Lets round up its generate to 4gw Solar last year: 228gw was ADDED globally. SO about 57 plants of the size of the one near your house every year. 400 nuclear plants will give us about 2 major accidents every 50 years at current rate. We can assume this is pretty close to a constant as plants age, natural disasters happen and everything gets more complicated. Meanwhile solar is not responsive and doesn't work after dar, so needs storage. In a pure nuclear set up, you still need storage, because it isnt responsive (you can't just crank them up and down like a dimmer) ... Nuclear, all nuclear, has the down side of needing local power. If you have to shut down in an emergency you need to keep shit running (this is what killed Fukushima in part)... so we either need on site generation or a more complex grid, and probably because of safety, both. It's not a question of IF we have an accident but when, and more plants doesn't make them safer it just lowers the time between accidents... We aren't building more nuclear for a good reason. I does not make ANY sense to do so, the cost and complexity is too high for too little power.

With the disclaimer that I'm pro solar your accident based argument is weak as it ignores all accidents in resource mining for renewable infrastructure .. which will only increase as to date renewables make up only a fraction of the energy still generated by coal which is due to be replaced. Make no mistake, accidents (death and injury) in resource mining (non nuclear) greatly outweigh the total deaths and injuries due to just uranium mining | processing and nuclear power accidents. Lithium for batteries has barely started compared to where it is headed and we already see waste storage issues (Lynas, Malaysia) for large volumes of acids and associated low level radioactive waste. Again, I'm pro renewables, but as an exploration geophysict who has worked on global mining databases I can state as fact that these (as do all things) come at a cost - and accident free is not a reality. You're making a purely emotive argument based on feels sans actual real world data.

  not who you responded to but... Do we even have enough lithium etc. to produce all the solar panels (and batteries for ev's ??) we're gonna need ? P.S. - good point on the dangers of mining!

    It's highly probable we will have enough economically viable lithium from ground mining, we have "known measured reserves" that are less than we need (but have been explored, drilled, and modelled) and an excess of indicated resources (which are places trace tested that look a lot like other places with good reserves, but have not yet been drilled). Then there's seawater (which always gets bought up but isn't really a thing yet). More to the bigger picture, it's not just lithium - Vanadium redox batteries are better for grid storage where light nimble weight for a mobile vehicle doesn't matter so much. https://en.wikipedia.org/wiki/Vanadium_redox_battery https://en.wikipedia.org/wiki/Vanadium_redox_battery Not to mention other ongoing battery research and forms of energy storage (thermal mass, hydrogen, ammonia, etc) that make sense in an abundance of renewable energy that may soon arrive.

      oh - the Vanadium thing is interesting... I guess the poor round trip efficiency and poor energy-to-volume ratio are what we're waiting for before they become more common? speaking of ammonia - what do you think of ammonia engines? I just recently heard of them...

    The battery and the panels we can do. ITs the upgrades to the grid that we aren't close on and aren't making progress on. If you have an all electric house, a 3 day battery, all electric appliances and cars to charge... works great. Now how about a week of rain. Suddenly your either powerless or your utility has to import enough power to keep that all electric everything running. It's more lines, and transformers. We can't maintain global transformer demand today. A large disaster would be crippling (think solar flair, terrorism). It has been a major issue for Ukraine to replace this damaged infrastructure (due to production constraints).
