Since Diesel is more dense, holds more energy than gasoline in weight, and requires less refining, then why does it cost 10%-15 % more at the pump ?
Is it strictly the amount of Road Taxes ?
That three little diamonds, just above the 0.00, represent different types of batteries. The one on the right is probably Lithium Ion. So you get an idea of what you’re dealing with. That’s why running the heater on an electric car is a battery-killer, while running the heater on a gas car is free heat (that would have been rejected by the engine or radiator anyway).
So ethanol is heavier than gasoline, and is more dense according to the graph.
But also ethanol has fewer Btu’s for energy.
So , our $4.00 per gallon ethanol gas would cost us approximately $4.35 as a pure gas ?
The $4.00 per gallon ethanol gas doesn’t include government subsidy to the ethanol industry .
Personaly, I would rather have corn for feed and nutrition of humans and domestic annimals during a drought,
rather than the intransigent EPA trying to get 15% ethanol gas usage during a drought.
