ALTERNATIVE SOURCES OF ENERGY
(i) Geothermal Energy This a kind of energy available as heat emitted from within the earth's crust. usually as hot springs, emissions of dry or wet steam. Geothermal energy can be harnessed for power generation, space heating and other thermal applications.
Geothermal energy is most used in Iceland, where it supplies about 15 per cent of the total domestic demand of electricity, mostly for central heating, which, includes domestic heating for the whole of the capital, Reykjavik. Italy, US, Japan, New Zealand, the Philippines, Turkey and former USSR have also shown keen interest in exploiting geothermal power from steam or hot water sources.
Progress in India Preliminary data of resource assessment has been generated for 340 hot springs in the country.
Magneto telluricjnvestigations for assessing the suitability of sites and other studies have been taken up at a few sites through National Geophysical Research Institute (NGRI), Hyderabad. The NGRI has been conducting magnetotelluric (MT) studies in Satluj-Spiti, Beas and Parbati valley in Himachal Pradesh, Badrinath-Tapovan in Uttaranchal and Surajkund in Jharkhand. According to MNES sources, a total of 36 stations have been set up in Badrinath-Tapovan region to collect the data, which is being analysed through computer modeling and quantitative interpretation. Currently, harnessing geothermal energy is not commercially viable.
