Bio fuels and bio diesels are the possible environmental friendly alternative sources of energy, for the predominantly used fossil fuels. Biofuel has been in use worldwide particularly in Europe. Biofuel can be produced from oilseed plants like oil palm (in Malaysia and Indonesia), coconut (in the Philippines, Vanuatu and Marshall Islands), rapeseed (in Europe and Canada) and soybean (in the U.S.). It also can be produced from jatropha seeds, pongamia seeds or from any other non edible oil seeds. Bio fuels reduce the dependency on imported petroleum products, save valuable foreign exchange as well as create employment opportunities in agricultural sector by way of value added agricultural products.
Bio diesel is the only alterative fuel that can be used directly in existing diesel engine with no modifications. It has similar properties of petroleum diesel fuel. Therefore, biodiesel can also be blended and used in any ratio with petrol diesel fuels. In the United States alone, many federal and state fleet vehicles are already running on biodiesel blends with the existing diesel engines. The amount of bio diesel blended into petroleum diesel fuel can fluctuate such as 10%, 20% or more percentage, based on the price of vegetable oil and crude oil at that time.
