| Abstract: | A life cycle energy assessment model of cassava-based fuel ethanol was established based on life cycle theory. The life cycle total energy, fossil fuels, and petroleum consumption, net energy yield, and overall energy utilization degree of cassava-based fuel ethanol were assessed. Compared with conventional gasoline, the life cycle total energy consumption of cassava-based fuel ethanol is higher about 22%, while the fossil fuels consumption, petroleum consumption, net energy yield, and overall energy utilization degree are lower about 54%, 96%, 45% and 8% respectively. The cassava-based fuel ethanol is a potentially significant green fuel for automobile. |
