İ believe that using alternative resources is really crucial both for today and for future. Geothermal energy is one of them. So what does geothermal mean? The term comes from two Greek words, "geo" which means earth and "thermal" means hot. So, the energy is gained by the heat from the world. At the core of the world, temperatures may reach 5000 C. Heat from the centre of the earth cause some rocks underground melt and becomes molten as we call it magma. The magma heats rock and water in the crust.
The Earth's geothermal resources are more than adequate to supply the energy needs of people. Also, it is renewable. Because any heat extraction is small when you compare with the Earth's content.
What are the advantages of geothermal energy?
