> in particular solar doesn't work in emergency situations such as volcano eruptions rendering the sky dark. I'm not familiar with this. Is this a common problem in Germany? Are southern states like Baden-Württemberg more afflicted or less compared to more northern ones like Schleswig-Holstein?

No, but winter is. Inclination of the earth means solar produces considerably less energy in winter and this is even more prevalent in far northern/southern latitudes. Also cloud coverage can drastically reduce solar output.

  We really need to locate the panels near the equator, and combine it with one day of storage. There is a project like this: https://electrek.co/2021/09/27/the-worlds-longest-subsea-cable-will-send-clean-energy-from-morocco-to-the-uk/ https://electrek.co/2021/09/27/the-worlds-longest-subsea-cab... The problem for doing this large scale if the right of way for the HVDC lines. I'm watching this on a smaller scale in Massachusetts, where Maine voters are blocking a HVDC link to Hydro Quebec. But I think this is a game between established interests.. in this case NextEra funded the ballot question and advertising, I think because they lost out on their SeaLink project (HVDC to Seabrook nuclear power plant). https://www.energy.gov/sites/prod/files/2020/09/f79/EXHIBIT%20O%20-%20PUBLIC%20OUTREACH%20MATERIALS%20%28W6270305x7AC2E%29.pdf https://www.energy.gov/sites/prod/files/2020/09/f79/EXHIBIT%... https://www.newscentermaine.com/article/news/politics/referendum-question-1-is-the-most-expensive-ballot-question-in-state-history/97-c7ee5cee-aa5b-4a2e-aa85-b66e092756fe https://www.newscentermaine.com/article/news/politics/refere...

No, it is a hypothesis of mine, that a large volcano eruption may disrupt the function of solar within a large area that was affected and which depends on solar energy. A particular example may be https://en.wikipedia.org/wiki/1815_eruption_of_Mount_Tambora https://en.wikipedia.org/wiki/1815_eruption_of_Mount_Tambora https://en.wikipedia.org/wiki/Year_Without_a_Summer https://en.wikipedia.org/wiki/Year_Without_a_Summer A single "year without summer" may be the fatal blow to a society basing their energy on solar energy, so I hypothesize.

  I don't think nuclear is much more resistant against forces of nature than solar/wind are... An INES level 7 accident in France could cause a similar outage in France's nuclear capacity (similar to Japan's nuclear lost decade). Or massive droughts could cause nationwide nuclear outages due to a lack of cooling water. Having a mix of nuclear/solar/wind with hydrogen as a "battery" in an EU super grid seems like a good way to mitigate the risks.
