Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally consists of 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 also be transformed into Biofuels.

The acquired Biofuels from these items includes 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 resources, and it is eco-friendly and pure fuels so it is good for vehicles. It lowers the green house significantly compared to other fossil fuels.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the 2nd generation biofuels are much better than first generation fuels. It uses carbon emission savings as much as 80%. Recently, UK Government publication stated that biofuels can lower emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel's price reduces considerably if the biofuel production innovation spreads worldwide. The biofuels are developed in your area which instantly boosts the rural development as the technology depends primarily on manual power. The fast increase of biofuel simultaneously increases the production of these oil crops which stimulates the farming industry. The UK federal government has announced that it lowers the tax for cars which are environment-friendly. Additionally, the toughness 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 safer to manage and less harmful than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more environments. More forests have actually been ruined in Asian countries for the plantation. The producing mechanism of these biodiesel indeed needs fossil fuels which produces more carbon emissions. High initial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are generally unwanted and biofuels plants can not be setup near the large communities.

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