GEOTHERMA L ENERGY Lyka Jean T. Galera  WHAT IS GEOTHERMAL ENERGY?  comes from the Greek words geo, which means “Earth” and thermal, which means “heat”.  the energy derived form the center of Earth.  Geothermal Power Plants in the Philippines Geothermal Power Plant Location Total Installed Capacity (MWe) Tiwi Geothermal Power Plant Albay 330 Mak-Ban Geothermal Power Laguna 425.73 Plant Tongonan Leyte 722.68 Palinpinon Negros Oriental 192.5 Bacon-Manito Sorsogon / Albay 151.5 Mindanao North Cotabato 108.48  TWO TYPES OF GEOTHERMAL ENERGY  Conventional Geothermal Energy utilizes steam from natural resources such as geysers or by drawing water from the hot, high-pressure depths of Earth.  Volcanic / Supercritical Geothermal Energy naturally occurring hot water or steams flows heated by magma and circulating through permeable  How is geothermal energy generated? Geothermal energy is generated in two ways: GEOTHERMAL POWER GEOTHERMAL HEAT PLANTS PUMPS Heat from deep inside Heat coming from the Earth is used to close to the Earth’s produce steam to surface to heat water generate electricity. or provide heat for buildings.  The Geothermal Power Plant The following steps are followed to generate electricity in a geothermal power plant: Wells are drilled deep into the earth to pump stream or hot water to the surface. When the water reaches the surface, the drop in pressure causes the water to turn into steam. The steam spins a turbine, which is connected to a generator, that produces electricity. Cooling tower cools the steam which it condenses back to water. The cooled water is pumped back into Earth to begin the process again.
