Enabling homeowners to use their vehicles as backup when the power goes down would reduce the social impacts of large-scale blackouts. It also would give utilities more time to restore service — especially when there is substantial damage to power poles and wires, as occurred duringPower companies will still have to spend money building and maintaining the grid to provide reliable service.
