Portugal powered their entire country on hydro power for a month recently.
Germany apparently did it last week or the week before on wind I think it was I read? Costa Rica also have the potential to use purley hydro power for 100% usage.
My issue with nuclear is the waste and dumping it. Digging a massive hole or dumping in a concrete block at the bottom of the ocean isn't an ideal solution. It's half life is what? 250,000 years IIRC? Like my old chemistry tutor used to say, we can't keep track of what happened 2000 years ago, what hope do you we have for quarter of a million years?
But that's my only beef with nuclear. Power wise its fantastic, employment wise it's awesome. For example I live about an hour away from somewhere called Trawsfynedd in Wales. That has a nuclear plant. It stopped operating in 1991 and became an educational facility of sorts for people to visit to learn about electricity in general and nuclear.
A few years ago it was decided to decommission it completely. The people who will complete the deconstruction of that plant haven't even been born yet. It's expected to be another 90 years. But that's 90 years of guaranteed, specialist jobs, just for deconstruction
