And long-distance transmission, storage, nuclear, geothermal... because we still want temperate buildings and movable vehicles when the weather is uncooperative

And long-distance transmission, storage, nuclear, geothermal... because we still want temperate buildings and movable vehicles when the weather is uncooperative.

Each EV has a battery that also acts as storage, so we have something at the start already.

  Do you really think people will voluntarily give away their miles during a shortage? Even after seeing the 2020 toilet paper scenario?

    Not unless they're properly compensated. However, it's already possible in some jurisdictions to play in the wholesale market with a home battery, and the same should apply for V2G. If they were offering, say, $2/kwh for the electricity in my car battery, unless I needed to take a long trip immediately afterwards I'd very happily take it. Wholesale peaks can go even higher than that on occasion!

      How many vehicle owners are flexible enough to give up driving for several days, in exchange for a $120 payout? I think EVs can smooth out the daily bumps, but we need something to stabilize the grid over longer periods without burning fossil fuels. At least for the US, lots of long-distance transmission should help, because weather events generally don't affect the entire country.

    If they are charging during low usage times, they are already doing that. In areas where that’s at night, EVs are in a good place grid-wise if they are charging at home.

      That's not really storage though; it's a day or two of load shedding. Unfavorable weather patterns can last for more than a week. Electricity prices are currently pretty stable from day to day because we burn gas or coal when all else fails.

        It is storage if you have a constant baseline like nuclear or coal that needs to be used in any case, and isn’t used as much at tonight. Yes, you could use pumped storage instead to capture unused baseline, but EV batteries charging at night work as well.

        Yes, nuclear is a good complement to ~24 hour storage, and removes the need for several-day storage. The problem with coal is that it's killing a lot of people.
