Geothermal energy

  1. 1. A Presentation On GEOTHERMAL ENERGY Presented BY:- Muskan mehta Ibdp student Batch-2, year-1
  2. 2. What is Geothermal Energy? • Geothermal energy refers to the energy that is generated and stored in the earth. • This energy is derived from the heat that is obtained in the earth's core.
  3. 3. • Geothermal energy is renewable energy source. • Geothermal energy belongs to energy sources that can be directly used. • Geothermal power plants have minimal land and freshwater requirements • The biggest disadvantage of geothermal energy are high upfront costs. • Small number of countries that currently harness geothermal energy. • Enhanced geothermal systems can trigger earthquakes
  4. 4. Effects Of Geothermal Energy POSITIVE EFFECTS • Useful minerals, such as zinc and silica, can be extracted from underground water. • Geothermal energy is “homegrown.” This will create jobs, a better global trading position and less reliance on oil producing countries. • In large plants the cost is 4-8 cents per kilowatt hour. This cost is almost competitive with conventional energy sources. • Geothermal plants do not require a lot of land, 400m2 can produce a gigawatt of energy over 30 years.
  5. 5. NEGATIVE EFFECTS • Extracting large amounts of water can cause land subsidence, and this can lead to an increase in seismic activity. • Power plants that do not inject the cooled water back into the ground can release H2S, the “rotten eggs” gas. • There is the fear of noise pollution during the drilling of wells.
