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

The obtained Biofuels from these products includes both advantages and disadvantages.

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 excellent for cars. It lowers the green house 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 much better than very first generation fuels. It provides carbon emission cost savings as much as 80%. Recently, UK Government publication stated that biofuels can by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel's cost reduces significantly if the biofuel production innovation spreads worldwide. The biofuels are established in your area which instantly enhances the rural development as the innovation depends generally on manual power. The quick boost of biofuel at the same time increases the production of these oil crops which promotes the farming market. The UK government has announced that it decreases the taxation for automobiles which are eco-friendly. Additionally, the sturdiness of the engine increases while utilizing these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are renewable and it is eco-friendly and more secure 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 been ruined in Asian nations for the plantation. The producing mechanism of these biodiesel certainly needs nonrenewable fuel sources which produces more carbon emissions. High preliminary financial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those odours 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
