What is Sustainable biofuels?
'''Biofuels''' are [[Fuel|fuels]] from [[plant]] materials. They could reduce the price of [[oil]]. Some [[biofuel]]s can supply [[sustainable energy]]. Development of biofuels will help economic prospects in Africa, Latin America and Asia.<ref>[[The Royal Society]] (January 2008).
