With the increase in the usage of fossil fuels the quantity of fossil fuels is found to be rapidly declining.
Poisonous effervesces released by the incomplete combustion of fossil fuels pose a great threat to the life on earth with a drastic change in weather and unexpected climate phenomena.
The major problem with the usage of diesel is not the pollution but the decline in its natural reserves which pose threat to the future generations and hence the sustainable sources of energy comes into picture and diesel being the major source of energy all around the world. It has to be substituted with alternative energy forms.
Bio diesel refers to a vegetable oil- or animal fat-based diesel fuel.
Bio diesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone, or blended with petro-diesel. Biodiesel can also be used as a low carbon alternative to heating oil.
