On: Solar and batteries can power the world

[uecker]

Germany has more wind in winter, so traditionally has more production of renewables in winter months.

[lazide → uecker]

It has dramatically higher thermal heat demands in winter - far higher than is compensated for by that. Even if everyone switched to heat pumps.

[uecker → lazide]

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.

[lazide → uecker]

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

[uecker → lazide]

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