Energy efficiency is a key tool to reduce greenhouse gas emissions. Every kilowatt-hour that is not consumed does not have to be generated in the first place. In the 29 member states of the International Energy Agency (IEA), energy efficiency improved by 14 percent between 2000 and 2015.
Final energy productivity is used in Germany as one of several sustainability indicators. In the period from 2008 through 2050, the objective is to increase final energy productivity by 2.1 percent a year. To further improve energy efficiency, a strong focus will be placed on the four areas of action that together make up the lead market for energy efficiency. The structure of the market segments in this lead market reflects those consumer groups that harbor the greatest potential for energy savings: industry, commerce, the service sector and the real estate industry.

The structure of the market segments in this lead market reflects those consumer groups that harbor the greatest potential for energy savings: industry, commerce, the service sector and the real estate industry. The market segment for energy-efficient production processes concentrates on the core processes in a variety of industries. With this central focus, it offers companies ways to optimize their processes and thereby reduce their energy consumption. The technology lines in this segment cover important industries such as basic chemicals, retail and logistics, automotive engineering, food production, the metal production industry, metalworking, and paper and cardboard manufacturing.
Saving energy in the building sector is another essential element in efforts to reduce both energy consumption and greenhouse gas emissions. Energy-efficient buildings constitute a separate market segment comprising four main technology lines: efficient heating, ventilation and air-conditioning (HVAC) systems, building automation, thermal insulation, and passive houses/PlusEnergy houses.
An additional market segment covers energy-efficient appliances. The focus here is on ways in which companies and private consumers can save energy in the operation of electrical appliances. The latter break down into white goods, consumer electronics, lighting, and information and communication technology (green IT).
The market segment for cross-sector components groups together technology lines that help companies in any industry to save energy in what can be referred to as auxiliary production processes. Electric drive systems, compressors, compressed air and vacuum technology, pump systems, process control instrumentation, ventilators, heat exchangers and measurement and control instrumentation all belong to this segment.
