KennyBobby, I need to wait to read your message, I just came home from Church and need to go back out, but I received an e-mail from my professor, he linked me: Corn vs Sugar Cane for Ethanol

which states:
All energy for the industrial process comes from bagasse burned in high pressure boilers, providing all thermal, mechanical and electrical energy needed, with at least 10% surplus electrical energy sold to the grid. Corn needs natural gas or fuel oil and electricity from the grid to supply its process-energy demands in the factory.

Ethanol yield (gallons/acre) for sugar cane under good tropical conditions is double that for corn. For all those reasons, sugar cane ethanol is seven times more energy efficient; its net energy, expressed as ERoEI, is 9:1 while corn ethanol has an ERoEI of only 1.3:1.
So, sugarcane produces more ethanol and produces its own energy, while corn requires outside energy to produce ethanol.
