fuel efficiency

jp l questioned:

Why they promote corn and additional grains as sources as a substitution for sugarcanes which have at smallest amount 3X more efficient ethanol? Why use something will erode soil with the need of bounty of fertilizers while sugarcane only demand modest? Are they really for the background or just plain green? Perhaps they really work for fossil-fuel corporations to prevent ethanol efficiency compelling over?
