alt Hacker News> Is a purely wind/solar + battery grid viable?
Yes.
(I don't disagree that a diverse mix is good, and I'm all for nuclear, I'm just saying the old "it's intermittent and can't grid form" boogeyman is no longer true. It would also really behoove Western countries to start manufacturing batteries at scale if we don't want to get a bloody nose in the future, because they're good for more than just the grid)
If it was viable it would have happened already. We have a massive oversupply of solar and wind, particularly on the west coast. Generation is the easy part.
We have terrible storage and transmission, the parts that are actually expensive.
