The non-renewability, environmental issues and health threats connected with the nonrenewable fuel sources has resulted in expedition of alternative sources of energy to substitute the traditional ones. A promising innovation, 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 used to run diesel engines. oils like sunflower, rape seed, palm oil, soya bean, jatropha curcas etc can be subjected to oil processing to produce biodiesels. It includes no petroleum but can be combined with petroleum diesel for usage or could be used in its pure type.

Developed countries especially United States and European Countries have already made substantial advances in the Biodiesel Technology. Biodiesel have found its usage throughout industries and verticals and might become an ideal cleaner and more affordable option to gas, diesel and nonrenewable fuel sources. India has also begun checking out the chances to produce and use bio-diesel. A number of plants for biodiesel transesterification are currently working in the nation where veggie oils are responded with alcohols (ethanol or methanol typically) to produce bio-diesel.

The main factor for the increasing demand for biodiesels is the fact that biodiesels are renewable and carbon-neutral, hence having no net influence on the climate. Besides, bio-diesel runs in compression engines simply like normal petroleum diesel and hence can be used with little or no engine adjustments. Biodiesel do not need any separate infrastructure for its storage and can be stored much like the petroleum based fuels.

Considering the growing energy need in the nation, rising petroleum rates and the ecological dangers of fossil fuels, the Indian Government has taken up initiatives to develop the Bio Diesel Technology in India and set up more oil processing units. The Government revealed its 'National Biofuel Policy' on 12 September 2008 which intends to satisfy 20% of India's diesel need with bio-fuels in the coming years.

Globally, edible veggie oils like sunflower, soya bean, rape seed, palm oil are used as the pre-dominant raw products for oil processing and biodiesel production however in India the optimal capacity to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest advantage of utilizing jatropha curcas as a raw product is that this plant can be grown in big amounts in wastelands all across India requiring extremely little water in contrast to other money crops. Once grown, the plant has a useful life expectancy of a number of years. The Jatropha seeds consist of 40% oil and are considered to be an excellent source of bio-diesel. The Government of India has actually identified 400,000 square kilometres of land appropriate for the jatropha curcas growing in the country. India now

A study estimates 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 produce around Rs. 5500 crores in the rural economy and help in decrease of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The federal government is taking steps to motivate the growing of jatropha curcas in India supplying totally free seeds, subsidized loans and other centers. India requires to now enhance its efforts to make the fullest use of the Biodiesel Technology. Besides jatropha curcas, the opportunities for extracting biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil ought to also be explored. It will not just provide an answer to the difficulty of Global Warming but could decrease our dependence on foreign oil and contribute to our own economy.
