Geothermal energy is derived from the earth’s heat. This underground reservoir of steam and hot water is tapped to generate electricity.
Geothermal power stations do not create any pollution and can be used to produce electricity 24 hours a day. Therefore, it is a clean, inexpensive and renewable source of energy. If harnessed efficiently, it leads to no harmful by-products. The power plants are usually small and therefore have less effect on the surroundings. The cost of building a geothermal plant is comparatively lesser than an oil, gas or nuclear plant.
Some of the potential applications of geothermal energy that have not been utilised to the fullest are:
What’s happening in the world? In February last year, Kenya initiated the biggest-ever geothermal power plant, using the large magnitude of heat below the Earth’s surface to power turbines producing 280 megawatts of electricity. Thanks to the new power source, 5,000 more schools will now have power!
