earth's crust
section::::renewable sources.:geothermal.









































geothermal energy is thermal energy generated and stored in the earth. thermal energy is the energy that determines the temperature of matter. the geothermal energy of the earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). the geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. the adjective "geothermal" originates from the greek roots "γη (ge)", meaning earth, and "θερμος (thermos)", meaning hot.
