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.

Unlimited Production Resources:
Biofuel can be composed from extensive variety of materials like manure, crop waste, fungi and algae, whereas oil is a limited resource that comes from specific materials. Apart from this fact, these sources are available in plenty and can be potentially regenerated on an enormous scale.

Renewable and promotes Economic Encouragement:
Biofuels are easily renewable as new crops are persistently grown and the waste material gets collected. Fossil fuels on other hand takes thousands of years to be produced. Biofuels also helps kindle job opportunities as it is produced locally and thereby has prospective to provide employment to the unemployed. Biofuel production will also boost the demand for suitable biofuel crops, providing stimulation to the agriculture business.

However, biofuels also undergo many disadvantages; the chief amongst them is the low energy yield of the fuels. Critics recommend that the term "green fuel" is a misnomer, as a substantial amount of pollution is created when crops are processed into biofuel that may cause damage to the environment as like as current practices. Thus, greener ways ought to be found for processing and obtaining biofuel. Moreover manufacturing of fuel and proper irrigation of biofuel crops requires huge quantities of water which could possibly have an adverse effect on local and regional water resources.

Biofuel in Future:
Biofuel is undoubtedly a reliable alternative energy resource but certainly more developments and researches are essential to subdue its disadvantages and thereby making it appropriate for the consumers to use. They can then enjoy the benefits offered by this sustainable, renewable energy source to the whole.
