Biofuels is the promising source of energy for future fuel needs. 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 and so on by yeast fermentation. Wood items can also be converted into Biofuels.

The acquired Biofuels from these items includes 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 deposits, and it is renewable and pure fuels so it is excellent for autos. It lowers the green house considerably compared to other fossil fuels.

First generation biofuels can save carbon emissions about 60% compared to nonrenewable fuel sources whereas the second generation biofuels are better than very first generation fuels. It offers carbon emission savings up to 80%. Recently, UK Government publication mentioned that biofuels can lower emissions by 50-60%. Efficiency of the engine increases by using 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 automatically boosts the rural advancement as the technology depends primarily on manual power. The quick increase of biofuel at the same time increases the production of these oil crops which stimulates the farming market. The UK government has actually announced that it decreases the taxation for vehicles which are eco-friendly. Additionally, the durability of the engine increases while utilizing these flammable fuels in engines.

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

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more environments. More forests have been damaged in Asian countries for the plantation. The of these biodiesel certainly needs nonrenewable fuel sources which produces more carbon emissions. High preliminary financial investment is needed for the biodiesel production.

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