Biofuel commonly known as green fuel are products made from biological materials which can be used as fuels instead of fossil fuels. It is a type of renewable liquid fuel derived from plant and animal materials, which are found to be more eco-friendly than the widely-used fossil fuels that clout most of the world. People, world-wide are hunting for alternative energy sources and a green fuel has advanced as a promising fueling option for them in comparison to fossil fuels resources. Biodiesel, bioethanol and biomethanol are the most common biofuels. Following stated are the benefits and downside of biofuels:

Cost factor:
The chief benefit that biofuel provides us more than any other energy sources is its cost factor. Biofuel offers a low-priced solution to our energy needs in comparison to the ever increasing prices of crude oil. The reason why its cost is so low is that they are made from plant and animal waste.

Eco- friendly:
Biofuels are easily biodegradable and quite safer to knob than traditional fuels, making spills less dangerous and cheaper and also much easier to clean up. It is a natural product and do not cause damage to the environment when it is combusted. Comparatively they are less polluting which means they emit less carbon and thereby serve to the necessity of the world today.

Biodiesel is made from renewable resources such as vegetable oils, animal fats or cast-off greases. It is a renewable diesel operating like the traditional diesel. Biodiesel can be used in its untainted structure as a fuel for vehicles, but usually it is used as a diesel stabilizer in diesel-powered vehicles, which helps to diminish the levels of carbon monoxide, particulates and hydrocarbons. Biodiesel can be used single-handedly or can be combined with petrodiesel. In United States it’s regulated as mono-alkyl ester.

Environmental upshots:
In contemporary world where petrol has reached excessive prices and is diminishing in quantity, moreover causing harms to the environment; people are in search of substitutes which would solve their all above revealed problems. There are subsequent environmental benefits when choosing to use biodiesel over standard petroleum based diesel. They are as follows:

1. It Reduces Pollution-
Biodiesel lessens almost all forms of pollutants like carbon oxides, nitrogen oxides, carbon oxides, etc which contributes to air pollution. Biodiesel contains higher cetane rating than petrodiesel, which can help in improving the performance and crackdown emissions as compared to unrefined petro-diesel. Fossil fuels on other hand burns sulfur dioxide (SO2) and other elements that source the air to become polluted.
