There are far too few skilled workers to implement the conversion plans, said Landsberg. In addition, the necessary infrastructure such as efficient power distribution networks is missing.

The Association of Municipal Companies (VKU) also described Habeck's plans as "not feasible". The planned rules for new heating systems "are completely inconsistent with reality," said managing director Ingbert Liebing of the newspaper. At the time of the planned ban on oil and gas heating, "there will not be enough green hydrogen or biomethane available anywhere in Germany" "and will reach the end customer via the gas distribution network".

The Vice President of the Central Association of German Crafts, Franz Xaver Peteranderl, in turn described the ban plans as "economic nonsense". These are "neither personally nor technically feasible in the short time and also not to be financed".

The installation of new gas and oil heating systems is to be banned from next year. A draft of the Ministry of Economic Affairs and the Ministry of Construction, which became known on Tuesday, states: "From 2024, only new heating systems should be installed in buildings that generate at least 65 percent of the heat provided from renewable energies." According to expert estimates, only the installation of district heating systems, heat pumps and biomass boilers is possible with this limit value.
