I used that to respond to an earlier post to dispute his ration of 1 gallon of fuel used to 13 gallons of ethanol created, which is a pile of misinformation.

Now back to your point, what is it exactly? Are you saying they don’t use all of the energy input to come up with there ratio? With out seeing the study they used to come up with their final numbers I cannot say they did or did not.

Are you saying they don’t use all of the energy input to come up with there ratio?

Not when you are discussing fossil fuel ratio. By definition, it does not include inputs from items like electric power generated by nuclear, hydro or wind.

The department of energy produced their own brochure using data from Center for Transportation Research and Argonne National Laboratory.

http://www1.eere.energy.gov/vehiclesandfuels/pdfs/program/ethanol_brochure_color.pdf

They show the difference of total energy (left side below) ratio versus fossil fuel (center below) ratio.

When you look at the total energy needed to produce the fuel, the dept of energy claims it takes more to produce it than the fuel contains.
