The non-renewability, environmental concerns and health dangers connected with the fossil fuels has actually caused exploration of alternative sources of energy to replace the standard ones. A promising innovation, still in its infancy, that might reveal us the way 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 etc can be subjected to oil processing to produce biodiesels. It contains no petroleum but can be mixed with petroleum diesel for usage or might be used in its pure form.

Developed nations specifically United States and European Countries have currently made significant advances in the Biodiesel Technology. Biodiesel have found its usage across markets and verticals and could emerge as a perfect cleaner and cheaper alternative to gas, diesel and nonrenewable fuel sources. India has likewise started checking out the opportunities to produce and use bio-diesel. A number of plants for biodiesel transesterification are already working in the country where vegetable oils are reacted with alcohols (ethanol or methanol usually) to produce bio-diesel.

The main factor for the increasing demand for biodiesels is the fact that biodiesels are eco-friendly and carbon-neutral, hence having no net effect on the climate. Besides, bio-diesel runs in compression engines similar to regular petroleum diesel and hence can be used with little or no engine modifications. Biodiesel do not need any different infrastructure for its storage and can be saved just like the petroleum based fuels.

Considering the growing energy demand in the nation, increasing petroleum rates and the ecological hazards of nonrenewable fuel sources, the Indian Government has actually taken up efforts to establish the Bio Diesel Technology in India and established more oil processing systems. The Government announced its Policy' on 12 September 2008 which intends to fulfill 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 raw materials for oil processing and biodiesel production however in India the maximum potential to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The biggest advantage of utilizing jatropha curcas as a basic material is that this plant can be grown in substantial quantities in wastelands all across India requiring very little water in comparison to other money crops. Once grown, the plant has a helpful lifespan of several decades. The jatropha curcas seeds consist of 40% oil and are thought about to be an exceptional source of bio-diesel. The Government of India has determined 400,000 square kilometres of land ideal for the jatropha curcas cultivation in the nation. India now

A study approximates that even if a mixing initiative of 2% jatropha curcas based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will create around Rs. 5500 crores in the rural economy and aid in decrease of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking actions to motivate the growing of jatropha curcas in India offering complimentary seeds, subsidized loans and other centers. India requires to now reinforce its efforts to make the maximum usage of the Biodiesel Technology. Besides jatropha curcas, the opportunities for drawing out biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil ought to also be explored. It will not only provide an answer to the obstacle of Global Warming but could reduce our dependence on foreign oil and add to our own economy.
