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

 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.

 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.

 In the Netherlands they have good design and engineering of geothermal wells.  People 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.

One use is for heating homes and other buildings. One use is for heating homes and other buildings. Also its used for generation electricity. Also its used for generation electricity. To get energy we use geothermal pumps. To get energy we use geothermal pumps. It’s a clean source of energy and does not run on fossil fuels.

In the United States, most geothermal reserves are in Nevada and California. In the United States, most geothermal reserves 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. 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) The temperatures are in between 50°F and 60°F (10°Cand 16°C) It can easily be found along the “Ring of Fire”.

Charges in cold or hot water. Charges in cold or hot water. Heat pump for heating in the summer. Heat pump for heating in the summer. Has a cooling and heating pump also used for heating. Has a cooling and heating pump also used for heating.

ATES stands for aquifer thermal energy storage. ATES stands for aquifer thermal energy storage. High temperature ATES/BTES (the pilot stage). High temperature ATES/BTES (the pilot stage). Is a direct heating system by storage of waste heat. 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.

Geothermal energy is heat stored within the Earth. Geothermal energy is heat stored within the Earth. The center of the Earth is a core made of molten metal. 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. 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. This is hot enough to melt the surrounding rock, turning it into magma. Then the magma rises to the surface and heats the ground. Then the magma rises to the surface and heats the ground.

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