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

The gotten Biofuels from these items contains both benefits 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 good for automobiles. It reduces the green home 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 offers carbon emission cost savings approximately 80%. Recently, UK Government publication mentioned that biofuels can lower emissions by 50-60%. of the engine increases by utilizing biodiesel as the lube.

Economical: The biofuel's price reduces considerably if the biofuel production technology spreads worldwide. The biofuels are established in your area which immediately enhances the rural advancement as the technology depends generally on manual power. The quick increase of biofuel simultaneously increases the production of these oil crops which stimulates the agricultural market. The UK government has revealed that it decreases the tax for automobiles which are environment-friendly. Additionally, the toughness 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 naturally degradable and safer to handle and less hazardous than nonrenewable fuel sources.

Disadvantages of Biofuels:

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

Odour: Certain biofuel crop produces heavy odor those smells 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; the demand for these crops for biofuels may raise the price of these food crops. The big quantity of water is required for correct yield, even for drought resistant jatropha curcas plants.

Availability: The biofuels are not available in surplus so the diesel engines which are customized for biodiesel usage might face issues. The most automobiles are not equipped for using biofuels in the engines. Some biodiesel can not withstand frost; it gets frozen in the cooler locations. It also increases the danger of microbial growth in the engine. Only couple of gas stations use this biofuels and it is impossible to transfer the biofuels utilizing pipelines.

Carbon emission: Biofuels are reduces 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 nitrous oxide.
