Sunset and Sunrise in Geothermal Plants : Photo Credit Ormat Technologies Inc Geothermal energy is a form of renewable energy that is generated by harnessing the heat from the Earth's core. The heat is generated by the decay of radioactive elements in the Earth's crust and is conveyed to the surface through hot water and steam reservoirs. The Sun plays a role in the generation of geothermal energy because it is responsible for the Earth's internal heat. The Sun's energy heats the Earth's surface, which causes water to evaporate and become part of the hydrologic cycle. The water then seeps into the Earth's crust, where it is heated by the Earth's internal heat, and then rises back to the surface as hot water and steam. This process is known as geothermal convection. Additionally, The Sun also plays a role in the potential of the Ea...
