Reply #29: the 51 cent excise tax credit per gallon of ethanol blended goes to the Oil refinery doing the

blending. None of it goes to the ethanol producer.


Farrell and Kammen study stated that two s

"Two of the studies stand out from the others
because they report negative net energy values
and imply relatively high GHG emissions and
petroleum inputs (11, 12). The close evaluation
required to replicate the net energy results showed
that these two studies also stand apart from the
others by incorrectly assuming that ethanol
coproducts (materials inevitably generated when
ethanol is made, such as dried distiller grains with
solubles, corn gluten feed, and corn oil) should
not be credited with any of the input energy and
by including some input data that are old and
unrepresentative of current processes, or so
poorly documented that their quality cannot be
evaluated."

Any paper that includes data inputs that are not documented is not a legitimate paper - especially since Pimentel and Patzek have been doing this sort of thing for years.
