The non-renewability, ecological concerns and health risks related to the nonrenewable fuel sources has led to expedition of of energy to substitute the standard ones. An appealing innovation, still in its infancy, that might reveal us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels stemmed from grease or animal-fat that might be utilized to run diesel motors. 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 consists of no petroleum but can be combined with petroleum diesel for usage or could be used in its pure kind.

Developed countries specifically United States and European Countries have already made significant advances in the Biodiesel Technology. Biodiesel have discovered its usage throughout markets and verticals and could become a perfect cleaner and more affordable option to gas, diesel and fossil fuels. India has also begun checking out the chances to produce and use bio-diesel. A number of plants for biodiesel transesterification are already functioning in the country where vegetable oils are reacted with alcohols (ethanol or methanol typically) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the truth that biodiesels are sustainable and carbon-neutral, thus having no net influence on the climate. Besides, bio-diesel operates in compression engines similar to regular petroleum diesel and thus can be used with little or no engine adjustments. Biodiesel do not require any different facilities for its storage and can be stored much like the petroleum based fuels.

Considering the growing energy need in the country, rising petroleum prices and the ecological risks of fossil fuels, the Indian Government has actually used up efforts 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 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 used as the pre-dominant basic materials for oil processing and biodiesel production but in India the maximum potential to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The biggest advantage of using jatropha curcas as a basic material is that this plant can be grown in substantial quantities in wastelands all throughout India needing very little water in comparison to other money crops. Once grown, the plant has a useful life expectancy of a number of years. The Jatropha seeds contain 40% oil and are considered to be an outstanding source of bio-diesel. The Government of India has actually determined 400,000 square kilometres of land appropriate for the Jatropha cultivation in the country. India now

A study approximates that even if a mixing initiative of 2% jatropha curcas based Biodiesel is accomplished in 2011-12, India will save around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and assistance in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking actions to motivate the growing of Jatropha in India supplying totally free seeds, subsidized loans and other facilities. India needs to now strengthen its efforts to make the max usage of the Biodiesel Technology. Besides Jatropha, the avenues for extracting biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil need to also be explored. It will not only offer a response to the difficulty of Global Warming however could reduce our dependence on foreign oil and contribute to our own economy.
