Re: Not enough batteries for recycle to be a significant supply source.
Or... we should be working on an updated electricity grid model _now_, so that excess renewable energy can be stored in the batteries of parked cars, and released back into the grid when the wind stops.
Enable this via tariffs that vary in real time depending on the level of renewable energy being generated.
Battery owners would be able to say how much of their capacity can be used as buffer storage, so if you're about to go on a long trip you can be sure of starting with a full battery.
