1# The use of ethanol-blended fuels such as E85 (85% ethanol and 15% gasoline) can reduce the net emissions of greenhouse gases by as much as 37.1%, which is a significant amount.
2# Exhaust gases of ethanol are much cleaner, it burns more cleanly (more complete combustion)
3# Positive energy balance – Depending to the type of raw stock it can vary from 1.24 to 8. The output of energy during the production is more than the input. (controversial)
