Biofuels is the promising source of energy for future fuel needs. Biodiesel can be developed from growing plants which of oil namely jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn etc by yeast fermentation. Wood products can also be transformed into Biofuels.

The acquired Biofuels from these products includes 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 resources, and it is renewable and pure fuels so it is great for automobiles. It minimizes the green home considerably compared to other fossil fuels.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the 2nd generation biofuels are much better than very first generation fuels. It provides carbon emission savings as much as 80%. Recently, UK Government publication mentioned that biofuels can minimize emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's rate reduces substantially if the biofuel production innovation spreads worldwide. The biofuels are established locally which automatically boosts the rural development as the innovation depends primarily on manual power. The fast boost of biofuel simultaneously increases the production of these oil crops which stimulates the farming industry. The UK government has actually revealed that it minimizes the tax for cars 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 eco-friendly and it is naturally degradable and more secure to handle and less harmful than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will got rid of more environments. More forests have been ruined in Asian countries for the plantation. The producing system of these biodiesel certainly needs nonrenewable fuel sources which produces more carbon emissions. High preliminary financial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those smells are typically unwanted 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
