Even if you can somehow shorten the planning processes: We are in the middle of a workers shortage and a supply-chain crisis. Who should build all these wind parks? And all the other things you listed, like building isolations and heat pumps. Shut down universities and require everybody to work in construction for a couple of years? > we need to conserve as much energy as we can in the meantime. Why? What's the outcome? Kill the economy? Who should pay for all these things? > Biogas has a lot of potential, as well as geothermal. Biogas needs agricultural land and thereby competes with food, and thus has other implications. Geothermal would be nice to have, and I think everybody agrees on that, but it's going nowhere. And as far I know not only in Germany, but everywhere.
