The non-renewability, environmental concerns and health risks related to the nonrenewable fuel sources has led to expedition of alternative sources of energy to substitute the conventional ones. An appealing innovation, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels derived from vegetable oil or animal-fat that might be used to run diesel motors. Vegetables oils like sunflower, rape seed, palm oil, soya bean, jatropha curcas etc can be subjected to oil processing to produce biodiesels. It consists of no petroleum but can be mixed with petroleum diesel for usage or could be used in its pure type.

Developed countries specifically United States and European Countries have already made significant advances in the Biodiesel Technology. Biodiesel have found its usage across markets and verticals and might become an ideal cleaner and more affordable alternative to petrol, diesel and fossil fuels. India has also begun exploring the opportunities to produce and utilize bio-diesel. A number of plants for biodiesel transesterification are currently working in the country 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, thus having no net impact on the environment. Besides, bio-diesel operates in compression engines much like normal petroleum diesel and thus can be used with little or no engine modifications. Biodiesel do not require any different infrastructure for its storage and can be saved much like the petroleum based fuels.

Considering the growing energy need in the country, increasing petroleum costs and the environmental threats of nonrenewable fuel sources, the Indian Government has used up efforts to develop the Bio Diesel Technology in India and established more oil processing systems. The Government announced its 'National Biofuel Policy' on 12 September 2008 which intends to fulfill 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 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 advantage of utilizing Jatropha as a basic material is that this plant can be grown in huge amounts in wastelands all throughout India needing extremely little water in comparison to other cash crops. Once grown, the plant has a useful lifespan of a number of years. 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 suitable for the Jatropha growing in the nation. India now

A research study estimates that even if a mixing effort of 2% jatropha curcas based Biodiesel is achieved in 2011-12, India will around Rs. 3000 crores. Besides, it will produce 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 actions to encourage the growing of jatropha curcas in India supplying complimentary seeds, subsidized loans and other facilities. India requires to now enhance its efforts to make the max usage of the Biodiesel Technology. Besides Jatropha, the opportunities for extracting biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil should likewise be checked out. It will not only offer an answer to the obstacle of Global Warming however might decrease our reliance on foreign oil and add to our own economy.
