  1. Geothermal Energy! Adelaide Aquilla, Anne Kish, Walter Lempke, Katherine Barber

  2. What Geothermal Energy Is • Geothermal energy- the energy produced by heat within the Earth. • Geothermal energy can be found in volcanoes, hot springs, and geysers. • Geothermal energy is a green house gas and does not produce waste.

  3. Power Plants • Geothermal power plants are built in areas where the Earth produces hot water or steam. • Today, there are almost 150 geothermal power plants that are found in Iceland, Italy, New Zealand, and the United States. • Geothermal energy can be found in certain places around the world so therefore geothermal power plants can only be formed in certain places around the world

  4. Power Problems • When heated water is taken from the ground the rocks become very dry. • The rocks may shift or break causing tiny earthquakes. • Workers have to be extremely careful where they place geothermal power plants • In deserts they produce very little geothermal energy because of the lack of ground water.

  5. Netherlands • In the Netherlands they have good design and engineering of geothermal wells. • People must drilling these wells must have supervision on behalf of the client. • The maintenance and repair of geothermal wells and installations take a lot of time and money.

  6. The Uses of Geothermal Energy • One use is for heating homes and other buildings. • Also its used for generation electricity. • To get the energy we use geothermal pumps. • It’s a clean source of energy and does not run on fossil fuels. • Geothermal energy supplies less than 10% of the world’s energy.

  8. Locations • In the United States, most geothermal reservoirs are in Nevada and California. • Almost everywhere that has shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature. • The temperatures are in between 50°F and 60°F (10°Cand 16°C) • It can easily be found along the “Ring of Fire”

  9. Boreholes • Boreholes: a heating system to get geothermal energy. • Ground source heating pump, for heating • BTES and heat pump for heating and limited a cooling system

  10. Aquifer Thermal Energy Storage • Aquifer Thermal Energy Storage: a cooling/heating system • Cooling only not for heating • Charges in cold or hot water • Heat pump for heating in the summer • Has a cooling and heating pump also used for heating

  11. High Temp. ATES/BTES • ATES stands for aquifer thermal energy storage • High temperature ATES/BTES (the pilot stage) • Is a direct heating system by storage of waste heat. • Some foreign firms that are joining forces with the US companies that specialize in geothermal energy storage are discussing the ATES

  12. Heat From Magma Under the Ground • Geothermal energy is heat stored within the Earth. • The center of the Earth is a core made of molten metal. • The temperature at the Earths core is at least as hot as the surface of the sun. • This is hot enough to melt the surrounding rock, turning it into magma • Then the magma rises to the surface and heats the ground.

  13. Disadvantages • A disadvantage of geothermal energy is it is expensive the price is $1, 500 to $3,000

  14. Fun Facts • Geothermal energy is gathered by a tube. • To gather and store geothermal energy it usually costs 1,150 -3,000. • The amount of energy gathered is very little compared to other energy sources. • It is renewed by all of it resources.

  15. Review Questions • Why can you not have a geothermal power plant in the desert? • Because there is not a good supply of ground water. • What is a borehole? • A heating system to get geothermal energy.
