In 1980 the summer time was introduced in the course of the oil crisis. The aim was to save energy. But this is not really effective, my experts.
Study shows that year -round summer saves energy
Korbinian von Blanckenburg, Dean of the Department of Economics at the Technical University of the Ostwestfalen-Lippe Technical University, researches the subject of time change. In his study, the electricity consumption of private households was looked at and expected in a scenario with a year -round winter time and a year -round summer. It has been shown that the time change does not bring an advantage, he explains in an interview with ZDF. In fact, it has been shown that all year round would have savings potential, namely around 0.5 percent of the annual electricity consumption, at a price of 0.39 euros per kilowatt hour that would be 516 million euros a year.

The reason is that you would better use the evening brightness and the leisure activities are relocated a little more to the evening and that saves energy, according to Blanckenburg. The Federal Environment Agency also reports that the light is actually switched on in the evening due to the change of time in summer. Conversely, in spring and autumn, this leads to more heating in the morning. In fact, in the end you do not save any energy through the changeover. This also means Stefan Kapferer, chairman of the main management of the Federal Association of Energy and Water Management (BDEW), which already thinks in a press release from 2018: “In fact, the shoot on the pointer does not bring a noticeable energy saving. For years, the energy industry has not been able to recognize relevant effects on electricity consumption.” Rather, you have to modernize radiators, for example, because every third heating in Germany is 20 years old and older. In the case of electrical appliances, you should also include more power consumption in the purchase decision, these would be effective approaches to saving energy, according to the BDEW.
Why has the time change has not yet been abolished?
The EU Commission actually decided in 2018 to abolish the time change, but there are some hurdles when implementing. The basis for this decision was a survey in the EU with 4.6 million people who decided to overturn the time change. This seems to be many people, but it should be said that this is just one percent of the EU population and the majority of Germans were involved in this survey, according to the MDR. Among the Germans, the change of time is probably particularly unpopular, around 80 percent of Germans consider them senseless, reports the NDR. It is also reported that doctors estimate that it takes eight to 14 days for the body to get used to the changeover. The health effects on the biorhythm are comparable to a mini jet lag. On March 28, 2021, the proposal for an EU directive should have been turned over a last time, but so in April 2020 every member state should have decided which time standard would have been, this did not happen, especially as a result of the Corona crisis, the Timeanddate portal. The next step would be the decision of the European Council, but no decision has been made here either. It is not yet known when the time change will be abolished. Neither is it known whether there will be permanent summer time or normal time in the future.
