Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally contains oil namely Jatropha, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn and so on by yeast fermentation. Wood items can likewise be converted into Biofuels.

The obtained Biofuels from these products contains both advantages 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 deposits, and it is renewable and pure fuels so it benefits cars. It reduces the green house considerably compared to other fossil fuels.

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

Economical: The biofuel's cost decreases considerably if the biofuel production innovation spreads worldwide. The biofuels are developed locally which immediately boosts the rural development as the technology depends generally on manual power. The rapid boost of biofuel all at once increases the of these oil crops which promotes the farming industry. The UK federal government has revealed that it decreases the tax for automobiles which are environmentally friendly. Additionally, the durability of the engine increases while using these combustible fuels in engines.

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

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will got rid of more environments. More forests have been damaged in Asian nations for the plantation. The producing mechanism of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High preliminary financial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those odours are typically 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
