I think I have the answer. Their solution is to require auto makers to allow bi-directional charging for electric vehicles so that when you hook your car up for a charge, if they happen to need the energy at the time they will instead drain your cars battery to borrow your juice that you once borrowed from them, and then charge the car once their schedule permits, or the black-outs are over.
I am just wondering at what point we walk outside straight into the Mad Max movie set, for real!
