To clear up a few myths:
Topic e-car: With e-fuels, only 15% of the originally used energy remains. With e-cars, 70-80%. For towing, vintage cars, etc., they are certainly an option, but from an energy perspective not for the masses. The energy situation is similar for hydrogen as a gas replacement compared to a heat pump. And e-cars are also usable in rural areas except for a few justified exceptions. Fortunately, nothing is forbidden, this will anyway be regulated by costs (currently 100 km with an e-car costs €5 and 100 km with a combustion engine €10).
Topic insulation (and its balance): Very little of the oil currently used is spent on insulation material manufacturing (<1%). Most is burned, whether in a car, house, or elsewhere. Insulation saves 80 times the oil required for its production over 50 years. The price aspect is a different matter, especially at the moment. But this will also level out until it makes financial "sense" to insulate.
Topic photovoltaics: In new construction, it is, in my opinion, almost ridiculous to get upset about a mandate. Calling the €10-15k “a deal breaker” on a project volume of over €350k does not correspond to the truth. In existing property purchases and projects from €150k-250k, the €15k is more significant, I understand the financial concerns there. But even there, installing photovoltaics pays off financially if the bank cooperates with the increased financing amount. And with every self-used kWh, it becomes more financially worthwhile. And that it pays off financially is always the best approach for change.
And feel free to continue the discussion, but please without Third Reich or old man comparisons.
