I think a good exercise for the reader is to reflect on why they were ever against nuclear power in the first place. Nuclear power was always the greenest, most climate friendly, safest, cheapest (save for what we do to ourselves), most energy dense, most long lasting, option.

So far it was either the cheapest or the safest.

Also, solar is now both cheaper and safer.

but it's not 24/7 and europe even worse in winter and fall. Solar is unrealistic to replace most energy usage [1]. In EU it's just less than 5% usage. In germany less than 6% usage. And wind is not a replacement either (less than 11% energy usage in germany).

And just for comparison in france nuclear power plants provides 37% of energy

60% of that energy is lost as waste heat and doesn't need replaced as we decarbonise and electrify.

For already developed nations predictions are for electricity to double but energy use to halve at the same time as they electrify end uses.

Not everybody live in house and have enough rooftop area. In Europe majority people live in apartments. If you want to have wind warm and solar farm there is also energy wasted with power lines transmission. Energy powerbanks also have energy waste.

I'm all in to have energy mix and more people to have solar panels if they can but it's not a holly grail

Take all the land area that we currently devote to oil extraction, refining, delivery, etc.

Just that tiny amount of land is enough to supply the entire world's energy needs, if covered with solar panels.

Power line transmission losses are negligible. We don't need to put solar directly at the site, just as we don't need to put nuclear directly at the site of energy use. The round trip efficiency of energy storage is accounted for in the cost of the storage, whether that storage is hydro, battery, or hydrogen.

Solar really is the holy grail of energy: super cheap, super scalable big, super scalable small, and highly distributable or centralized. Pair that with the incredible cheapness of current batteries, and their falling prices in future years, and we are looking at a future of incredible energy abundance. As long as we are willing to accept it.
