I'll take a citation of an authoritative study over an individual's
claim, anyday. I notice you don't provide any, although you seem to be
claiming UC-Berkeley is shilling for Big Oil? LOL!

More details below from the study done by Berkeley students (which was
the precursor to the paper mentioned in the article I earlier cited).
Here's a link to the actual paper:
http://petroleum.berkeley.edu/papers/patzek/EthanolFromCorn.htm

"Patzek said that studies showing energy gain do not take into account
the amount of energy stored in the corn. "The energy stored in the corn
is not free," he said. "To grow the corn, you've used up soil and
water. We must also account for the disposal of waste water polluted by
nitrogen and phosphate fertilizers, as well as by pesticides and
herbicides."

"When calculating the net energy loss, Patzek and his students took
into account the energy equivalent contained within one bushel of corn.
According to the report, it takes a total of 0.87 gallons of gasoline
equivalent to grow one bushel of corn, which itself contains 3.17
gallons of gasoline equivalent energy. That calculation includes the
fossil energy expended from the use of fertilizer, pesticides,
machinery, irrigation and other inputs in corn production." -
