Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally consists of oil namely 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 acquired Biofuels from these products contains both advantages and downsides.

Advantages of Biofuels:

Ecological Benefits: The primary 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 is good for vehicles. It decreases 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 much better than first generation fuels. It offers carbon emission savings up to 80%. Recently, UK Government publication specified that biofuels can lower emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's rate reduces significantly if the biofuel production innovation spreads out worldwide. The biofuels are established in your area which immediately improves the rural development as the technology depends mainly on manual power. The rapid boost of biofuel at the same time increases the production of these oil crops which stimulates the farming industry. The UK federal government has announced that it lowers the taxation for vehicles which are eco-friendly. Additionally, the resilience of the engine increases while using these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is biodegradable and much safer to handle and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will tossed away more environments. More forests have actually been damaged in Asian countries for the plantation. The producing mechanism of these biodiesel certainly requires nonrenewable fuel sources 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 generally unfavorable 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
