Geothermal EnergyGeothermal Energy has been around for as long as the Earth has existed.
"Geo" means earth, and"thermal" means heat. So, geothermal means earth-heat.Have you ever cut a boiled egg in half? The egg is similar to how the earth looks like inside. Theyellow yolk of the egg is like the core of the earth. The white part is the mantle of the earth. Andthe thin shell of the egg, that would have surrounded the boiled egg if you didn't peel it off, is likethe earth's crust.16Below the crust of the earth, the top layer of the mantle is a hot liquid rock called magma. Thecrust of the earth floats on this liquid magma mantle. When magma breaks through the surface ofthe earth in a volcano, it is called lava.For every 100 meters you go below ground, the temperature of the rock increases about 3 degreesCelsius.
Or for every 328 feet below ground, the temperature increases 5.4 degrees Fahrenheit. So,if you went about 10,000 feet below ground, the temperature of the rock would be hot enough toboil water.Deep under the surface, water sometimes makes its way close to the hot rock and turns intoboiling hot water or into steam. The hot water can reach temperatures of more than 300 degreesFahrenheit (148 degrees Celsius). This is hotter than boiling water (212 degrees F / 100 degreesC). It doesn't turn into steam because it is not in contact with the air.When this hot water comes up through a crack in the earth, we call it a hot spring, like EmeraldPool at Yellowstone National Park pictured on the left.
Or, it sometimes explodes into the air as ageyser, like Old Faithful Geyser pictured on the right.About 10,000 years ago, Paleo-Indians used hot springs in North American for cooking. Areasaround hot springs were neutral zones. Warriors of fighting tribes would bathe together in peace.Every major hot spring in the United States can be associated with Native American tribes.California hot springs, like at the Geysers in the Napa area, were important and sacred areas totribes from that area.In other places around the world, people used hot springs for rest and relaxation. The ancientRomans built elaborate buildings to enjoy hot baths, and the Japanese have enjoyed natural hotsprings for centuries.Geothermal TodayToday, people use the geothermally heated hot water in swimming pools and in health spas.
Or,the hot water from below the ground can warm buildings for growing plants, like in the greenhouse on the right.In San Bernardino, in Southern California, hot water from below ground is used to heat buildingsduring the winter. The hot water runs through miles of insulated pipes to dozens of publicbuildings. The City Hall, animal shelters, retirement homes, state agencies, a hotel and conventioncenter are some of the buildings which are heated this way.In the Country of Iceland, many of the buildings and even swimming pools in the capital ofReykjavik (RECK-yah-vick) and elsewhere are heated with geothermal hot water.
