A 1.10 Why does ethanol arouse so much interest worldwide?
Today, the greater interest in the use of ethanol as an energy source results from the need to replace part of the oil that is used and reduce greenhouse gas emissions. The possibility to reduce the local pollution in urban centers by adding ethanol to gasoline, while improving gasoline quality thanks to the anti-knock power of ethanol, is also an important reason for such interest. The work carried out in Brazil is particularly important because it has demonstrated that very significant production levels can be attained at competitive costs.
