Hydrogen vs. Battery Electric Cars

Neither Hydrogen or electric. Ethanol or biodiesel. This would be after the E.R.O.E.I. for petroleum no longer makes it a viable resource. Downside is that a choice will need to be made to utilize land to grow crops for food or fuel. When the E.R.O.E.I. for petroleum no longer makes it a viable energy source this will cause a very significant reduction in world population anyway so choosing to grow crops for food or fuel will not be such a great dilemma.
