Biofuels is the promising source of energy for future fuel needs. Biodiesel can be established 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 etc by yeast fermentation. Wood products can also be converted into Biofuels.

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

Advantages of Biofuels:

Ecological Benefits: The main 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 benefits cars. It lowers the green home significantly compared to other fossil fuels.

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

Economical: The biofuel's price reduces substantially if the biofuel production innovation spreads worldwide. The biofuels are developed in your area which automatically improves the rural development as the technology depends mainly on manual power. The rapid boost of biofuel all at once increases the production of these oil crops which promotes the farming industry. The UK government has actually announced that it decreases the tax for vehicles 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 sustainable and it is eco-friendly and more secure to manage and less harmful than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will threw away more habitats. More forests have actually been ruined in Asian countries for the plantation. The producing system of these biodiesel indeed requires fossil fuels 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 large communities.

Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking; the demand for these crops for biofuels may raise the price of these food crops. The huge quantity of water is needed for appropriate yield, even for drought resistant jatropha curcas plants.

Availability: The biofuels are not offered in surplus so the diesel motor which are customized for biodiesel usage might face issues. The most vehicles are not equipped for using biofuels in the engines. Some biodiesel can not withstand frost; it gets frozen in the chillier locations. It also increases the threat of microbial growth in the engine. Only few fuel stations use this biofuels and it is impossible to carry the biofuels using pipelines.

Carbon emission: Biofuels are lowers the jatropha curcas greenhouse gases emission compared to other nonrenewable fuel sources. Recently, the European researcher reported that the burning of biodiesel specifically corn and rapeseed produces more laughing gas.
