Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally includes oil specifically jatropha curcas, 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 also be transformed into Biofuels.

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

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 deposits, and it is eco-friendly and pure fuels so it is great for vehicles. It decreases the green house significantly compared to other nonrenewable fuel sources.

First generation biofuels can save carbon emissions about 60% compared to fossil fuels whereas the 2nd generation biofuels are better than very first generation fuels. It provides carbon emission cost savings as much as 80%. Recently, UK Government publication mentioned that biofuels can decrease emissions by 50-60%. Efficiency of the engine increases by utilizing biodiesel as the lubricant.

Economical: The biofuel’s rate reduces substantially if the biofuel production technology spreads out worldwide. The biofuels are established locally which automatically improves the rural advancement as the technology depends primarily on manual power. The quick increase of biofuel all at once increases the production of these oil crops which promotes the farming industry. The UK government has revealed that it reduces the taxation for lorries which are environment-friendly. Additionally, the toughness of the engine increases while using these combustible fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are sustainable and it is naturally degradable and much safer to handle and less dangerous 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 been damaged in Asian nations for the plantation. The producing system of these biodiesel certainly requires fossil fuels which produces more carbon emissions. High initial financial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those odours 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
