Biofuels is the promising source of energy for future fuel requirements. Biodiesel can be developed from growing plants which naturally consists of oil specifically Jatropha, 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 contains both benefits and drawbacks.

Advantages of Biofuels:

Ecological Benefits: The main 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 renewable and pure fuels so it is excellent for automobiles. It decreases the green house substantially compared to other nonrenewable fuel sources.

First generation biofuels can conserve carbon emissions about 60% compared to nonrenewable fuel sources whereas the second generation biofuels are much better than very first generation fuels. It provides carbon emission savings approximately 80%. Recently, UK Government publication stated that biofuels can decrease emissions by 50-60%. Efficiency of the engine increases by using biodiesel as the lube.

Economical: The biofuel's cost decreases considerably if the biofuel production innovation spreads worldwide. The biofuels are developed in your area which automatically boosts the rural development as the innovation depends generally on manual power. The quick boost of biofuel concurrently increases the production of these oil crops which stimulates the farming market. The UK government has revealed that it lowers the tax for cars which are eco-friendly. Additionally, the durability of the engine increases while utilizing these flammable fuels in engines.

Renewability and Degradable: The biofuels are made from crops which are renewable and it is biodegradable and much safer to deal with and less dangerous than fossil fuels.

Disadvantages of Biofuels:

Environmental Alarm: Adapting more lands for planting crops for biofuel extraction will tossed away more environments. More forests have been ruined in Asian countries for the plantation. The producing system of these biodiesel undoubtedly requires nonrenewable fuel sources which produces more carbon emissions. High initial financial investment is required for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are typically 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 need for these crops for biofuels might raise the cost of these food crops. The huge amount of water is needed for appropriate yield, even for drought resistant Jatropha plants.

Availability: The biofuels are not offered in surplus so the diesel motor which are modified for biodiesel usage may face issues. The most cars are not equipped for using biofuels in the engines. Some biodiesel can not resist frost; it gets frozen in the cooler locations. It also increases the threat of microbial development in the engine. Only couple of fuel stations offer this biofuels and it is difficult to transfer the biofuels utilizing pipelines.

Carbon emission: Biofuels are reduces the Jatropha greenhouse gases emission compared to other nonrenewable fuel sources. Recently, the European researcher reported that the burning of biodiesel especially corn and rapeseed produces more nitrous oxide.
