Geothermal Energy

Geothermal energy Geothermal energy is an excellent energy source because it is continuously produced. Radioactive decay of long half-life nuclei embedded in the earth occupies 70% of the world's internal energy. The rest of this energy comes from the earth's strata, the gravity or the residual heat left by the collision of meteorites. Geothermal energy can be used anywhere on the earth. On average, the Earth will emit one - sixteen watts per square meter, but this number increases dramatically in areas near volcanoes, hot springs and fumaroles.

Geothermal energy is the heat generated and stored on the earth. Thermal energy is the energy that determines the temperature of a substance. Geothermal energy of the Earth's crust arises from the primitive formation of the planet and the radioactive collapse of the material (now uncertain, but probably nearly equal). The geothermal gradient, the temperature difference between the center of the planet and its surface, promotes the continuous conduction of thermal energy in the form of heat from the center to the surface. The geothermal of the adjective comes from the Greek root γη (ge) meaning earth and θερμος (thermos) meaning heat.

Before raising profits, you first need to understand geothermal energy. Geothermal is a combination of two words. Geography means the earth, heat means heat. Therefore, geothermal energy generates energy using the heat inside the crust. More specifically, geothermal energy uses water that generates water vapor in the crust. This steam is used to turn the turbine to generate electricity. Geothermal energy actually uses a process that produces energy similar to coal and natural gas. However, it avoids the need to burn fossil fuels to produce steam by using steam in hot water found in the Earth's crust. This makes geothermal energy clean and reproducible. Also, unlike intermittent renewable energy such as wind power and sunlight, geothermal energy is stable, it is an excellent base load generator.

Geothermal energy uses electricity from below the surface to generate electricity. Traditional geothermal energy utilizes steam from natural sources such as geysers and pumps to the deep part of the Earth's high temperature and high pressure. Then use hot steam to drive the electric turbine. In case of volcanic geothermal energy, heat comes from "supercritical water". Researchers explained that energy from so-called supercritical water is much higher than traditional geothermal steam. When the molten rock encounters the water, extreme heat and pressure put the water in a "supercritical" state. There, it is neither water nor liquid. In this form, water can carry more energy than normal steam, which can produce up to 10 times the output of other geothermal sources.
