DisadvantageEthanol has a lower heat of combustion (per mole, per unit of volume, and per unit of mass) that petroleumLarge amounts of arable land are required to produce the crops required to obtain ethanol, leading to problems such as soil erosion, deforestation, fertiliser run-off and salinityMajor environmental problems would arise out of the disposal of waste fermentation liquors.Typical current engines would require modification to use high concentrations of ethanolAdvantage
Unlike petroleum, ethanol is a renewable resourceEthanol burns more cleanly in air than petroleum, producing less carbon (soot) and carbon monoxideThe use of ethanol as opposed to petroleum could reduce carbon dioxide emissions, provided that a renewable energy resource was used to produce crops required to obtain ethanol and to distil fermented ethanol
