If you wish to promote environmental protection, to foster a responsible way of dealing with our planet, you need to influence a variety of parameters. In commercial and industrial production, this involves, above all, the careful use of resources and energy. The good news is that while Germany’s economic output has grown over the last two decades, the country’s industrial energy consumption has decreased. One reason for this is the decline of industrial production in Eastern Germany, and generally lower energy consumption in the industrial sector.
The industrial sector no longer ranks first amongst the four major energy end-use sectors (the other three being transportation, residential and commercial), but has stepped down to second place. Most of the energy consumed in factories relates to process heat; it accounts for approximately two thirds of industrial energy consumption. A quarter is used up by mechanical energy. Heating buildings accounts for only a small fraction of overall energy consumption. In the industrial sector, energy conservation is not an end in itself but a way to cut costs and comply with legal requirements. Plus, as consumers are becoming more critical, it is becoming increasingly important for sales.
