Is Ethonol the future??

The National Corn Growers Association (NCGA) is disputing a study
conducted by Cornell University's David Pimentel and University of
California, Berkeley, professor Tad Patzek that states ethanol has a net energy
balance loss of 29%. That study has gained attention in recent days in
a variety of media outlets. NCGA cites a different study showing that
ethanol has a substantial net energy gain of at least 67%.

Patzek and Pimentel included the cost of inputs for creating ethanol -
right down to the diesel fuel used to power the tractors, and the
natural gas used to create fertilizer. Their calculations say ethanol offers
about 76,000 BTUs per gallon, but producing it from corn uses about
98,000 BTUs. They say corn-based ethanol requires 29% more fossil energy
than the fuel produced.
