"Adding up the energy costs of corn production and its conversion into
ethanol, 131,000 BTUs are needed to make one gallon of ethanol. One gallon
of ethanol has an energy value of only 77,000 BTUS. Thus, 70 percent more
energy is required to produce ethanol than the energy that actually is in
it. Every time you make one gallon of ethanol, there is a net energy loss of
"Ethanol from corn costs about $1.74 per gallon to produce, compared with
about 95 cents to produce a gallon of gasoline. "That helps explain why
fossil fuels-not ethanol-are used to produce ethanol", Pimentel says. "The
growers and processors can't afford to burn ethanol to make ethanol. U.S.
drivers couldn't afford it, either, if it weren't for government subsidies
to artificially lower the price". "
I've also read that if 100% of our current corn production was devoted to
ethanol production it would account for somthing like 15% of our fueling
need. To provide 100% of our fueling need through corn ethanol it would take
every farm that currently exists in the country to stop everything they are
doing and produce corn exclusively. Sounds viable... yeah.
Of course it's also been proven that a Hummer H2 is better for the
environment then a Toyota Prius. Agreed it's all just a smoke screen. IMO
electics or hybrids that are solar recharged are a good way to go, but then
solar cells are expensive too.
