    All biomass goes through at least some of these steps: it needs to be grown, collected, dried, fermented, distilled, and burned. All of these steps require resources and an infrastructure. The total amount of energy input into the process compared to the energy released by burning the resulting ethanol fuel is known as the energy balance (or "energy returned on energy invested"). Figures compiled in a 2007 report by National Geographic Magazine point to modest results for corn ethanolproduced in the US: on

  • Ethanol explained U.S. Energy Information Administration

    2019-10-23· Cellulosic ethanol is a large potential source of fuel ethanol. Ethanol can also be produced by breaking down cellulose in plant fibers. This cellulosic ethanol is considered an advanced biofuel and involves a more complicated production process than fermentation. While large potential sources of cellulosic feedstocks exist, commercial production of cellulosic fuel ethanol is relatively small.
