Biofuels is the appealing source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally contains oil namely jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out 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 contains both benefits and drawbacks.

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 resources, and it is renewable and pure fuels so it is excellent for automobiles. It reduces the green home significantly compared to other nonrenewable fuel sources.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the second generation biofuels are better than first generation fuels. It provides carbon emission cost savings up to 80%. Recently, UK Government publication stated that biofuels can minimize 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 technology spreads out worldwide. The biofuels are established locally which instantly enhances the rural advancement as the technology depends generally on manual power. The quick boost of biofuel at the same time increases the production of these oil crops which stimulates the farming market. The UK government has revealed that it reduces the tax for automobiles which are eco-friendly. Additionally, the durability of the engine increases while utilizing these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are eco-friendly and it is biodegradable and more secure to handle 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 been ruined in for the plantation. The producing mechanism of these biodiesel undoubtedly requires fossil fuels which produces more carbon emissions. High preliminary investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those odours are typically 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
