The process shows: The generational task of energy transition, which affects all sectors and branches of the economy, but also every individual citizen, must be solidly financed and must not stand on shaky ground. Planning and legal certainty are a very valuable asset, especially in the world of business. This applies even more to long-term industries such as the real estate industry. We don't just think until the next annual financial statements or the end of the legislative period, but often over decades. Therefore: Sleight of hand à la “left pocket, right pocket” should not be the basis for financing and promoting important energy transition projects.
