Indicator: Primary energy consumption

• Primary energy consumption (PEC) in Germany has fallen significantly since the end of the 2000s. It fell by about 27 % between 2008 and 2024.
• According to the Energy Efficiency Act of 2023, PEC is to be reduced by 39 % by 2030 compared to 2008. The ‘Greenhouse Gas Projections 2025’ by the German Environment Agency indicate that the measures taken so far will likely be insufficient to achieve this target
• The indicator PEC is methodologically distorted by renewables: If the share of renewables increases, primary energy consumption decreases, even if final energy consumption remains constant.

The use and generation of energy is associated with a wide range of environmental impacts: The extraction of raw materials such as coal or crude oil can cause significant damage to ecosystems. Energy is consumed during the transportation of raw materials, and greenhouse gases and harmful air pollutants are emitted. Environmental pollution also occurs during the conversion and provision of energy. Alongside the switch to alternative and renewable energies, reducing the PEV is therefore an important component of the energy transition.

However, the ‘primary energy consumption’ indicator is subject to a method-related bias: When the share of renewables increases, primary energy consumption decreases, even if final energy consumption remains constant (see section "How is the indicator calculated?" at the end of the article). The indicator ‘final energy consumption‘ is more informative with regard to the energy consumption of an economy.

In 2024, Germany consumed approximately 29 % less primary energy than in 1990. In 2006, consumption was still almost as high as in 1990. Since then, it has fallen significantly. In part, this is due to falling final energy consumption. Also, the switch to renewable energy sources and the increase in net electricity imports was accompanied by a disproportionate decrease in PEC as a result of statistical effects. Apart from that, the energy crisis 2022 led to significant energy-savings and for 2024 to the lowest energy consumption since 1990.

The Energy Efficiency Act (EnEfG) adopted in 2023 sets the target of reducing the PEV by 39 % below 2008 by 2030. The 'Greenhouse Gas Projections 2025' (in German only) examined whether Germany can achieve its energy and climate targets in 2030 on the basis of scenario analyses: If all the measures planned by the government are implemented, the PEC is expected to fall by around 32 % by 2030 compared to 2008 (‘with measures scenario’). This would clearly fall short of the EnEfG target of a 39 % reduction by 2030. Further measures to reduce the PEC are therefore necessary in order to achieve the EnEfG targets.

The total primary energy consumption is determined by the Working Group on Energy Balances (AGEB) on the basis of efficiency ratios. The energy carriers burnt in power stations and other combustion plants are multiplied by their calorific value. The efficiency ratio of electricity generated from wind, hydropower or photovoltaics is defined as 100 %, while for geothermal energy it is 10 % and for nuclear energy 33 %. Explanations of the calculation methods are published in the Preface to the Energy Balances (in German only).
