Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be established from growing plants which naturally contains 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 products can also be transformed into Biofuels.

The acquired Biofuels from these products consists of both benefits 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 sustainable and pure fuels so it benefits automobiles. It decreases the green house significantly 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 very first generation fuels. It provides carbon emission savings up to 80%. Recently, UK Government publication mentioned that biofuels can reduce emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's cost decreases considerably if the biofuel production technology spreads out worldwide. The biofuels are developed in your area which automatically enhances the rural development as the technology depends primarily on manual power. The rapid boost of biofuel simultaneously increases the production of these oil crops which stimulates the agricultural industry. The UK federal government has revealed that it minimizes the taxation for cars which are environmentally friendly. Additionally, the resilience of the engine increases while using these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are renewable and it is biodegradable and safer to manage and less harmful than fossil fuels.

Disadvantages of Biofuels:

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

Odour: Certain biofuel crop produces heavy smell those odours are usually unfavorable and biofuels plants can not be setup near the large neighborhoods.

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