Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally consists of oil specifically jatropha curcas, 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 transformed into Biofuels.

The obtained Biofuels from these products includes both benefits and disadvantages.

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 is excellent for autos. It reduces the green house significantly compared to other fossil fuels.

First generation biofuels can save carbon emissions about 60% compared to fossil fuels whereas the second generation biofuels are better than first generation fuels. It uses carbon emission savings as much as 80%. Recently, UK Government publication specified that biofuels can reduce emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's rate reduces considerably if the biofuel production technology spreads out worldwide. The are established in your area which immediately enhances the rural development as the technology depends generally on manual power. The rapid increase of biofuel simultaneously increases the production of these oil crops which stimulates the agricultural industry. The UK federal government has actually announced that it lowers the taxation for automobiles which are environmentally friendly. Additionally, the durability of the engine increases while utilizing these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are eco-friendly and it is eco-friendly and safer to deal with and less harmful than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more environments. More forests have been ruined in Asian countries for the plantation. The producing system of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High initial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are generally undesirable 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
