Nuclear provided 50 years of low cost energy to France despite an uphill battle in the public opinion. Renewable energy is failing to save Germany this winter despite being hailed as the holy grail for the past few decades.
Everytime you listen to environmentalists talk you'd think we're already there, that countries are already covered with batteries for long term energy conservation, that a continental-wide energy grid has already been deployed (or will in the incoming week) so Finland can get electricity from solar pannels in Spain, that solar panels or wind turbines are great for our sovereignity when they're being produced in China, that they are infallible ecologically when they require rare materials and aren't systematically recycled.
No, green energy is not there yet, and it definitely won't before quite a bit of time. People failing to realize that and fighting teeth and nails against nuclear are gonna cause our demise if they keep at it.
