Indicator: Final energy productivity

A graph shows final energy productivity from 2008 to 2021. Productivity rose by more than 20 percent since 2008. Final energy consumption and gross domestic product are also shown.

Energy efficiency of an economy can be measured using the indicator ‘final energy productivity’.Between 2008 and 2021 final energy productivity increased by 20 %.The German Federal Government aims to increase final energy productivity by 2.1 % every year.Between 2008 and 2021 the annual average growth has been 1.4 %. This is significantly below the target. read more

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 2021. The indicator decreases with fluctuation. No differentiation is shown between the individual uses.

Final energy consumption associated with buildings decreased by 9,7 % between 2008 and 2021.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 12 %.Due to the cooler temperatures during the heating period, the final energy consumption relevant to the building has increased by 1,7 % compa... 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
