Geothermal power presentation

  1. 1. Geothermal Electricity <ul><li>By Joshua Greenaway, Raymond Catto and Scott Brown </li></ul>
  2. 2. So what is Geothermal Electricity? <ul><li>Geothermal Electricity is electricity created through use of the heat in or on the Earths surface. </li></ul><ul><li>It can be created through hot rock or water found deep in the earth, or through use of steam from hot springs. </li></ul><ul><li>The most powerful source for this electricity, would be magma, but unfortunately, as of yet there is no available technology to harness it’s heat. </li></ul>
  3. 3. How is this Electricity generated? <ul><li>Geothermal energy is produced in three different kinds of plants, ‘Dry Steam’, ‘Flash Steam’ and Binary cycle. </li></ul><ul><li>Dry steam plants take steam directly from the underground sources and using pipes, direct it to the turbines that power the generators. </li></ul><ul><li>Flash steam energy is produced through the welling of extremely hot water which, as it rises, causes steam which is channeled to the turbines. </li></ul>
  4. 4. How is this Electricity generated? (Continued...) <ul><li>Binary cycles plants use the heat from hot water to boil an organic compound fluid with a low boiling point. The steam produced from the boiling fluid is used to spin the turbines, powering the generator. </li></ul>
  5. 5. Advantages of Geothermal Energy <ul><li>Geothermal energy saves costs. The energy saves 80% costs over fossil fuels such as coal and no fuel is actually needed. </li></ul><ul><li>Use of alternative energy sources such as Geothermal energy reduces the use of fossil fuels and our overall dependence on them. This is particularly helpful considering the rising costs of oil. </li></ul>
  6. 6. Advantages of Geothermal Energy (Continued...) <ul><li>Geothermal energy is also environmentally friendly. Unlike fossil fuels, it is a renewable energy source and has virtually no carbon footprint whatsoever as the only gasses it releases from the earth, are ones that are not harmful to the environment at all. </li></ul><ul><li>Geothermal energy can also be used as a direct source for heating water for baths or cooking, and can also be used to heat homes and buildings. </li></ul>
  7. 7. Advantages of Geothermal Energy (Continued...) <ul><li>Use of this energy also has the economic benefit of creating employment. </li></ul>
  8. 8. Disadvantages of Geothermal Energy <ul><li>Geothermal plants lack of worldwide spread poses issues for training, resources and infrastructure. </li></ul><ul><li>Though geothermal energy is cheap to run, it can be expensive to set up a plant for its production. This can be said for a lot of different energy sources though, including fossil fuels. </li></ul>
  9. 9. Disadvantages of Geothermal Energy (Cont...) <ul><li>Geothermal sites can also run out of steam slowly over time, making huge investments in the sites worthless for the companies. </li></ul><ul><li>Huge amounts of research are needed to find a suitable place for a geothermal energy plant to be located. </li></ul>
  10. 10. Disadvantages of Geothermal Energy (Cont…) <ul><li>Though Geothermal sites may not harm the environment, they can still pose a threat to human life as they can release poisonous gasses trapped in the earth into the air. </li></ul>
  11. 11. Effectiveness of Geothermal Power <ul><li>Though Fossil Fuels are a non-renewable source of energy, Geothermal Power is constant and renewable. This is good since Geothermal Power doesn’t negatively impact the environment. </li></ul><ul><li>Fossil Fuels produce green house gasses into the environment causing a lot of pollution and global warming, whereas Geothermal Power is cleaner and produces no pollution. </li></ul>
  12. 12. Effectiveness of Geothermal Power (Cont...) <ul><li>Fossil Fuels are rapidly decreasing meaning we may have no access to this source of energy in the near future. Geothermal Power, on the other hand, is renewable which means we can access it forever. </li></ul><ul><li>The strength of Geothermal Power can power several cities, whereas average power plants do not have that capacity. </li></ul>
  13. 13. How safe is Geothermal Power <ul><li>It is dangerous to drill in the area of the site. </li></ul><ul><li>The strength of Geothermal Power can power several cities, whereas average power plants do not have that capacity. </li></ul>
