Biofuels is the promising source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally includes oil namely jatropha curcas, 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 likewise be converted into Biofuels.

The gotten Biofuels from these items includes both advantages and disadvantages.

Advantages of Biofuels:

Ecological Benefits: The primary 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 eco-friendly and pure fuels so it is excellent for cars. It lowers the green home substantially compared to other fossil fuels.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the second 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 utilizing biodiesel as the lubricant.

Economical: The biofuel's price reduces substantially if the biofuel production innovation spreads out worldwide. The biofuels are established locally which instantly enhances the rural development as the technology depends generally on manual power. The quick increase of biofuel all at once increases the production of these oil crops which stimulates the agricultural market. The UK federal government has actually announced that it lowers the tax for lorries which are eco-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 handle and less hazardous than nonrenewable fuel sources.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will discarded more habitats. More forests have been damaged in Asian countries for the plantation. The producing system of these biodiesel certainly requires fossil fuels which produces more carbon emissions. High preliminary investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy smell 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 need for these crops for biofuels might raise the cost of these food crops. The substantial quantity of water is required for correct yield, even for dry spell resistant Jatropha plants.

Availability: The biofuels are not readily available in surplus so the diesel engines which are customized for biodiesel use may face issues. The most automobiles are not equipped for using biofuels in the engines. Some biodiesel can not resist frost; it gets frozen in the cooler areas. It likewise increases the risk of microbial development in the engine. Only couple of fuel stations offer this biofuels and it is impossible to transfer the biofuels utilizing pipelines.

Carbon emission: Biofuels are lowers the Jatropha greenhouse gases emission compared to other fossil fuels. Recently, the European scientist reported that the burning of biodiesel particularly corn and rapeseed produces more nitrous oxide.
