Energy plays a vital role in the economic growth of any country. Current energy supplies in the world are unsustainable from environmental, economic, and societal standpoints. All over the world, governments have initiated the use of alternative sources of energy for ensuring energy security, generating employment, and mitigating carbon dioxide emissions. Biofuels have emerged as an ideal choice to meet these requirements. Today, converting photosynthetic bio-mass (plants, grasses, and algae) into fuel is the most common route adopted for creating alternatives to crude oil. However, the problem lies in growing huge quantities of biomass, as nearly all bio-mass feedstock make use of the same limited resources (arable land, fresh water, and fertilizers) which go into agriculture. This means biofuels have certain limitations that need to be addressed before they can be considered as a sustainable solution.
