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

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 2017. The indicator decreases with fluctuation. No differentiation is shown between the individual uses.

Final energy consumption associated with buildings decreased by 6.9 % between 2008 and 2017.However, according to the 2010 Energy Concept, the indicator should be decreasing by 20 % between 2008 and 2020.This target is to be achieved with the help of the National Energy Efficiency Action Plan and the Energy Efficiency Strategy for Buildings. read more

Indicator: Energy productivity

A graph shows final energy productivity from 1990 to 2017. It has been rising by 49 percent since 1990. Final energy consumption and gross domestic product are also shown.

Energy efficiency can be measured using the indicator ‘final energy productivity’.Between 1990 and 2017, final energy productivity increased by approximately 49 %.The Federal Government plans to increase final energy productivity by 2.1 % every year.Between 2008 and 2017, the annual average growth has been 1.15 %, which is significantly below the target. read more
