Indicator: Energy consumption for buildings

A graph shows the building-related final energy consumption for room heating, room cooling, hot water and lighting for 2008 to 2022. The indicator decreases with fluctuation. No differentiation is shown between the individual uses.

Final energy consumption associated with buildings decreased by 15.2 % between 2008 and 2022.However, according to the 2010 Energy Concept, the heat demand of buildings should have decreased by 20 % between 2008 and 2020. In fact, consumption fell by only 10.9 %.Due to the Russian war of aggression against Ukraine and the subsequent efforts to save energy in Germany, final energy consumption in bu... read more

Indicator: Final energy productivity

A graph shows final energy productivity from 2008 to 2022. Productivity rose by more than 26 percent since 2008. Final energy consumption and gross domestic product are also shown.

The efficiency with which an economy uses energy can be measured by the "final energy productivity" indicator.Between 2008 and 2022, final energy productivity increased by 26%.Reducing energy consumption is more important than increasing energy productivity.The European "Energy Efficiency Directive" and the German "Energy Efficiency Act" set ambitious targets for reducing final energy consumption. read more

Rebound effects

Efficiency increase oftentimes reduces product or service costs, which can in turn ramp up consumption (due to reduced prices), thus partly canceling out the original savings. This is known as the rebound effect. read more
