Correct Answer: A
Solution :
[a] In simple words 'geo' means earth and 'Thermal' means heat. Thus geothermal energy is that heat energy obtained from hot rocks present inside the earth and this can be used as a source of energy to produce electricity. Among the various new and renewable energy options, geothermal energy is recognised as the cleanest, without smoke or environmental hazards. Some features of Geothermal energy are Geothermal energy is almost pollution-free. Geothermal plants can operate round the clock, unlike those based on solar and tidal energy. The cost of a geothermal plant is high as compared to a coal-based plant, but operating costs are lower. The source of energy is free and renewable. In India, there are about 400 hot springs that can be tapped for geothermal energy. Ladakh, Gujarat and Madhya Pradesh have good geothermal energy potential. It is estimated that 10, 000 MW of electricity can be generated from geothermal plants in India. As part of promoting non-conventional energy, the GOI is setting up the its first Geothermal Power Project in Ladakh.
