Gee, who was it here that said that it takes more energy to make
ethanol
than it produces?

I did, and it is true if you add in all of the agricultural energy
such as fertilizer production, etc.
It was true, not anymore.

Well, halleluiah and praise be to the corn gods. Cheap perpetual
energy. Oh, and by the way, the science community better get busy
re-writing the laws of physics.
I posit that "perpetual" energy really isn't relevant. If you were an
early settler to this continent, and spent a day cutting down a tree
and
sawing it into firewood, you had a source of energy for your cooking
and
heating fires that would last a long, long time, and would certainly
provide more energy in terms of BTUs and other measurements than you
expended.
---------------------------------
The energy expended by the settler is not all the energy involved.
It's only that used in the harvesting of the tree.
iBoater previously claimed that it takes less than a gallon of fossil
fuel to produce a gallon of ethanol. He's now claiming that all the
energy consumed in the growing, harvesting and production of the corn
(or sugar) for a gallon of ethanol is less than the energy the gallon
of ethanol will produce as a fuel.
I say nonsense.
iStupid doesn't have a leg to stand on.

Because a gallon of ethanol contains less energy than a gallon of gasoline, the production
cost of ethanol must be multiplied by a factor of 1.5 to make an energy-cost comparison with
gasoline. This means that if ethanol costs $1.10 per gallon to produce, then the effective
cost per gallon to equal the energy contained in a gallon of gasoline is $1.65. In contrast,
the current wholesale price of gasoline is about 90 cents per gallon.
