Sugar cane ethanol it's way more efficient way to produce ethanol. Corn ethanol produces a X value of ethanol energy, but about 80% or more of energy it's used in the production itself, calculating in energetic ways.
Corn have few sugar while sugarcane have a lot more sugar, in terms of production per hectare.
Brazil have decades of experience producing sugarcane ethanol, and I remamber than some USA authorities was interested in learn.
I wonder why no ocnspiracy theory had raised yet, about saudi oil attack. They should be saying crazy things like about the attacks be ordered by USA oil companies to raise the prices of oil on USA.
