Biofuels is the promising source of energy for future fuel needs. 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 and so on by yeast fermentation. Wood products can likewise be converted into Biofuels.

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

Advantages of Biofuels:

Ecological Benefits: The main expectation of utilizing the biofuel is to be carbon neutral, less of CO and Sulfur, as it is made from natural resources, and it is renewable and pure fuels so it benefits cars. It reduces the green house substantially compared to other nonrenewable fuel sources.

First generation biofuels can save carbon emissions about 60% compared to fossil fuels whereas the second generation biofuels are better than first generation fuels. It offers 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 rate reduces significantly if the biofuel production innovation spreads out worldwide. The biofuels are established in your area which immediately boosts the rural development as the innovation depends generally on manual power. The fast boost of biofuel concurrently increases the production of these oil crops which promotes the farming industry. The UK federal government has announced that it lowers the tax for lorries which are environmentally friendly. Additionally, the resilience of the engine increases while utilizing these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are eco-friendly and it is eco-friendly and much safer to deal with and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more habitats. More forests have been ruined in Asian countries for the plantation. The producing system of these biodiesel undoubtedly requires 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 normally unfavorable 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
