2. Different Geothermal Energy Sources

3. The areas in the world with the higher underground temperatures are regions with active
volcanoes. These “hot spots” occur at tectonic plate boundaries or where the earth’s crust is
thin enough to let the heat through.

9. Homegrown Energy
It is a renewable resource
Low maintenance charge
produces 4 times the energy that
they consume
Additional capacity can be added to produce more power
Less area is required
Unlike solar energy or wind
energy, it is not dependent on
the weather conditions
There is no wastage or
generation of by-products
Constant supply of energy
Positive Attributes

10. Demerits
