This would have been great 20 or 30 years ago but back then “nuclear bad!”. It would have been a great bridge between burning fossil fuels and wind/solar/etc. It probably would have prevented climate change from getting as bad as it is now. Oh well, here we are.
There’s a lag between human activity and climate change. Rolling out nuclear might have helped a bit, but whether we’d have seen the results today I’m not sure… the benefits would be in the future.
I doubt cars could have evolved any faster though (well they could, but capitalism, so realistically things went as fast as they could)… so it might not have had much impact at all.
It probably would have prevented climate change from getting as bad as it is now.
I just read the news yesterday that big coal, oil and gas want to step up their game, despite renewables being ridiculously cheap now. So i don’t think so.
