New Math

40 bushels per metric ton times 256280000 Metric tons per year times 2.8 gallons per bushel equals about 30 billion gallons of ethanol per year.

divided by 385 million gallons per day equals 78 days.

Extra credit: multiply the ethanol production by the ratio between the energy of ethanol and the energy of gasoline.

But

Will we deplete human and animal food supplies by using corn and other grains for fuel production?

No, actually the production of ethanol from corn uses only the starch of the corn kernel, all of the valuable protein, minerals and nutrients remain. One bushel of corn produces about 2.7 gallons of ethanol AND 11.4 pounds of gluten feed (20% protein) AND 3 pounds of gluten meal (60% protein) AND 1.6 pounds of corn oil.
