Concept Explanation
 

Renewable Source - Geothermal Energy

Renewable Source - Geothermal Energy: Geothermal energy is the energy obtained from the heat of the earth. Geothermal energy does not depend directly or indirectly on solar energy. The interior region of the earth below its crust is very hot and it consists of molten rocks called 'magma'. Magma is in semi-solid state. The geological changes push this semi-liquid magma towards upper surface and it gets collected at some depth below the surface of the earth. These places are called 'hot spots'

Hot spots are considered as the sources of geothermal energy. When the underground water comes in contact with such hot spots, it turns into steam which is trapped in the space between rocks and becomes compressed due to high pressure. This steam can be collected by introducing pipes after drilling holes. These pipes reach up to the depth of hot spots. The steam coming up through the pipes can be used to run turbines. Sometimes the steam finds its way throngh the cracks in the crust and comes up to the surface in the form of geysers. The steam from such geysers has the temperature of about 150 -200°C. Geothermal energy is am co-mendly source of energy and the cost of electricity generated from it is almost hair that of the electricity generated using conventional methods.

A large number of geysers are found in USA and New Zealand but we have limited places in India for geothermal energy. In Gujarat, we have geysers at places like Unai, Tulsi Shyam in Saurashtra, and geothermal energy. In Gujarat, we have geysers at places like Unai,Tulsi Shyam in Saurashtra, and  Lasundra and Tuva villages in Godhra District.

Advantages:

1. This energy is available throughout the year.

2. The cost of production is comparatively low.

3. It is eco-friendly, i.e. pollution-free.
