Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed 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 gotten Biofuels from these products includes both and downsides.

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 great for vehicles. It minimizes the green house considerably compared to other fossil fuels.

First generation biofuels can save carbon emissions about 60% compared to nonrenewable fuel sources whereas the 2nd generation biofuels are much better than first generation fuels. It offers carbon emission cost savings approximately 80%. Recently, UK Government publication specified 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 out worldwide. The biofuels are established in your area which instantly enhances the rural development as the technology depends generally on manual power. The rapid increase of biofuel simultaneously increases the production of these oil crops which stimulates the farming market. The UK federal government has revealed that it decreases the taxation for cars which are environmentally friendly. Additionally, the sturdiness 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 dangerous than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more habitats. More forests have actually been destroyed in Asian countries for the plantation. The producing system of these biodiesel undoubtedly 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 typically unwanted 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
