Energy Efficiency

On the European as well as the national level, decisions in terms of energy policy have taken effect over the last decade. In accordance with the current Guideline for Energy Efficiency 2012/27/ EU, the primary energy consumption should be reduced by 20 % in all states of the EU until 2020 [1, 2]. Due to these changes, an energy concept has been set in Germany. Until 2050, green house gas emissions are to be cut down by 80 % compared to 1990 and the primary energy consumption should be halved in regard to 2008 [3].

End Energy Consumption by Sectors

Figure 1: End Energy Consumption in 2016 by sectors [4]

A third of the end energy consumption is caused by the manufacturing industry, presenting a significant energy-saving potential (see fig. 1). According to the dena (German Energy Agency), companies can usually reduce their energy consumption by 30 % with typical energy efficiency measures [6].

The exploitation of energy-saving potentials makes a considerable reduction in energy costs concurrently possible. The energy costs (see fig. 2) for companies increased by 30 % from 2006 to 2016. Due to the increasingly scarcity of resources and the energy turnaround, a further rise in energy prices is to be expected.

  • EU climate target: reduction of green house gases by 80 % compared to 1990 until 2050
  • The industry as a sector with a significant end energy demand provides a great potential to contribute to the climate targets.
  • Rising energy prices are a critical competitive factor for the industry.
  • The potentials for energy savings in the industry are tremendous and many measures often economically advantageous.
  • Our vision of the production of the future: energy-transparent and energy-optimized! Our activities in research, transfer and education strive for that.
