Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally consists of 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 obtained Biofuels from these products 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 benefits cars. It lowers the green home substantially compared to other nonrenewable fuel sources.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the 2nd generation biofuels are better than very first generation fuels. It offers carbon emission savings as much as 80%. Recently, UK Government publication stated that biofuels can lower emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel’s price decreases significantly if the biofuel production technology spreads out worldwide. The biofuels are developed in your area which instantly enhances the rural advancement as the innovation primarily on manual power. The quick increase of biofuel simultaneously increases the production of these oil crops which stimulates the farming industry. The UK federal government has revealed that it reduces the tax for vehicles which are eco-friendly. Additionally, the durability of the engine increases while using these combustible fuels in engines.

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

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more habitats. More forests have been damaged in Asian nations for the plantation. The producing mechanism of these biodiesel certainly requires 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 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
