However, the major flaw with corn-based ethanol is that the production process requires buring of 1L of petroleum to make 1L of ethanol! Thus, any benefit derived by using ethanol is fully nullified.
At least in Brazil, they are using sugarcane-based ethanol, which uses significantly less energy to make 1L of ethanol than corn-based ethanol.
The US/European politicians are doing a good job misleading the public about corn-based ethanol as a "green" alternative energy source.
As more and more corn is diverted for ethanol production, what will happen to the world's food supply?
