Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally includes oil namely jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn etc by yeast fermentation. Wood products can likewise be converted into Biofuels.

The acquired Biofuels from these products contains both benefits and drawbacks.

Advantages of Biofuels:

Ecological Benefits: The primary expectation of using the biofuel is to be carbon neutral, less of CO and Sulfur, as it is made from natural deposits, and it is sustainable and pure fuels so it is excellent for automobiles. It minimizes the green house substantially compared to other nonrenewable fuel sources.

First generation biofuels can save carbon emissions about 60% compared to fossil fuels whereas the 2nd generation biofuels are better than very first generation fuels. It uses carbon emission savings up to 80%. Recently, UK Government publication mentioned that biofuels can decrease emissions by 50-60%. Efficiency of the engine increases by using biodiesel as the lube.

Economical: The biofuel's rate reduces considerably if the biofuel production innovation spreads worldwide. The biofuels are developed locally which instantly boosts the rural development as the technology depends generally on manual power. The fast boost of biofuel all at once increases the production of these oil crops which stimulates the farming market. The UK government has revealed that it lowers the taxation for cars which are eco-friendly. Additionally, the resilience of the engine increases while using these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are eco-friendly and it is biodegradable and more secure to manage and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more environments. More forests have been destroyed in Asian nations for the plantation. The producing mechanism of these biodiesel certainly needs nonrenewable fuel sources which produces more carbon emissions. High initial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those odours are typically unwanted and biofuels plants can not be setup near the big .

Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking
