N.Y. Times article (reg. req'd)
With Big Boost From Sugar Cane, Brazil Is Satisfying Its Fuel Needs includes the perhaps self-serving:
For each unit of energy expended to turn cane into ethanol, 8.3 times as much energy is created, compared with a maximum of 1.3 times for corn, according to scientists at the Center for Sugarcane Technology here and other Brazilian research institutes.
As I stated
before regarding another article, the N.Y. Times claims that Brazil is oil-independent because of
its development of ethanol; that begs the question of how much
energy was needed to produce the ethanol and
other concerns. Further as
another article points out:
Gasoline with or without MTBE can be shipped in large quantities through an extensive network of pipelines. But ethanol, which tends to corrode pipelines, must be transported on trucks, trains and barges in relatively small batches to storage terminals where it is then blended with gasoline.
