IMO, wrong line of thinking. Profits should have nothing to do with a nations energy wants. Sustainability and cost per unit should be the only concerns.
..Brazil supports this population of ethanol-burning automobiles with large national infrastructure that produces ethanol from domestically grown sugar cane. Sugar cane not only has a greater concentration of sucrose than corn (by about 30%), but is also much easier to extract. The bagasse generated by the process is not wasted, but is used in power plants to produce electricity.
Oh thank you. (Sorry a little late on catching up on some old readings). :thumbsup:I know all this already.
