What about Brazilian cane-based ethanol? The sugar conversion efficiency, I'm not certain this is the right term, is significantly higher than that of corn or beet but logistics deficiencies in the country may make it more expensive and less green.
- thinkcontext 5y agoThe term you are looking for is Energy Return On Investment (EROI). This is the amount of useful energy you get divided by the amount of energy you spent to get it. The figure I've seen most often for ethanol from corn is 1.25 (though some people argue its less than one), which is not very good. When made from Brazilian sugarcane its 8 which is amazing.
