Biofuels is the appealing source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally includes 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 gotten Biofuels from these products includes both advantages and drawbacks.

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 resources, and it is eco-friendly and pure fuels so it benefits automobiles. It lowers the green house considerably compared to other fossil fuels.

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

Economical: The biofuel's rate decreases significantly if the biofuel production technology spreads out worldwide. The biofuels are established in your area which automatically improves the rural development as the technology depends primarily on manual power. The quick increase of biofuel concurrently increases the production of these oil crops which promotes the agricultural industry. The UK government has announced that it reduces the tax 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 sustainable and it is eco-friendly and safer to manage and less dangerous than .

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more environments. More forests have been ruined in Asian nations for the plantation. The producing mechanism of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High initial financial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell those smells are generally undesirable and biofuels plants can not be setup near the big neighborhoods.

Food and water Requirements: Some biofuel crops such as corn oil, palm oil are edible for cooking; the need for these crops for biofuels might raise the rate of these food crops. The huge amount of water is needed for appropriate yield, even for dry spell resistant jatropha curcas plants.

Availability: The biofuels are not available in surplus so the diesel motor which are modified for biodiesel use may deal with issues. The most autos are not geared up for using biofuels in the engines. Some biodiesel can not withstand frost; it gets frozen in the cooler areas. It also increases the danger of microbial growth in the engine. Only couple of fuel stations provide this biofuels and it is impossible to carry the biofuels using pipelines.

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