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

The acquired Biofuels from these products consists of both benefits and downsides.

Advantages of Biofuels:

Ecological Benefits: The primary expectation of using the biofuel is to be carbon neutral, less of CO and Sulfur, as it is made from natural deposits, and it is eco-friendly and pure fuels so it is great for autos. It reduces the green house substantially 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 cost savings approximately 80%. Recently, UK Government publication stated that biofuels can reduce emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's rate decreases considerably if the biofuel production innovation spreads out worldwide. The biofuels are established in your area which instantly improves the rural advancement as the technology depends mainly on manual power. The fast increase of biofuel all at once increases the production of these oil crops which stimulates the agricultural market. The UK government has revealed that it reduces the taxation for vehicles which are eco-friendly. Additionally, the sturdiness of the engine increases while utilizing these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are renewable and it is biodegradable and much safer to deal with and less hazardous than fossil fuels.

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 certainly needs fossil fuels which produces more carbon emissions. High preliminary financial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those smells are normally undesirable 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
