The non-renewability, ecological issues and health risks connected with the fossil fuels has caused expedition of alternative sources of energy to replace the standard ones. An appealing innovation, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are stemmed from grease or animal-fat that could be utilized to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, jatropha curcas and so on can be subjected to oil processing to produce biodiesels. It contains no petroleum but can be mixed with petroleum diesel for usage or could be used in its pure kind.

Developed countries specifically United States and European Countries have currently made considerable advances in the Biodiesel Technology. Biodiesel have found its usage across markets and verticals and might become an ideal cleaner and less expensive option to fuel, diesel and nonrenewable fuel sources. India has also started checking out the opportunities to produce and use bio-diesel. A variety of plants for biodiesel transesterification are currently working in the country where veggie oils are reacted with alcohols (ethanol or methanol typically) to produce bio-diesel.

The primary factor for the increasing demand for biodiesels is the truth that biodiesels are renewable and carbon-neutral, hence having no net effect on the climate. Besides, bio-diesel runs in compression engines similar to typical petroleum diesel and for this reason can be used with little or no engine adjustments. Biodiesel do not need any different facilities for its storage and can be stored simply like the petroleum based fuels.

Considering the growing energy demand in the country, rising petroleum rates and the environmental dangers of nonrenewable fuel sources, the Indian Government has used up initiatives to develop the Bio Diesel Technology in India and set up more oil processing units. The Government announced its 'National Biofuel Policy' on 12 September 2008 which aims 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 utilized as the pre-dominant basic materials for oil processing and biodiesel production however in India the maximum capacity to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The biggest benefit of utilizing jatropha curcas as a raw material is that this plant can be grown in big amounts in wastelands all throughout India requiring extremely little water in contrast to other cash crops. Once grown, the plant has a beneficial life expectancy of a number of years. The Jatropha seeds contain 40% oil and are considered to be an excellent source of bio-diesel. The Government of India has determined 400,000 square kilometres of land suitable for the jatropha curcas cultivation in the country. India now

A research study approximates that even if a blending effort of 2% Jatropha based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will produce 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 actions to motivate the cultivation of Jatropha in India offering free seeds, subsidized loans and other centers. India requires to now reinforce its efforts to make the fullest use of the Biodiesel Technology. Besides jatropha curcas, the avenues for drawing out biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil need to also be checked out. It will not just provide a response to the obstacle of Global Warming but might reduce our reliance on foreign oil and add to our own economy.
