Well I meant that question purely from the available energy aspect of the source. Let me rephrase.

Is it fair to display the inefficiency of a gas car by saying it takes about 4000lb of lead acid to equal a gallon of gas under normal driving conditions?

I know that due to the efficiency of EV's it does not take that much lead to go 30 miles for example but that's kind of taking away from the EVs.

This way if we tell the average joe that we carry a battery pack with the energy equivalent of 1/3 of a gallon of gas and can still go 40 miles ( I'm just making these numbers up ) maybe they get to think about it!?
