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

The obtained Biofuels from these items includes both benefits and drawbacks.

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 sustainable and pure fuels so it benefits automobiles. It reduces the green home considerably 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 offers carbon emission savings up to 80%. Recently, UK Government publication mentioned that biofuels can reduce emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel's price reduces significantly if the biofuel production innovation spreads worldwide. The biofuels are developed in your area which automatically boosts the rural advancement as the innovation depends primarily on manual power. The fast boost of biofuel at the same time increases the production of these oil crops which stimulates the farming market. The UK government has announced that it the tax for automobiles which are environment-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 eco-friendly and it is biodegradable and 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 got rid of more habitats. More forests have been ruined in Asian countries for the plantation. The producing mechanism of these biodiesel undoubtedly needs nonrenewable fuel sources which produces more carbon emissions. High initial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those odours are usually undesirable and biofuels plants can not be setup near the big communities.

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