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

The acquired Biofuels from these products contains both advantages 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 sustainable and pure fuels so it is great for cars. It reduces the green house considerably compared to other nonrenewable fuel sources.

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

Economical: The biofuel's price reduces considerably if the biofuel production innovation spreads out worldwide. The biofuels are established in your area which instantly improves the rural advancement as the innovation depends generally on manual power. The rapid increase of biofuel simultaneously increases the production of these oil crops which promotes the agricultural market. The UK federal government has announced that it minimizes the tax for vehicles which are eco-friendly. Additionally, the sturdiness of the engine increases while using these flammable fuels in .

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is biodegradable and safer to handle and less hazardous 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 destroyed in Asian countries for the plantation. The producing system of these biodiesel certainly needs fossil fuels which produces more carbon emissions. High preliminary financial investment is required for the biodiesel production.

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

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