temperature thresholds), Cross applications (Information and communication technology (ICT), lighting and mechanical energies) and heating applications (space heating and hot water). Furthermore, the consumption is splitted into industrial branches.
The spatial distribution depends on the combination of the applications and the energy intensity of the industrial branch as following /FFE-52 19/: Process applications in energy intensive branches are distributed by the total emissions per branch, which is published by the European emission trading system (EU-ETS) /EC-02 08/ and the European pollutant transfer registry databases (E-PRTR) /EEA-01 07/. The emissions are combined with industrial sites. Cross Applications in non-intensive branches are distributed by employees per branch per NUTS-2-region /ECE-02 17/ and the population /EC-01 18/ per NUTS-3-region. Process applications in non-intensive industries are distributed on the basis of a share via emissions per branch and another part via employees per branch. Lastly, the heating applications are distributed by the heating structure and the employees per branch. Furthermore, a weighting of heating degree days has been considered for space heating like in the sector of private households and services.
The heating structure represents the share of each energy carrier used for heating within any NUTS-3-region. It is assumed that hot water is provided by the same energy source as space heating. The heating structure is based on a variety of national statistics, which are described in detail in the paper /FFE-103 19/. The result of the combination of the data of employees and the heating structure is a employees weighted heating structure (EWHS). The EWHS represents the share among all NUTS-3-regions. The sum of all shares of NUTS-3-regions equals one per energy carrier.
Furthermore, the space heating depends on the temperature. However, the data has to be processed further, due to the inertia of the building mass. The degree-day numbers (DDN) are computed as described in VDI 3807 with small adjustments and the daily equivalence temperature (DAT) is used for the base for the temperature inertia of the building. Adding up DDN of one-year results in the yearly degree-day number (YDDN), which is then calculated for each NUTS-3- regions and NUTS-0-level. Further important parameters, besides the indoor temperature, for the YDDN computation involve the indoor temperature and heating threshold temperature. These parameters are set to 20°C and 15°C according for all countries, as there is a lack of country specific data. Hence, the EWHS is weighted by the YDDN.
Finally the absolute amount of the final energy consumption in 2017 per energy carrier, application and industrial branches is available per NUTS-3-region. In the map the relative values per square kilometer of all energy carriers, applications and branches are presented and the absolute values by using the mouse over.
