The substitution of fossil fuels by biofuels is being stimulated by governments because of the perspective of exhaustion of world oil reserves, in consequence of constant price rising and also because of environmental impacts. It is based on this perspective that this research work was realized, aiming to develop a search of information related to it, mainly exposing environmental, economical and social impacts of fossil fuels and biofuels that naturally are the substitutes of these. Through the research developed, it was noticed that there are many convergent information related to the positive side of substituting oil by biofuels, as also was detected a set of researches that show adverse information. These researches alert to a set of problems that must be solved before a total substitution aiming sustainability, such as: familiar agriculture incentive; delimitation of properties’ size; formation of cooperatives; creation of a national network of thousands of micro-plants integrated by cooperatives of small and medium rural producers; and so on.
