While there are clear benefits in alternative sources of energy such as ethanol, its future as a viable competitor to oil remains uncertain due to number of concerns that range from environmental trade-offs, economic competitiveness, sustainability, etc. One major stumbling block for the ethanol industry is the extent to which the land intensity of current biofuel production can be reduced. While to be competitive with oil, current rates of production need to increase significantly, such a huge increase is not viable due to present intensity of land use. The good news is that cellulosic ethanol is an alternative energy resource that can potentially resolve this issue, and significantly reduce world’s dependence on oil with less negative consequences for the environment than other sources of energy.
