9. Origin of Geothermal Energy Where does this heat come from?
The word "geothermal" comes from the Greek words ‘geo’, meaning earth, and ’therme’ meaning heat. Geothermal energy is the heat contained in the earth crust.
Origin of this heat is linked with the internal structure of our planet and the physical processes occurring inside.
Where does this heat come from?

10. What is a Geothermal Reservoir?
A geothermal reservoir is a volume of rocks in the subsurface from which exploitation in terms of heat can be economically profitable.
When a large volume of hot water and steam is trapped in subsurface porous and permeable rock structure and a convective circulating current is set up, it forms a geothermal reservoir

11. Where do we find a Geothermal Reservoir?
Reservoirs can be suspected in the areas where we find :
Geysers
Boiling mudpots
Volcano
Hot springs
Fumaroles
Reservoirs can be discovered
Testing the soil
Analyzing underground temperature

15. Positives of Geothermal Energy
Renewable and Environment Friendly source of Energy.
No burning of fuels and hence no harmful emission (CO2 , CO or any other greenhouse gases)
Reliable source of energy and can be operated 24 hours a day.
Very low operation and maintenance effort and cost.
Smallest footprint on the surface.
