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 and so on by yeast fermentation. Wood items can also be transformed into Biofuels.

The from these items includes both benefits and drawbacks.

Advantages of Biofuels:

Ecological Benefits: The main expectation of using 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 cars. It lowers the green home significantly compared to other nonrenewable fuel sources.

First generation biofuels can conserve carbon emissions about 60% compared to fossil fuels whereas the 2nd generation biofuels are much better than first generation fuels. It uses carbon emission cost savings approximately 80%. Recently, UK Government publication specified that biofuels can minimize emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel‘s cost decreases substantially if the biofuel production technology spreads worldwide. The biofuels are established locally which automatically enhances the rural advancement as the technology depends primarily on manual power. The quick increase of biofuel at the same time increases the production of these oil crops which stimulates the agricultural industry. The UK government has announced that it reduces the tax for lorries which are environmentally friendly. Additionally, the sturdiness of the engine increases while using these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is eco-friendly and much safer to manage 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 environments. More forests have been destroyed in Asian nations for the plantation. The producing system of these biodiesel indeed needs nonrenewable fuel sources which produces more carbon emissions. High initial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are normally unwanted 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
