Biofuels is the appealing source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally contains oil specifically jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn and so on by yeast fermentation. Wood products can likewise be converted into Biofuels.

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

Advantages of Biofuels:

Ecological Benefits: The primary expectation of utilizing 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 vehicles. It reduces the green house substantially 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 much better than first generation fuels. It offers 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 considerably if the biofuel production technology spreads worldwide. The biofuels are established locally which instantly enhances the rural development as the innovation depends primarily on manual power. The rapid boost of biofuel all at once increases the production of these oil crops which stimulates the agricultural market. The UK federal government has revealed that it decreases the tax for vehicles which are eco-friendly. Additionally, the toughness of the engine increases while using these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is biodegradable and safer to deal with and less hazardous than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more environments. More have been damaged in Asian countries for the plantation. The producing system of these biodiesel certainly requires fossil fuels which produces more carbon emissions. High preliminary investment is required 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 neighborhoods.

Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking
