> The German government tried to force people to use more renewable energies and electric cars by introducing the CO2 tax.

Since both are not adequate replacements, costs for heating, electricity and transportation exploded.

This is total nonsense. The subsidy for fuel prices were introduced due to rapidly rising costs for fuel shortly before the war started.

Those costs didn't rise because of the CO2 tax.

The fuel subsidy also doesn't reduce energy taxes, but explicitly fossil fuel taxes for cars only.
