> 99% still means 3 full days of blackout every year. Or 3 days running otherwise-mothballed (and, yes, quite expensive per MW) gas plants or whatever to fill the gaps. There's a real problem in this discourse that wants to interpret things in absolutist ideas, when real solutions always end up looking a little patchwork in those last few percent. Reducing electrical grid carbon output by a factor of 100 (!!) is more than sufficient to meet anyone's climate goals. At that point, the low-hanging-fruit analysis will have long since moved on to transportation anyway.
