I am Rupa.I want a ppt on non conventional sources.

These links have some ppts:

non conventional sources


Non-conventional sources of energy in India comprise those energy sources that are natural, inexhaustible as well as renewable. Like for instance, solar energy, tidal energy and wind energy. Interestingly, wind and running water were in use as sources of energy long before the conventional sources of energy like coal, mineral oil and natural gas came to be used widely. Initially, windmills were used for grinding grains as well as for pumping water. Wind and running water were also used for navigation. In present times, some of the major and extensively used non-conventional sources energy includes wind, tides, solar geo-thermal heat, biomass including farm and animal waste as well as human excreta. Like for instance, sewage from large cities can be used for generating biogas. All these sources are renewable or inexhaustible. They are inexpensive in nature.

Some of the Non-Conventional Sources of Energy in India are as follows -
Wind Energy: This type of non-conventional energy can be used for pumping water, a prime need in irrigating farms in the countryside. Also, it can be used for generating electricity. The states of Gujarat, Tamil Nadu, Maharashtra and Orissa are better places in regard to this energy. Areas with constant and high speed winds are suitable for the purpose. Besides windmills, there are also wind farms.

Tidal Energy: This is another unlimited and inexhaustible source of energy. The Gulfs of Kutch is preferably suited to build up electricity from the energy produced by high and lofty tides entering into slender creeks.

Solar Energy: The most copious and inexhaustible source of energy is the sun. It is a universal source and has huge potential and thus solar energy is one of the most prominent non-conventional energy used in the country. A notable achievement has been the solar cookers that are very cost effective. They help in cooking food almost without any-cost. Further, several small and medium size solar power stations are being planned for rural areas of the country. Some of the successful applications of the solar energy so far have been for cooking, water heating, water desalination, space heating, and crop drying. It is also predicted that it is going to be the energy of future when fossil fuels, namely coal and oil, would be totally exhausted.

Measures to Produce Non-Conventional Source Of Energy
Thermal Energy: India is not rich in thermal energy source. However, efforts are on for the complete utilisation of natural energy of the hot springs at Manikaran in Himachal Pradesh. Energy so formed can be used for running cold storage plants.

Biomass: Several efforts are being made in the country for making proper use of biomass in an effective and actually in a more scientific manner. The two main components of the biomass programme are production and utilisation of biomass.
