2^nd Generation biofuel	· produced from non-food crops such as wood, organic waste, food crop waste and specific biomass crops · Cellulosic technology is used · Jatropha based biofuel · More available biomass, less controversial · High capital costs
3^rd Generation fuel	· Based on the energy extracted from algae. · Algae are cultured at low cost · Entirely renewable feedstock
4^th Generation biofuel	· Way of capturing and storing CO₂ · Aims at capturing more carbon and producing sustainable source of energy

Biofuels can address the issue of energy deficiency and crisis faced by various countries. The need of the hour is to make the technology more competitive so that energy can become accessible to common masses.
