The sun, wind, water & bio-mass are either Perennial or renewable sources of energy. Any or more of these sources are available in almost each part of the country. These available sources can be utilized effectively for useful purpose through technological means. Bio-mass is renewable energy resource. This energy potential is solar in origin & is a convenient form of chemical energy obtained by the conversion of solar energy in plants & trees, through the process of photosynthesis. Worldwide photosynthetic activity is estimated to store about 17 times energy which is annually consumed by all nations in the world. It is locally available energy resource & is considered a major cooking fuel in the rural areas.
[...] 10) OCEAN ENERGY The ocean which covers about 71% of earth's surface acts as a natural collector of solar energy. Thus ocean has and enormous potential to supply energy in many different ways. The various forms in which this energy could be harnessed through technologically viable means are Ocean Thermal Energy Conversion (OTEC) Wave/Tidal Energy. Ocean Thermal Energy conversion (OTEC) system is an important energy resource for the country like India having a long coast of tropical waters. This pollution free energy source is a continuous one and similar to that obtained from thermal or nuclear power plant. [...]
[...] SOLAR ENERGY Sun is abundant source of renewable energy. The power from the sun intercepted by the earth is approximately 1.8 x 1011 MW. This source of renewable energy offers the best opportunities for widest applications in both solar thermal and photovoltaic systems. The daily average solar energy incident on India is 5-6 kwh/m2, which works out to almost 20000 times. Times the current consumption of electrical energy in the country. In many applications this has to be collected over large investment. [...]
[...] MICRO-MINI HYDRO ENERGY Hydropower at small level too was extensively in use in rural India in the form of flows mills in the present scenario. The use of hydropower as massive projects (i. E. big dams) is not thought to be appropriate in social or environmental forms. Besides. The availability of large scale hydro sites is also limited. Then small hydropower development promises a more appropriate level for the electrification of rural off grid villages in India. Mini hydropower. Typically grid connected schemes of up to a far MW in capacity can prove to be valuable and cost effective tools of electricity generation. [...]
