Depletion of petroleum based fuels has been a lot of concern among the governments and researchers around the world. Usage of biofuels in place of the conventional fuels is showing rapid growth because of the favourable characteristics like better performance and time improved emission characteristics. Present paper discusses about different available biofuels and their effectiveness in replacing fossil fuels and also how they affect the technological growth. Different works are compared to bring out the actual scenario with respect to the performance, emission, availability, production and preparation methods. It is observed that much effort is made by the stake holders in order to see biofuels as a viable alternative and as a future fuel for internal combustion engines. Performance improves slightly with the usage of biofuels and reduced emission characteristics may be logical to observe. But it may not be appreciable, considering the series of production processes involved. It still requires lot of time to commercialize and produce biofuels in mass. Also, there have been constraints like the availability of raw materials for the same. It is concluded that biofuels do play significant role in the days to come provided there is much more effort from researchers to simplify the technology in making biofuel as sustainable and cost effective with at least comparable performance.
