This is where I'm hoping the combo of electric cars and solar will pay off. The car can provide a local buffer when the family is at home during the night, but isn't needed when the sun is shining. I think the missing piece of this puzzle can hopefully be filled by something like Ambri's (previously LMBC) liquid metal battery tech [1]. A shipping container or two per suburban block, or urban building should be able to provide enough buffer, and then the load is sort-of evenly distributed, and hopefully makes the power management of the grid a little bit simpler as a side effect.
