Geothermal Energy The word defined is – energy generated by heat stored in the earth, or the collection of absorbed heat derived from underground, in the atmosphere and oceans.
Geothermal Electricity Hot water or steam from below ground can also be used to make electricity in a geothermal power plant. These areas have so much steam and hot water that it can be used to generate electricity. Holes are drilled into the ground and pipes lowered into the hot water, like a drinking straw in a soda. The hot steam or water comes up through these pipes from below ground. A geothermal power plant is like in a regular power plant except that no fuel is burned to heat water into steam. The steam or hot water in a geothermal power plant is heated by the earth. It goes into a special turbine. The turbine blades spin and the shaft from the turbine is connected to a generator to make electricity. The steam then gets cooled off in a cooling tower. So is like a regular power plant, they just gives the environment a little break.
Some of the closest places are in California, there are 14 areas where we use geothermal energy to make electricity.There are some areas not used yet because the resource is too small, too isolated or the water temperatures are not hot enough to make electricity.
The main spots are: the Geysers area north of San Francisco, in the northwest corner of the state near Lassen Volcanic National Park, in the Mammoth Lakes area - the site of a huge ancient volcano. The Coso Hot Springs area in Inyo County, and in the in the Imperial Valley in Southern Califorina
Hopefully in the future most of the world will be powered with geothermal electricity. I guess the problem is to transport the energy. Do not get me wrong there are some bad sides to it.
