Expansion of wind turbines in Germany could achieve the goals of the current federal government by 2030. The Handelsblatt reports on an evaluation of the Institute of Energy Economics at the University of Cologne (EWI).
“According to EWI, 5.8 wind turbines with an average output of 4.2 megawatts each would have to be added daily from 2023 to the end of 2029. Possible dismantling of old plants is included. The historical comparison shows how enormous the task is: On average between 2010 and 2021, around 3.5 wind turbines were erected per day, with an average nominal output of only 2.8 megawatts.”
The plans for heat pumps are just as ambitious. The Tagesschau reports:
“Heat pumps are particularly on the agenda. They are regarded as saviours in the energy transition and heating technology of the future. This is because they are electrically operated and can thus use the clean electricity from wind turbines and solar systems. In addition, there is a high degree of efficiency compared to other heating options. The Federal Government therefore has the goal of integrating the heat pump as the new number one heating system in Germany. According to the plans, 500,000 heat pumps are to be installed annually from 2024. By 2030, there should be a total of six million devices in Germany.
However, from the point of view of the German Heat Pump Association, a shortage of materials and bottlenecks among craftsmen could slow down the ramp-up. The waiting times are already between half a year and one year. “We come from a production capacity that was previously designed for a market of 150,000. But the demand is already running out to 500,000,” said the head of politics of the association, Björn Schreinermacher. However, the industry has made it clear that rapid expansion is possible.”
