12% higher in energy content.
Ethanol = 77,000 BTU/gal
Gasoline = 124,000 BTU/gal
Diesel = 139,000 BTU/gal
The problem with the cost of diesel is the short suppy of low sulfur diesel, not the cost of production or the heat content.
But yes, diesel has been by far the least expensive fuel for years in terms of heat content per $. And on top of that, diesel engines run higher compression ratios than spark ignition gasoline cars.
