What is earth internal energy source?

How much heat does the earth generate?

Very little. The Earth’s surface emits about 503 watts per square meter (398.2 W/m2 as infrared radiation, 86.4 W/m2 as latent heat, and 18.4 W/m2 via conduction/convection), or about 260,000 terawatts over all of the Earth’s surface (Trenberth 2009). The ultimate source of almost all of this energy is the Sun.
