Green Energy

Geothermal energy is thermal energy generated and hold on within the Earth. Thermal energy is that the energy that determines the temperature of matter. The heat of the Earth's crust originates from the initial formation of the earth and from decay of materials (in presently uncertain however presumably roughly equal to proportions). The energy gradient, that is the distinction in temperature between the core of the earth and its surface, drives a nonstop conductivity of thermal energy within the kind of heat from the core to the surface. The adjective energy originates from the Greek roots earth, and (thermos), that means hot.
