> Germany could replace gas boilers with heat pumps Given that burning gas in modern electricity gas plants (like Germany has) to power modern decent quality heat pumps is more efficient (and flexible, and future proof) then burning Gas for heating that would be the best solution. It's also completely unrealistic. Given how common gas powered house central heating is, and given that some houses have worse constructs (like gas heater per apartment for warm water) I would guess that we would need 1 heat pump per 100 people or more. That would be 800_000 modern decent quality heat pumps. Which all need to be produced, build, shipped and installed. We already have a shortage of craftsman in Germany, even if we ignore everything up to installation that would be a major problem. And that's under the assumption that houses can be retrofitted to use heat pumps. But for many houses, especially apartment blogs this would be a problem as there is no good way available to montage/connect the outside-of-house parts of a heat pump on many typical German apartment blogs (living in apartment in apartment blogs is normal in Germany). (You still can do it, but even more cost and time involved). There are other problems, too. So I guess the optimal solutions is practically not possible.
