Biofuels is the promising source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally consists of oil namely 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 items can likewise be converted into Biofuels.

The obtained Biofuels from these items consists of both advantages and disadvantages.

Advantages of Biofuels:

Ecological Benefits: The main 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 good for automobiles. It minimizes the green home substantially compared to other nonrenewable fuel sources.

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

Economical: The biofuel’s cost reduces considerably if the biofuel production technology spreads out worldwide. The biofuels are developed locally which automatically boosts the rural advancement as the innovation depends mainly on manual power. The quick increase of biofuel at the same time increases the production of these oil crops which promotes the agricultural market. The UK government has revealed that it lowers the tax for vehicles which are environmentally friendly. Additionally, the resilience of the engine increases while using these flammable fuels in engines.

and Degradable: The biofuels are made from crops which are sustainable and it is biodegradable and more secure to handle and less hazardous than fossil fuels.

Disadvantages of Biofuels:

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

Odour: Certain biofuel crop produces heavy odor those smells 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
