The non-renewability, environmental concerns and health hazards related to the fossil fuels has actually led to expedition of alternative sources of energy to substitute the traditional ones. A promising technology, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels originated from veggie oil or animal-fat that could be utilized to run diesel motors. like sunflower, rape seed, palm oil, soya bean, jatropha curcas and so on can be subjected to oil processing to produce biodiesels. It includes no petroleum however can be blended with petroleum diesel for use or might be utilized in its pure kind.

Developed countries particularly United States and European Countries have already made significant advances in the Biodiesel Technology. Biodiesel have found its usage throughout markets and verticals and could emerge as a perfect cleaner and cheaper option to petrol, diesel and nonrenewable fuel sources. India has likewise begun exploring the opportunities to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are currently working in the nation where vegetable oils are reacted with alcohols (ethanol or methanol typically) to produce bio-diesel.

The main factor for the increasing need for biodiesels is the truth that biodiesels are eco-friendly and carbon-neutral, hence having no net effect on the environment. Besides, bio-diesel operates in compression engines much like typical petroleum diesel and thus can be used with little or no engine adjustments. Biodiesel do not need any separate facilities for its storage and can be kept much like the petroleum based fuels.

Considering the growing energy need in the nation, increasing petroleum rates and the environmental hazards of nonrenewable fuel sources, the Indian Government has actually taken up efforts to develop the Bio Diesel Technology in India and established more oil processing systems. The Government announced its 'National Biofuel Policy' on 12 September 2008 which aims to meet 20% of India's diesel demand with bio-fuels in the coming years.

Globally, edible vegetable oils like sunflower, soya bean, rape seed, palm oil are utilized as the pre-dominant basic materials for oil processing and biodiesel production however in India the maximum potential to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest benefit of using Jatropha as a raw product is that this plant can be grown in substantial quantities in wastelands all across India needing extremely little water in comparison to other money crops. Once grown, the plant has a beneficial life expectancy of a number of decades. The jatropha curcas seeds contain 40% oil and are considered to be an exceptional source of bio-diesel. The Government of India has recognized 400,000 square kilometres of land appropriate for the jatropha curcas cultivation in the country. India now

A study approximates that even if a blending initiative of 2% jatropha curcas based Biodiesel is attained in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and help in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking steps to motivate the growing of Jatropha in India providing free seeds, subsidized loans and other facilities. India requires to now enhance its efforts to make the maximum usage of the Biodiesel Technology. Besides Jatropha, the avenues for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil must also be checked out. It will not just provide a response to the challenge of Global Warming however might decrease our dependence on foreign oil and add to our own economy.
