GEOTHERMAL ENERGY
GEOTHERMAL ENERGY• “Geo” – EARTH, “Thermal” - HEAT• The natural heat of the Earth.• Originates from the original formation
of the planet (20%) and from radioactive decay of minerals (80%).
• The heat that is used for geothermal energy can be stored deep within the Earth, all the way down to Earth’s core – 4,000 miles down.
GEOTHERMAL ENERGY
ADVANTAGES of GEOTHERMAL ENERGY× Natural Source of Energy
× Environment Friendly
× Power Plant is Less Invasive
× Significant Cost Saving / Less expensive
× Reduce Reliance on Fossil Fuels
× High Load Factor
× Geothermal Power is Self-Sufficient
× Independent of the Weather
1. Not widespread source of energy2. High Installation Costs3. Longevity
4. Transportation
5. Hazardous Materials
6. Earthquakes

Geothermal plants around the globe
• The world’s first geothermal power station:
– Larderello, Southern Tuscany, Italy
– Built in 1911
Geothermal plants around the globe
• Larderello Worlds First Geothermal Power Station contributed to:– Supplying power to a
million of houses globally.– 5000 GWh yearly
production– 10% of the world's total
geothermal electricity production.

Geothermal Power Plants around the Globe
1. Cerro Prieto Geothermal Power Station
– largest geothermal power station in the world
– Installed capacity of 720 MW
– plans for expansion up to 820 MW by 2012.
– located in south Mexicali, Baja California, in Mexico, and is built in five individual units, namely CP1, CP2, CP3, CP4 and CP5.
