People are trying left right and center to produce ethanol and other biofuels from some other sources which are as varied as colours in rainbow. Algae, Biowaste, Biomass, cultivation in sea and what not.
Sooner or later we shall find some solution to it. One thing that strikes me is that in India cultivation & production of biofuels is picking up but almost every place used for its cultivation is/previously was barren or unutilized. Actually government isn't supporting purchase of them and hence its totally end user oriented.
