Transcript of Geothermal Energy!
Geothermal Energy comes from the earth's internal heat. Prince Piero Ginori Conti invented the first geothermal power plant in 1904, at the Larderello dry steam field in Italy.
10,000 years ago, near the ancient times geothermal energy was used Where Does It Come From? How Is It Renewed Geothermal Energy is not renewable as we can't grow or make new energy to replace it. It is however essentially inexhaustible as it is renewed by processes like radioactive decay and tidal friction in the magma. In simple terms, it is deemed to be a renewable energy source. Yes its a renewable source because it comes from the Earth and formed from the heat so they take advantage of the heat to make geothermal energy.
Energy created from geothermal power is safe, clean, simple, reliable and environment friendly as it is extracted from deep within the earths surface. But despite these advantages, geothermal energy is not being used widely. Geothermal energy suffers from its disadvantages as described below. Disadvantages Of Geothermal Energy Not Widespread Source of Energy : Since this type of energy is not widely used therefore the unavailability of equipment, staff, infrastructure, training pose hindrance to the installation of geothermal plants across the globe. Not enough skilled manpower and availability of suitable build location pose serious problem in adopting geothermal energy globally. High Installation Costs : To get geothermal energy, requires installation of power plants, to get steam from deep within the earth and this require huge one time investment and require to hire a certified installer and skilled staff needs to be recruited and relocated to plant location. Moreover, electricity towers, stations need to set up to move the power from geothermal plant to consumer. May Release Harmful Gases : Geothermal sites may contain some poisonous gases and they can escape deep within the earth, through the holes drilled by the constructors. The geothermal plant must therefore be capable enough to contain these harmful and toxic gases. As our reliance on fossil fuels have started to increase, geothermal energy is seen as the new source of power generation by digging out the heat stored inside the earth. Though not used fully due to factors such as location and high costs but in the years to come when fossil fuels would start to diminish, it will turn out to be the cheapest source of power generation. Geothermal energy suffers from its own advantages and disadvantages as described below. Advantages of Geothermal Energy Significant Cost Saving : Geothermal energy generally involves low running costs since it saves 80% costs over fossil fuels and no fuel is used to generate the power. Since, no fuel is require so costs for purchasing, transporting and cleaning up plants is quite low. No Pollution : This is one of the main advantage of using geothermal energy since it does not create any pollution and help in creating clean environment. Being the renewable source of energy, geothermal energy has helped in reducing global warming and pollution. Moreover, Geothermal systems does not create any pollution as it releases some gases from deep within the earth which are not very harmful to the environment Direct Use : Since ancient times, people having been using this source of energy for taking bath, heating homes, preparing food and today this is also used for direct heating of homes and offices. This makes geothermal energy cheaper and affordable. Although the initial investment is quite steep but in the long run with huge cost saving it proves quite useful Which countries or parts of the
world use this kind of energy? Top 10 Counties who use Geothermal Energy more:
1. United States
2. The Phillipians
6. New Zealand
9. El Salvador
10. Kenya Bibiliography http://www.renewableenergyworld.com/rea/tech/geothermal-energy

When the water will then be heated by the internal heat of the earth and will become steam. The steam is then used to drive a turbine which generates electrical energy. This is how they do it on Island. Flow Chart
