This is all nonsense. For one, EV batteries are uniquely required to be as energy dense as possible, which is why they use LiPO batteries which are very expensive, dangerous to overcharge, and degrade when charged to high degrees. They are awesome for energy density, which matters when you have to haul that mass around all over the continental US over the course of a vehicles life.
Grid Storage is entirely different. Enter LiFePO4 batteries. These are best charged too 100% all the time. They also degrade far lower, and are the 1,000,000 mile batteries people talk about. They can be fully discharged and recharged up over and over again with negligible change in charge capacity. Fires for both types are very rare, in comparison to almost every other kind of power production, save maybe for solar fields, they almost never catch fire. If and when they do, it just becomes a matter of using the right extinguisher, which the world is getting better and better at understanding. You think Natural Gas plants never catch fire? Or methane power plants? Riiiiight.
All this is to say, this is good news. I just hope CA can keep up with renewable expansion at the rate needed to meet its goal of moving so aggressively for EVs. Grid use will undoubtably go up. But thats a good thing. Better to build a more robust grid and save the oil for shit we don't have alternatives for, like medicines, specialty plastics, hard to synthesize oils, and hydraulics.
