Once you have batteries you may do so with solar or wind

  Yeah, but sometimes the intermittency is pretty extreme, and you can get away with significantly less overpaneling and storage if you have a mix of power sources. Not many experts advocate for 100% renewables.

    Right; batteries aren't really suitable for the low frequency part of the supply/demand mismatch. Daily storage, great, perhaps up to 1 week, but lower frequencies they are increasingly expensive. But there are other storage ideas that do much better for that. For example, burning an e-fuel like hydrogen, or ultra low capex thermal storage.
