Rather than focusing on other consumables, I prefer to consider miles per gallon of anti-freeze, which is poisonous to puppies and kittens.
My VW Beetle, and it's eventual electric replacement will remain at infinity divided by zero.
Considering electricity, I pay 5¢ per kilowatt-hour. If I were to drive across the bridge into the next burg over, the cost of a recharge would double. If I were to venture outside the PNW, it would triple. And more coal miners would die.
