Cooling energy demand: significant savings in Germany

In Germany, the large increase in the number of refrigeration equipment has little impact on energy demand.

A study entitled Energiebedarf für Kältetechnik in Deutschland*, presents the evolution of refrigeration technologies in Germany. Eleven fields of application are studied, including among others: domestic, commercial and industrial refrigeration, air conditioning and heat pumps.

The document, published by the professional association VDMA, is an update of a first study published in 2011. A comparison is made between 2009 and 2017.

In 2017, there were 144 million refrigeration systems in Germany, an increase of 16% over 2009 figures.

In contrast, energy consumption only increased by around 6%, from 82 TWh to 87 TWh over the same period.

In 2017, 84% of energy needs related to refrigeration in Germany were covered by electricity (i.e. 14% of the country's electricity consumption).

Together, including non-electric systems, refrigeration accounted for 5.6% of Germany’s primary energy demand in 2017.
