There is something to the principle that you should sweep your own door first. Let’s take the federal government, for example, which discussed the energy transition at various retreats in Meseberg Castle, which includes the ban on new oil and gas heating systems from 2024. And how is heating in Meseberg? Answer from a government spokesman: "The guest house of the federal government (...) is currently heated with natural gas. In coordination with the owner, we are examining the conversion of the heat supply to renewable energies wherever possible.”
If we subtract “check” and “if possible”, the answer is: We have a gas heater.
