The non-renewability, environmental issues and health hazards associated with the nonrenewable fuel sources has actually resulted in exploration of alternative sources of energy to substitute the standard ones. A promising technology, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels originated from vegetable oil or animal-fat that might be utilized to run diesel motors. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha and so on can be subjected to oil processing to produce biodiesels. It consists of no petroleum but can be blended with petroleum diesel for usage or might be utilized in its pure kind.

Developed nations especially United States and European Countries have currently made substantial advances in the Biodiesel Technology. Biodiesel have actually found its use throughout markets and verticals and could become an ideal cleaner and cheaper option to gas, diesel and nonrenewable fuel sources. India has likewise started checking out the opportunities to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are already functioning in the nation where vegetable oils are responded with alcohols (ethanol or methanol normally) to produce bio-diesel.

The primary reason for the increasing demand for biodiesels is the fact that biodiesels are sustainable and carbon-neutral, therefore having no net impact on the environment. Besides, bio-diesel operates in compression engines similar to typical petroleum diesel and hence can be utilized with little or no . Biodiesel do not require any separate infrastructure for its storage and can be kept much like the petroleum based fuels.

Considering the growing energy demand in the nation, rising petroleum costs and the environmental risks of nonrenewable fuel sources, the Indian Government has taken up initiatives to establish 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 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 but 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 greatest benefit of using jatropha curcas as a basic material is that this plant can be grown in huge amounts in wastelands all across India requiring really little water in comparison to other money crops. Once grown, the plant has a beneficial life expectancy of several years. The jatropha curcas seeds consist of 40% oil and are considered to be an excellent source of bio-diesel. The Government of India has recognized 400,000 square kilometres of land suitable for the jatropha curcas growing in the nation. India now

A research study estimates that even if a mixing effort of 2% Jatropha based Biodiesel is attained in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and help in decrease 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 in India offering free seeds, subsidized loans and other centers. India needs to now enhance its efforts to make the fullest usage of the Biodiesel Technology. Besides jatropha curcas, 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 a response to the difficulty of Global Warming however might decrease our reliance on foreign oil and contribute to our own economy.
