It's hard to falsify the claim (and what's the point?), because for the decision to be rational we need to both know what the energy requirements are, what the price of gas and batteries are, how much we value the environment/diminished CO2 (and how much of it would be saved), etc. Unless you mean the claim is "batteries can suffice", but without a price tag it's pretty uninteresting as a claim.
