Fossil fuels are presently used for residential, commercial, industrial and transportation purpose and even to generate electricity. The wide-scale use of fossil fuels ranges from coal at first stage and petroleum later, and even to fire steam engines, which enabled the industrial revolution to evolve. There are a number of problems associated with fossil fuel usage. Most of which stem from the by-products created when they are burned to create energy. Biofuels-liquid fuels derived from renewable resources such as plant or animal materials - enter the market, driven by factors such as oil price hikes and the need for increased energy security. Based on this perspective, the aim of the present research work was to look at biofuel as an alternative source of energy for transportation. The technological analysis was carried out by studying the process involved in the biofuel production. The study is continued further with the comparison of quality, performance and emission intensity level of biofuel with that of conventional fuel, with respect to the transportation purpose.
