7.1.a, b Final energy productivity and primary energy consumption
When analysing energy consumption, a distinction is made between primary energy and final energy:
• Primary energy refers to the energy contained in natural energy resources such as natural gas, crude oil, coal or uranium prior to a transformation. Energy obtained from renewable sources also qualifies as primary energy.
• Final energy is the portion of primary energy that is made available to the final consumer in the form of, for example, electricity, district heating, gas, or fuels. It is derived from primary energy, minus the losses incurred during conversion, transmission, and storage.
7.1.a Final Energy Productivity
Final energy productivity describes the ratio between economic output – measured by gross domestic product (GDP) – and the amount of final energy consumed. It serves as an indicator of energy efficiency in the production of goods, the provision of services, and energy consumption in private households.
As the indicator is based on final energy, losses occurring during conversion, transmission and storage are not taken into account. Consequently, it does not provide information about the efficiency of energy transformation processes – such as the efficiency of power plants – or about advances in energy transmission and storage technologies.
Between 2008 and 2023, final energy productivity increased by 31.8 %, according to preliminary figures, with 10.8 percentage points of this growth occurring in 2022 and 2023 alone. Thus, the politically defined target of a continuous increase was achieved both in the most recent year and on a multi-year average.
Until 2019, the development of the indicator was primarily driven by an increase in GDP (+14.7 % compared to 2008), while final energy consumption remained relatively stable (–3.0 %). Between 2021 and 2023, GDP rose only slightly, while energy consumption declined significantly – from 94.2 % to 87.5 % of the 2008 level. As a result, final energy productivity continued to rise despite stagnating GDP.
Clear regional disparities are observable: in 2022, final energy productivity in Sachsen-Anhalt stood at €0.90 per kilowatt-hour – an increase of just 4.6 % compared to 2008. Sachsen-Anhalt thus recorded the lowest absolute value and the weakest growth in final energy productivity among the Bundesländer. The highest values were observed in the city-states of Berlin (€3.34 per kilowatt-hour) and Hamburg (€3.54 per kilowatt-hour). Berlin also recorded the largest increase among all Bundesländer, with a 72.8 % rise compared to 2008.
Total final energy consumption in 2023 amounted to 8,163 petajoules, down from 9,327 petajoules in 2008. Of this, approximately 14 % was attributable to the commerce, trade and services sector, 28 % each to households and industry, and 31 % to transport.
7.1.b Primary Energy Consumption
Primary energy consumption refers to the total energy content of all energy carriers used domestically. This includes primary energy carriers such as lignite and hard coal, mineral oil, natural gas, and energy from renewable sources. These are either used directly or converted into secondary energy carriers such as electricity, district heating, petrol or diesel.
The calculation is based on the sum of domestically produced energy carriers, plus the balance of imports and exports and changes in stock levels, minus the supply of fuels and lubricants to national and international maritime shipping in German ports. The basis for this is the energy balances of the Working Group on Energy Balances (Arbeitsgemeinschaft Energiebilanzen, AGEB), supplemented by additional data sources.
Unlike final energy productivity, this indicator does not incorporate any economic reference figures and focuses solely on consumption. Since it is based on primary energy, improvements in the efficiency of fossil fuel conversion – particularly in electricity generation – are taken into account. However, it is not possible to clearly determine whether changes in the indicator result from changes in energy consumption or from developments in energy generation, transformation and transmission. In the case of electricity generation from renewable sources, the energy produced is counted as primary energy, which means that efficiency gains in these systems are not directly reflected in the indicator.
Between 2008 and 2024, primary energy consumption declined to 73.3 % of the 2008 baseline, according to preliminary data. If the trend of recent years continues, the politically set target – a reduction in primary energy consumption of at least 39.3 % by 2030 compared to 2008 – is likely to be achieved ahead of schedule.
Here too, pronounced regional disparities are evident: while primary energy consumption in Sachsen rose to 102.8 % of the 2008 level in 2022, it fell to 73.5 % in Schleswig-Holstein and 66.5 % in Saarland.
