Geo-thermal Energy
✓
Answer
The geo-thermal energy is a non conventional source of energy. It is pollution-free. eco-friendly and is always available. The vapour formed in the interior of the earth comes to the surface due to tectonic movements. The energy which is obtained by controlling this vapour is called Geo-thermal energy.
The temperature increases as we go deeper in the interior of the earth. Occasionally that thermal (heat) energy is reflected in the form of hot water streams on the surface of the earth. This heat energy can be used to generate power. Since several years geo-thermal energy in the form of hot water spring has been used by people for cooking, to get heat and to take bath.
The largest geo-thermal power plant of the world is located in $USA.$ Geo-thermal energy is used also in New Zealand, Iceland, Philippines Italy and Japan.
The geo-thermal power plants are located at Manikaran in Himachal Pradesh and at Pugaghati of Union Territory of Ladakh.
Hot water springs (Geysers) are located at Lasundra. Unai. Tuva and Tulsishyam in Gujarat The geo-thermal energy is likely to be found at these places.
