"Alcohol" is a general descriptor of a chemical class, not any particular
molecule.  Dragsters used methanol (a 1-carbon alcohol), and biofuels are
normally ethanol (2-carbon).  These alcohols have the advantage of high
octane ratings, and racers liked the detonation resistance fershure.  I'm
not sure how much "fuel" is methanol anymore -- others can probably update
us there.

>From Wikipedia:
One liter of ethanol contain 21.1 MJ, a liter of methanol 15.8 MJ and a
liter of gasoline approximately 32.6 MJ. In other words, for the same
energy content as one liter or one gallon of gasoline, one needs 1.6
liters/gallons of ethanol and 2.1 liters/gallons of methanol.

The one to watch is butanol -- the 4-carbon alcohol.  This one has energy
density similar to gasoline and easier storage/transport.  The biofuels
guys are working now on conventional or enzymatic cracking techniques to
take ethanol to butanol.
