The non-renewability, ecological concerns and health risks associated with the nonrenewable fuel sources has actually resulted in expedition of alternative sources of energy to substitute the traditional ones. An appealing technology, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels stemmed from grease or animal-fat that could be used 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 contains no petroleum but can be combined with petroleum diesel for usage or could be used in its pure type.

Developed countries particularly United States and European Countries have already made considerable advances in the Biodiesel Technology. Biodiesel have actually found its usage throughout markets and verticals and might become a perfect cleaner and cheaper option to fuel, diesel and fossil fuels. India has likewise begun exploring the opportunities to produce and utilize bio-diesel. A number of plants for biodiesel transesterification are already working in the nation where veggie oils are reacted with alcohols (ethanol or methanol generally) to produce bio-diesel.

The main reason for the increasing demand for biodiesels is the fact that biodiesels are renewable and carbon-neutral, thus having no net effect on the environment. Besides, bio-diesel runs in compression engines much like typical petroleum diesel and thus can be utilized with little or no engine modifications. Biodiesel do not need any separate infrastructure for its storage and can be stored simply like the petroleum based fuels.

Considering the growing energy need in the country, increasing petroleum prices and the environmental risks of nonrenewable fuel sources, the Indian Government has taken up initiatives to develop the Bio Diesel Technology in India and established more oil processing systems. The Government revealed its 'National Biofuel Policy' on 12 September 2008 which aims to fulfill 20% of India's diesel need with bio-fuels in the coming years.

Globally, 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 optimal capacity to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest advantage of utilizing Jatropha as a basic material is that this plant can be grown in substantial quantities in wastelands all across 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 thought about to be an outstanding source of bio-diesel. The Government of India has identified 400,000 square kilometres of land ideal for the Jatropha growing in the country. India now

A study approximates that even if a blending initiative of 2% Jatropha based Biodiesel is achieved in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will create 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 encourage the growing of jatropha curcas in India offering complimentary seeds, subsidized loans and other facilities. India requires to now strengthen its efforts to make the max usage of the Biodiesel Technology. Besides Jatropha, the avenues for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil need to also be checked out. It will not only offer a response to the obstacle of Global Warming however might decrease our reliance on foreign oil and contribute to our own economy.
