That's fairly of high level of smug certainty in the headline considering that many US gen 3 nuclear plants that did start are unfinished and struggling to contain their overruns to 2-3x their initial budget. Even China which arguably did make the that big bet is cutting back on the number of nuclear plant projects in their large push (though we are seeing the first few plants of their big investment wave come online today - perhaps we will seem them resume, but I wonder about their safety practices in that wave). But the pullback in China suggests some of their internal data said to them that there was reason to pull back the goalposts a bit.
Nuclear power isn't carbon neutral, and it's hard to describe how it can be possibly be described as "clean".
An honest discussion of lifecycle emissions of nuclear power vs renewable energy would be good to see, but this isn't it.
aren't Fukushima & Chernobyl good examples of why not to go nuclear?
