Data centers are absolutely consuming a bunch of power and we're paying for it, I agree!! California suffered brown outs from everyone charging during there day at work or at night. Idk of that's been corrected, but that's also why Trump relaxed coal and oil regulations so we could get enough power-though I hear some data centers are using jet engine turbines to supplement them smh.
So while batteries can be affordable, lithium is too dangerous, and the technology hasn't quite got to the point for widespread adoption, my opinion. Solid state and sodium ion are better technologies just around the corner that offer loner range, faster charging, and safer in accidents.
