Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally includes oil specifically 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 transformed into Biofuels.

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

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 eco-friendly and pure fuels so it benefits autos. It reduces the green home significantly compared to other fossil fuels.

First generation biofuels can save carbon emissions about 60% compared to fossil fuels 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 reduce emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel’s cost reduces substantially if the biofuel production technology spreads out worldwide. The biofuels are established locally which immediately enhances the rural development 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 farming industry. The UK federal government has announced that it decreases the taxation for automobiles 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 naturally degradable and safer to manage and less harmful 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 damaged in Asian countries for the plantation. The producing system of these biodiesel certainly needs nonrenewable fuel sources which produces more carbon emissions. High preliminary investment is needed for the biodiesel production.

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