Concept
Energiewende
Résumé
The Energiewende (ʔɛnɐˈɡiːˌvɛndə) is the ongoing transition by Germany to a low carbon, environmentally sound, reliable, and affordable energy supply. The new system intends to rely heavily on renewable energy (particularly wind, photovoltaics, and hydroelectricity), energy efficiency, and energy demand management.
The last nuclear power plants were shut down in 2023; all existing coal-fired generation will be retired by 2038. Legislative support for the Energiewende was passed in late 2010 and included greenhouse gas (GHG) reductions of 80–95% by 2050 (relative to 1990) and a renewable energy target of 60% by 2050.
Germany had already made significant progress on its GHG emissions reduction target before the introduction of the program, achieving a 27% decrease between 1990 and 2014. However, the country would need to maintain an average GHG emissions abatement rate of 3.5% per year to reach its Energiewende goal, equal to the maximum historical value thus far.
A controversial part of the program was the phasing out of Germany's nuclear reactors, supposed to be complete by 2022 but postponed to 2023, to reach a 100% renewable energy system. This process is mostly complete, with three reactors remaining connected to the grid (as of March 2023). Germany's overall energy mix still has a high intensity due to large share of coal and fossil gas.
The term Energiewende is regularly used in English language publications without being translated (a loanword).
The term Energiewende was first contained in the title of a 1980 publication by the German Öko-Institut, calling for the complete abandonment of nuclear and petroleum energy.
The most groundbreaking claim was that economic growth was possible without increased energy consumption. On 16 February 1980, the German Federal Ministry of the Environment also hosted a symposium in Berlin, called Energiewende – Atomausstieg und Klimaschutz (Energy Transition: Nuclear Phase-Out and Climate Protection).
