We all know that the earth produces some heat below its surface in the deep interiors. The temperature at which this heat is produced is far much higher than the actual temperature of the sun’s surface. This heat generated under the earth’s surface can be used as a renewable energy source called geothermal energy. The heat at which this heat is produced is so high that energy can not uphold itself below the surface and so it finds a way through volcanoes, hot springs and fumaroles to appear at the surface of the earth..
A large part of the geothermal energy resources are found near the Pacific Ocean. Pacific Ocean comprises of a Ring of Fire where a significant amount of geothermal energy is produced as an alternative energy source. This alternative energy source produced from the molten core of the earth is mainly used to produce electricity. This magma is available in abundance below the earth’s surface and this is the reason why geothermal energy is considered to be a renewable energy source.
Electricity produced from the geothermal energy resources uses technologies namely, binary technology or flash technology. In the flash technology, the water available at extremely high temperatures as a geothermal energy resource is super heated to produce steam, which then drives to a turbine to generate electricity. In the binary technology, heat of the geothermal water is transferred to another liquid to produce vapors which then drive turbines for producing electricity. This electricity produced by the use of geothermal energy can be further used for several other purposes.
