  • Geothermal energy is produced by drilling a well into the ground where thermal activity is occuring. Once a well has been identified and a well head attached, the steam is separated from the water, the water is diverted through a turbine engine which turns a generator. Usually the water is injected back into the ground to resupply the geothermal source.
  • Geothermal energy is captured by using the heat below the outer layer of the earth's crust.  By pumping water below the surface at "hot spots" where the earth's crust is thinner, the water is turned into steam.  The steam is used to turn turbines and generate electricity.  Hot spots are found all over the world,  they are a very efficient and clean resource for energy.  In Northern California the Geysers encompass a 30 acre field that, now retrofitted with a system to recycle treated waste water, will generate 880 megawatts per hour through 21 generating plants - enough energy for the entire Northbay or the city of San Francisco.

    • 1. Geothermal Energy
    • 2. o The Erth absorbed the 50% of energy of the sun´s radiations
    • 3. o Radioactive decay is the process by atomic nucleus of the some minerals spontaneously loses energy by emitting ionizing particles and radiations of hight temperatures
    • 4. o The Soil has four layers o Each layer has different compositions, functions…o …and temperatures.
    • 5. o The heat of theearth radiatesoutwards, heatingthe rocks and water
    • 6. o Geothermal energy is generally harnessed in areas of volcanic activityUnited States 2,850Philippines 1,848Italy 768.5Mexico 743Indonesia 589.5Japan 530New Zealand 345Costa Rica 120Iceland 140El Salvador 105
    • 7. o The heated water can reach the surface and form hot springs and geysers
    • 8. o Geothermal energy is produced by drilling a well into the ground where thermal activity is occuringo The water is goes through a turbine engine which moved a generatoro Usually the water is injected back into the ground to be supplied again
