“Options include reserve thermal power plants, battery storage or cables for importing electricity from other markets.” Or nuclear. Sad that this isn’t seen as an option any longer.

Yup.. This HAS to be on the table if we want ANY hope of powering a society anywhere near 100% renewable!

Did you include solar energy, energy imports or demand shaping in your model?

Oops I forgot to put the link to my model. For your specific questions: - Solar energy: sort of, I did three variants (100% solar, 100% wind, an the current Wind/solar ration) - energy import: I kept the same energy import profile as of today. It would have made the model much bigger (I would have needed to simulate the entire European grid instead of just the French one, making me deal with tons of different data so…

>I did three variants (100% solar, 100% wind, an the current Wind/solar ration

The first two seem pointless and the third I dont really get (it'll be much higher for both).

>I kept the same energy import profile as of today.

Also a weird assumption. It should be much higher in the future. Grid interconnects are a whole lot cheaper than batteries.

Switzerland is likely to import more excess power when theres a lot of wind/sun, use less of its own hydropower and release that pent up hydropower back across the border later, for instance.

>demand shaping not at all, and it would definitely have an impact for short periods

This is probably where the biggest bang for the buck will come as the demand side reacts to electricity prices that vary a lot over the day with smarter consumption. It's already happening in the UK and Germany.

Maybe, maybe not. At least back then, the threat of violent revolution was real and actualized. I don't think any group of revolters could defeat any of the modern western armies.

You mean like the USA in Vietnam, the USSR in Afghanistan, or the USA in Afghanistan?

Were you dropped on your head as a baby?

Decisions like these seldomly are about engineering alone. France didn't embrace nuclear out of the goodness of their hearts - they wanted to become a nuclear power, and needed the infrastructure and specialists and so on to become one (establish study paths, and give those students the prospect of jobs so that they actually choose the new paths etc.). Now that this isn't of strategic importance anymore, France lost…

Japan is also loser for WW2 but their lab/company do nuclear development from 1950s, thanks to relationship to US.

Yes, because in the case of Japan, the US heavily lobbied for them to develop nuclear power: https://en.wikipedia.org/wiki/Nuclear_power_in_Japan#Early_y...
