The non-renewability, ecological issues and health dangers associated with the nonrenewable fuel sources has caused expedition of alternative sources of energy to replace the traditional ones. A promising technology, still in its infancy, that could reveal us the way to the future ahead is Biodiesels. Biodiesels are diesel fuels obtained from grease or animal-fat that might be utilized to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha and so on can be subjected to oil processing to produce biodiesels. It contains no petroleum however can be combined with petroleum diesel for use or might be used in its pure type.

Developed countries particularly United States and European Countries have actually currently made in the Biodiesel Technology. Biodiesel have found its usage throughout markets and verticals and might emerge as an ideal cleaner and cheaper alternative to petrol, diesel and fossil fuels. India has actually also begun exploring the opportunities to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are already functioning in the country where veggie oils are responded with alcohols (ethanol or methanol generally) to produce bio-diesel.

The main factor for the increasing need for biodiesels is the reality that biodiesels are renewable and carbon-neutral, hence having no net effect on the climate. Besides, bio-diesel operates in compression engines similar to regular petroleum diesel and for this reason can be utilized with little or no engine adjustments. Biodiesel do not need any different infrastructure for its storage and can be saved similar to the petroleum based fuels.

Considering the growing energy demand in the country, increasing petroleum prices and the ecological hazards of nonrenewable fuel sources, the Indian Government has taken up initiatives to develop the Bio Diesel Technology in India and set up more oil processing systems. The Government announced its 'National Biofuel Policy' on 12 September 2008 which intends to satisfy 20% of India's diesel demand 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 basic materials for oil processing and biodiesel production however in India the optimal capacity to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha jatropha curcas. The most significant benefit of utilizing jatropha curcas as a basic material is that this plant can be grown in big amounts in wastelands all throughout India requiring 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 consist of 40% oil and are thought about to be an outstanding source of bio-diesel. The Government of India has identified 400,000 square kilometres of land appropriate for the Jatropha cultivation in the nation. India now

A study estimates that even if a blending initiative of 2% jatropha curcas based Biodiesel is achieved in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and aid in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The federal government is taking steps to encourage the cultivation of Jatropha in India providing free seeds, subsidized loans and other centers. India needs to now strengthen its efforts to make the max use of the Biodiesel Technology. Besides Jatropha, the opportunities for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil should also be explored. It will not only provide a response to the obstacle of Global Warming however could reduce our dependence on foreign oil and add to our own economy.
