I like Vaclav Smil’s shorthand tool for assessing these claims. Be suspicious of any predicted year for full renewable rollout that ends in a zero or a five.
This is silly: the estimates are rounded, because there's huge uncertainty. It's a very long way away from "these plants will come online on these dates". Perhaps "2045 plus or minus five years"?
We all understand how difficult software development time estimation is, right?
From Smil this is a valid criticism in my opinion. He's got the data and he knows how to do the math, so he's basically saying come correct if you want to debate at his level.
