The IPCC 1.5°C report published late in 2018 presents 89 mitigation scenarios in which nuclear generation grows on average 2.5 times from today’s level by 2050.
Besides the fact that no one predicts how much more renewables can scale, where prices will go, and whether they will be enough. All it takes is one war or a few more tariffs with China to screw up renewable-only decarbonization.
That's why it's important to diversify and not assume anything. If a source is green, it must be used.
Then it's curious how all the anti-nuclear people I argue with are from Germany. You have chosen your own path, don't come and impose your ideologies on others :)
