But MORE "energy" was used for those 30 miles driven by battery compared to a gallon of gas. A gas tank...$50 is a LOT cheaper than $10,000 worth of batteries.
PRICE has NOTHING to do with it...we're not talking about price...we're talking about ENERGY.
Efficiency has everything to do with it...you claimed a battery can replace fuel. It will be as/more efficient.
Tell me HOW MUCH ENERGY goes into making/charging a battery and how much energy is used to deliver a gallon of gas. For the gas...it's 1/5th...20% of the energy contained in that gallon of gas was expended refining and delivering that gallon of gas.
For a lithium battery it's MINUS 32. 32X the energy contained in the battery is used to build/charge it. And EVERY time you recharge it...you go MORE negative because NO battery is 100% efficient.
It IS all about efficiency. Until we can build a battery that recharges itself with water and air...a battery CAN'T be more efficient.
