Biofuels is the promising source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally includes oil namely 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 includes both advantages and downsides.

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 vehicles. It reduces the green house considerably compared to other fossil fuels.

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

Economical: The biofuel's price decreases significantly if the biofuel production technology spreads worldwide. The biofuels are developed in your area which immediately improves the rural development as the innovation depends mainly on manual power. The quick boost of biofuel simultaneously increases the production of these oil crops which stimulates the farming market. The UK government has announced that it decreases the tax for automobiles which are environment-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 renewable and it is biodegradable and much safer to manage and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more habitats. More forests have been destroyed in Asian nations for the plantation. The producing mechanism of these biodiesel certainly 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 typically undesirable 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
