True, but higher demand for heating in winter is not specific to Germany. In the end, Germany will likely need to import energy anyway - just as it does today. But this means this question may not be the most relevant.

Huh? It highlights the relevance. It’s easy to handwave ‘imports’ away - but import from whom, and how do they make the energy?

One could import it as ammonia from locations that can produce a lot of it via solar.
