Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally consists of oil particularly jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out from like sugarcane, sugar beet, maize, corn and so on 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 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 eco-friendly and pure fuels so it benefits automobiles. It reduces the green home considerably compared to other fossil fuels.

First generation biofuels can conserve carbon emissions about 60% compared to fossil fuels whereas the second generation biofuels are much better than first generation fuels. It provides 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 lubricant.

Economical: The biofuel's price reduces substantially if the biofuel production technology spreads out worldwide. The biofuels are developed locally which immediately improves the rural development as the technology depends primarily on manual power. The rapid boost of biofuel at the same time increases the production of these oil crops which promotes the farming industry. The UK federal government has revealed that it minimizes the tax for cars which are environmentally friendly. Additionally, the sturdiness of the engine increases while utilizing these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is naturally degradable and much safer to manage and less dangerous than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more environments. More forests have actually been damaged in Asian countries for the plantation. The producing system of these biodiesel undoubtedly needs fossil fuels 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 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
