Therefore,it is necessary to search for an alternative source of gaseous fuel which has the potential to meet the present and future energy needs. Use of fossil fuel releases greenhouse gases into atmo-sphere results in global warming; this leads to seek for bioenergy. The bioenergy will have the possibility of covering more than 50% of the renewable supply oft he fixed goals by the year2020. Biofuels, in conjunction to theirpositivecarbon balance with regards to fossil fuels,also representa significant potential for sustainability because they can be generated from locally available renewable material.The current debate over first generation biofuels produced from food crops has pinnedalotofhope on second generation biofuels produced majorly fromcrop,forest residues andnon-foodenergycrops.Policies Designed To Support
the promotion of second generation biofuels must be carefully developed iftheyaretoavoidunwantedconsequencesand
