Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally contains oil particularly Jatropha, 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 items includes both advantages and downsides.

Advantages of Biofuels:

Ecological Benefits: The main expectation of utilizing 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 good for automobiles. It lowers the green house significantly 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 cost 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 lubricant.

Economical: The biofuel's cost reduces significantly if the biofuel production technology spreads out worldwide. The biofuels are developed in your area which instantly improves the rural advancement as the innovation depends generally on manual power. The fast increase of biofuel simultaneously increases the production of these oil crops which stimulates the agricultural industry. The UK government has actually revealed that it decreases the taxation for cars which are eco-friendly. Additionally, the toughness 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 eco-friendly and more secure to deal with and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will tossed away more habitats. More forests have actually been destroyed in Asian countries for the plantation. The producing mechanism of these biodiesel undoubtedly 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 typically 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; the demand for these crops for biofuels may raise the rate of these food crops. The substantial quantity of water is required for appropriate yield, even for drought resistant Jatropha plants.

Availability: The biofuels are not offered in surplus so the diesel engines which are customized for biodiesel use may face problems. The most vehicles are not equipped for using biofuels in the engines. Some biodiesel can not withstand frost; it gets frozen in the colder areas. It also increases the risk of microbial growth in the engine. Only couple of petrol stations provide this biofuels and it is difficult to carry the biofuels using pipelines.

Carbon emission: Biofuels are minimizes the Jatropha greenhouse compared to other nonrenewable fuel sources. Recently, the European researcher reported that the burning of biodiesel specifically corn and rapeseed produces more nitrous oxide.
