Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally consists of oil particularly 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 likewise be converted into Biofuels.

The obtained Biofuels from these products consists of both benefits 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 sustainable and pure fuels so it benefits autos. It minimizes the green home considerably compared to other nonrenewable fuel sources.

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

Economical: The biofuel's cost decreases substantially if the biofuel production technology spreads worldwide. The biofuels are developed locally which automatically boosts the rural development as the technology depends primarily on manual power. The fast increase of biofuel simultaneously increases the production of these oil crops which promotes the agricultural industry. The UK government has announced that it minimizes the tax for vehicles which are eco-friendly. Additionally, the resilience of the engine increases while utilizing these flammable fuels in engines.

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

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more habitats. More forests have actually been ruined 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 smells are normally undesirable and biofuels plants can not be setup near the big neighborhoods.

Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking
