I mean, that points to a Joule article that says: “If other sources meet demand 5% of the time, electricity costs fall and the energy capacity cost target rises to $150/kWh.” (Ie from $20/kWh). In other words, the grid can easily go to 95% variable renewable using storage costs the same as what they are right now. I should point out even nuclear power tends to use fossil power for backup, and synthesizing hydrogen for industrial uses could also be used to provide that last 5% affordably. That’s why when you add hydrogen season storage (to lithium daily storage), renewables are very competitive with nuclear even at 100% bAsElOaD. See: https://model.energy https://model.energy for an illustration of this. But seriously, getting to even just 95% clean energy would be a massive win, and the most important thing is getting to 95% clean within 20 years, not 100% in 40. (Or actually, getting to 80% in 10 is even more important, and to do it in a way that doesn’t massively increase energy costs, because we also have to eliminate natural gas for heating and petroleum for transportation.) (And I’m a big proponent of nuclear, but you can just build renewable WAAAAY faster in 2023. And that’s what matters… well that and not prematurely decommissioning existing nuclear!)
