The non-renewability, environmental issues and health hazards related to the nonrenewable fuel sources has actually resulted in expedition of alternative sources of energy to replace the conventional ones. An appealing innovation, still in its infancy, that could reveal us the way to the future ahead is Biodiesels. Biodiesels are diesel fuels derived from veggie oil or animal-fat that might be utilized to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha 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 might be used in its pure form.

Developed nations particularly United States and European Countries have currently made considerable advances in the Biodiesel Technology. Biodiesel have actually discovered its usage throughout industries and verticals and could become a perfect cleaner and less expensive alternative to gas, diesel and nonrenewable fuel sources. India has likewise started exploring the chances to produce and utilize bio-diesel. A number of plants for biodiesel transesterification are already operating in the country where veggie oils are reacted with alcohols (ethanol or methanol generally) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the truth that biodiesels are renewable and carbon-neutral, therefore having no net effect on the environment. Besides, bio-diesel operates in compression engines just like normal petroleum diesel and hence can be used with little or no engine modifications. Biodiesel do not need any separate facilities for its storage and can be kept similar to the petroleum based fuels.

Considering the growing energy need in the nation, increasing and the ecological dangers of nonrenewable fuel sources, the Indian Government has used up efforts to develop the Bio Diesel Technology in India and set up more oil processing systems. 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 raw materials for oil processing and biodiesel production however in India the maximum capacity to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The biggest benefit of utilizing jatropha curcas as a basic material is that this plant can be grown in substantial quantities in wastelands all throughout India requiring really little water in contrast to other money crops. Once grown, the plant has a useful lifespan of a number of years. The Jatropha seeds include 40% oil and are considered to be an outstanding source of bio-diesel. The Government of India has actually identified 400,000 square kilometres of land suitable for the jatropha curcas growing in the country. India now

A study approximates that even if a mixing effort of 2% Jatropha based Biodiesel is achieved in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will produce around Rs. 5500 crores in the rural economy and help in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking steps to encourage the cultivation of jatropha curcas in India supplying complimentary seeds, subsidized loans and other centers. India needs to now strengthen its efforts to make the maximum use of the Biodiesel Technology. Besides Jatropha, the avenues for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil should also be checked out. It will not only provide an answer to the difficulty of Global Warming however might reduce our reliance on foreign oil and contribute to our own economy.
