Geothermal Energy

What is Geothermal Energy-Spanish?

Clean, Reliable and Renewable
Geothermal energy is heat energy that comes from the molten interior deep within the earth's crust. The heat is brought near the surface due to movements in the earth's crustal plates by intrusion of molten magma and by deep circulation of groundwater.  Reservoirs of hot water under pressure are formed.

In some places, geothermal energy rises to the surface in natural streams of hot steam or water, which have been used since ancient times for bathing and cooking.

Utilization of geothermal energy is achieved by drilling of wells into reservoirs to bring heat from the hot water or steam to drive turbines in power plants.  The heat energy is thereby converted to electrical energy. 

The cooled geothermal fluid is injected back into the reservoir where it is reheated and preserves the resource mass balance and sustainability.
The Advantages of Geothermal Energy:
  • Harnesses a natural locally available energy source
  • Provides an environmentally friendly energy alternative
  • Avoids fossil fuel combustion 
  • Produces no nitrous oxide (NOx) emissions and significantly lower levels of CO2 than conventional fossil fuels
  • Baseload electricity 24/7 year-round  supply with high reliability
  • Serves as a local energy source, providing security of energy supply and price, reducing need for importation of fuel
Due to the above advantages, geothermal power has become a preferred energy source wherever economically accessible.
