Where Does The Heat For Geothermal Energy Come From
Olivia Luz
The molten core of planet earth is the source of heat for geothermal energy.
Most pockets of low temperature geothermal energy are found just a few meters below ground. Low temperature geothermal energy is obtained from pockets of heat about 150 c 302 f. Low grade heat stored in the shallow subsurface 200 m is largely derived from solar radiation that is absorbed by the ground and distributed via natural groundwater systems and artificial structures such as flooded coal mines. Geothermal energy comes from the earth s core.
The average heat flow from the earth s surface is 87mw m 2 that is 1 10 000th of the energy received. The geothermal energy of the earth s crust originates from the original formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. Thermal energy is the energy that determines the temperature of matter. Geothermal energy is the heat that comes from the sub surface of the earth.
The adjective geothermal originates from the. The used geothermal water is then returned down an injection wellinto the reservoir to be reheated to maintain pressure and to sustain the reservoir. Geothermal energy is the thermal energy generated and stored in the earth. From underground from steam directly from the earth.

The term geothermal energy refers to any heat derived from the ground from depths of a few metres to multiple kilometres beneath the earth s surface. The heat from this comes from when the earth was first formed. Low temperature geothermal energy can be used for heating greenhouses homes fisheries and industrial processes. Compression and contraction of the earth by our lunar and solar orbits radioactive.
