Biofuels is the appealing 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 drawn out from sugar crops like sugarcane, sugar beet, maize, corn etc by yeast fermentation. Wood items can also be converted into Biofuels.

The obtained Biofuels from these products contains both benefits 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 resources, and it is sustainable and pure fuels so it benefits autos. It reduces the green home significantly compared to other fossil fuels.

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

Economical: The biofuel's cost decreases considerably if the biofuel production technology spreads worldwide. The biofuels are developed in your area which immediately improves the rural development as the innovation depends generally on manual power. The rapid increase of biofuel at the same time increases the production of these oil crops which stimulates the agricultural market. The UK government has announced that it minimizes the taxation for vehicles which are environment-friendly. Additionally, the durability of the engine increases while utilizing these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is biodegradable and safer 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 got rid of more habitats. More forests have been destroyed in Asian nations for the plantation. The producing mechanism of these biodiesel certainly requires fossil fuels which produces more carbon emissions. High initial financial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those odours are usually unfavorable 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
