Biofuels is the promising source of energy for future fuel needs. Biodiesel can be developed from growing plants which naturally contains oil specifically jatropha curcas, palm oil, Soybean and algae. Bioethanol can be drawn out from sugar crops like sugarcane, sugar beet, maize, corn and so on by yeast fermentation. Wood products can also be transformed into Biofuels.

The obtained Biofuels from these items consists of both benefits and downsides.

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 resources, and it is sustainable and pure fuels so it is great for autos. It reduces the green home significantly compared to other fossil fuels.

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

Economical: The price reduces substantially if the biofuel production technology spreads out worldwide. The biofuels are developed locally which instantly boosts the rural development as the technology depends primarily on manual power. The rapid increase of biofuel concurrently increases the production of these oil crops which stimulates the farming market. The UK government has actually revealed that it decreases the taxation for automobiles which are eco-friendly. Additionally, the resilience of the engine increases while using 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 manage 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 destroyed in Asian countries for the plantation. The producing mechanism of these biodiesel indeed requires fossil fuels which produces more carbon emissions. High preliminary financial investment is needed for the biodiesel production.

Odour: Certain biofuel crop produces heavy odor those smells are normally 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
