The non-renewability, ecological issues and health risks associated with the sources has caused exploration of alternative sources of energy to substitute the conventional ones. An appealing innovation, still in its infancy, that might show us the way to the future ahead is Biodiesels. Biodiesels are diesel fuels obtained from vegetable oil or animal-fat that might 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 includes no petroleum however can be combined with petroleum diesel for use or might be utilized in its pure type.

Developed countries specifically United States and European Countries have currently made substantial advances in the Biodiesel Technology. Biodiesel have actually found its usage across industries and verticals and could become an ideal cleaner and cheaper option to fuel, diesel and nonrenewable fuel sources. India has likewise started checking out the chances to produce and utilize bio-diesel. A variety 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 primary factor for the increasing need for biodiesels is the reality that biodiesels are sustainable and carbon-neutral, therefore having no net influence on the climate. Besides, bio-diesel runs in compression engines much like typical petroleum diesel and for this reason can be utilized with little or no engine modifications. Biodiesel do not need any different infrastructure for its storage and can be stored similar to the petroleum based fuels.

Considering the growing energy need in the country, rising petroleum rates and the ecological risks of nonrenewable fuel sources, the Indian Government has used up initiatives to develop the Bio Diesel Technology in India and established more oil processing units. The Government announced its 'National Biofuel Policy' on 12 September 2008 which aims to meet 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 basic materials for oil processing and biodiesel production however in India the optimal potential to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest benefit of utilizing Jatropha as a raw product is that this plant can be grown in substantial amounts in wastelands all throughout India requiring really little water in contrast to other cash crops. Once grown, the plant has a useful lifespan of several decades. The jatropha curcas seeds contain 40% oil and are thought about to be an exceptional source of bio-diesel. The Government of India has recognized 400,000 square kilometres of land appropriate for the jatropha curcas growing in the nation. India now

A research 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 aid in reduction 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 providing complimentary seeds, subsidized loans and other centers. India requires to now enhance its efforts to make the maximum usage of the Biodiesel Technology. Besides jatropha curcas, the avenues for drawing out biodiesel from veggie 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 but could reduce our reliance on foreign oil and contribute to our own economy.
