Energy Consumption

Energy consumption is dependent on the type of feedstock, the production process used, and the level of technology employed.The potential environmental benefits of ethanol production are directly related to its net energy balance.

If energy consumed in the production of ethanol is generated through the use of "dirty" fuels such as coal, the overall environmental impact is less positive. The net energy gain and environmental benefits of ethanol blended fuel are comprimised when "dirty" fuels are used to power any of the various stages of the production process.
