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

The obtained Biofuels from these items includes both benefits and disadvantages.

Advantages of Biofuels:

Ecological Benefits: The main expectation of utilizing the biofuel is to be carbon neutral, less of CO and Sulfur, as it is made from natural deposits, and it is renewable and pure fuels so it benefits automobiles. It minimizes the green house to other fossil fuels.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the second generation biofuels are much better than first generation fuels. It uses carbon emission cost savings up to 80%. Recently, UK Government publication stated that biofuels can minimize emissions by 50-60%. Efficiency of the engine increases by using biodiesel as the lube.

Economical: The biofuel’s cost reduces substantially if the biofuel production innovation spreads out worldwide. The biofuels are established in your area which instantly enhances the rural development as the technology depends generally on manual power. The rapid increase of biofuel simultaneously increases the production of these oil crops which promotes the farming market. The UK government has revealed that it decreases the taxation for lorries which are environment-friendly. Additionally, the sturdiness of the engine increases while using these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are eco-friendly and it is naturally degradable and more secure to deal with and less dangerous than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more habitats. More forests have been damaged in Asian countries for the plantation. The producing mechanism of these biodiesel indeed requires nonrenewable fuel sources which produces more carbon emissions. High initial financial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are usually undesirable and biofuels plants can not be setup near the big neighborhoods.

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