Ethanol has to be distilled, requiring heat.
The energy (BTU’s) required to heat the corn to the proper boiling point to distill ethanol is in excess of the energy (BTU’s) stored in the ethanol.
It makes sense to distill corn into moonshine, potatoes into vodka and grain or peat into whiskey as the product gains in value.
Ethanol is distilled for votes.
While I am no fan of the Ethanol Mandate, the claim above is not true.
