The "response" have issues from being done by neolierals. Nuclear (actual, so fission) is expensive and dangerous enough to be a government-only show, It's not something that can be offloaded to private hands. Because of that neoliberals hate it.
Modern p.v. and eolic means tons of small "products" to be sold and sold regularly because as long as tech improve after 10 years even if a plant is still fully functional it's about time to refresh it. As a result means a very profitable business for private companies (just try to track those behind Greta Thumberg, you'll end up quickly to giants like ABB, Ökoworld AG, Dii GmbH, Enel, EDF, Endesa, Abengoa, Siemens, Cevital and various investments banks). Oil giants are sitting on big money but they know their business sooner or later will end at least because of more and more scarce resources, so they like to diversify their investments. That's is. France have more nuclear because France have more public (have had, at least, with recent government and projects things goes very badly here)...
"New" nuclear projects are stuck for similar reasons: investors want profit, the service is just a mean to elicit profits, not a purpose and the profit a reward.
Swiss is luck to a certain extent because of it's small size and a certain policy toward autonomy, they aren't really autonomous especially recently but at least hydro thanks to the orography can play an important role and probably can still grow a bit toward many smaller-size plants so just pushing nuclear a bit they can be almost autonomous again. France to be autonomous must re-nationalize EDF erasing Hercules project and other disastrous neoliberal moves. Others are almost doomed: Germany have not good enough infra in the whole country, it's private-based development under USA control have had so negative effects that I do not know how they can be back in power, Italy is also doomed, Spain might have a bit more chances but I'm not much sure and other countries are completely out of the game.
Having a small p.v. with lithium storage I've reasoned a bit just in terms of personal energy autonomy in Green New Deal terms: having built s new house (Minergie-alike (BBC) if you are Swiss) I already have all electrical and winter heating demand far less energy than an old house, winter cooling is needed thanks to the climate only during the sunny days where there is plenty of electricity however try to be almost autonomous (witch means near-zero consumption from the grid, but with the grid as a cheap backup, cheaper than running on a generator) would mean are 30-40k euros more in both battery, a geothermic heat-pump since the actual heating (hot water stored in the garage + VMC + low inertia heat transfer to the house) stress batteries too much in many winter nights. Enlarging that to all houses: we can build something similar for individual homes in perhaps 50+ years. We still have to power industries. Even if in a soon future we can use e.v. as part of the house power plant (both to recharge them when not used, thanks to more than one car and WFH, and when they supply energy to the home microgrid) we are still not autonomous in a safe manner, the investment is a significant fraction of the entire home value and the worst part: it does not last longer. Batteries really used can last from 5 to 8 years while formally they'll last 10. That's means around 10-12k euros per year, doable for middle-class that will be impoverished by such hi prices but not doable for most others, a vast majority of the citizens. And still nothing to produce enough of such gears for even just only the middle class. Nothing for the industry, hospitals, shipping, airplanes etc. Long story short the actual new deal is a way to elict money from all to enrich few, making all much more surveilled (IoT is mandatory in such systems, and done in connected and proprietary ways) and poor. Witch is actually the 2030 Davos agenda. It's almost NOTHING for climate change (the sole part is that the need of new home might means homes able to offer better climate comfort, hopefully built in hydrogeologically safe places). Oil&gas will remain probably as long as we have them in sufficient quantities and nuclear will be kept going hoping for fusion, but all in a world ruled by private bodies so a world that can't really innovate.
