3. WHAT?
 “Geo” refers to “Earth & earth related” in Greek
 “Thermal” refers to “Heat & heat related” in Greek
 So as the name suggests ,geo thermal energy refers to creation of energy with the help of heat
produced in earth’s crust and turning the heat energy into electrical energy with the help of a
turbine
 It produces surplus amount of energy in many parts of the world and it is considered as one of
the most economical sources of renewable energy.

4. HOW?

5. Where?
 ICELAND IS THE MAJOR USER OF GEO THERMAL ENERGY
 USA,MEXICO,BAHAMAS ARE HAVING MORE NUMBER OF GEO THERMAL POWER PLANTS AS
THEY ARE LOCATED IN THE INFAMOUS “ RING OF FIRE” IN THE PACIFIC OCEAN
 EAST COAST OF AFRICA
