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, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn etc by yeast fermentation. Wood products can likewise be transformed into Biofuels.

The gotten Biofuels from these items includes both advantages and disadvantages.

Advantages of Biofuels:

Ecological Benefits: The of utilizing 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 is excellent for vehicles. It lowers the green house considerably compared to other nonrenewable fuel sources.

First generation biofuels can conserve carbon emissions about 60% compared to fossil fuels whereas the second generation biofuels are better than very first generation fuels. It provides carbon emission savings approximately 80%. Recently, UK Government publication mentioned that biofuels can minimize 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 innovation spreads out worldwide. The biofuels are developed locally which instantly boosts the rural development as the technology depends generally on manual power. The rapid boost of biofuel simultaneously increases the production of these oil crops which promotes the farming market. The UK government has announced that it reduces the tax for cars which are environment-friendly. Additionally, the sturdiness 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 biodegradable and more secure to manage and less hazardous 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 actually been damaged in Asian countries for the plantation. The producing system of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High initial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those smells are generally unwanted 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
