"Put another way," Pimentel says, "about 70 percent more energy is required to produce ethanol than the energy that actually is in ethanol. Every time you make 1 gallon of ethanol, there is a net energy loss of 54,000 BTU." Ouch, we put more energy into making the sstuff than we can get out?
How much fossil fuel gets burned to do that?
Ethanol from corn costs about $1.74 per gallon to produce, compared with about 95 cents to produce a gallon of gasoline. I think he is talking market price here and not cost. If gas cost 95 cents to produce I don't think they could sell it for $1.15 and still pay for transport and advertising and gas-station attendants and industrial cleaning teams they bring in once a decade to disinfect the toilets.
The average U.S. automobile, traveling 10,000 miles a year on pure ethanol (not a gasoline-ethanol mix) would need about 852 gallons of the corn-based fuel. This would take 11 acres to grow, based on net ethanol production. This is the same amount of cropland required to feed seven Americans.
Or about 10 non-obese people, or an entire village of starving, dewy-eyed children
If all the automobiles in the United States were fueled with 100 percent ethanol, a total of about 97 percent of U.S. land area would be needed to grow the corn feedstock. Corn would cover nearly the total land area of the United States. Throwing the current feces and cement motif completely off
