What are the sources of heat

    The two major sources of heat for the world are the Sun and the core of the earth. Other than that, fire and light are probably the most common man-made forms of light out there.

    To get a bit more technical, the ultimate source of heat is the kinetic energy that causes molecules to move around and then collide with one another, generating friction.  Frictional force allows kinetic energy to be converted into heat. 

    Note that: “Heat always refers to the transfer of energy between systems (or bodies), not to energy contained within the systems (or bodies).”

    On a grander scale, yes, solar and geothermal power are going to be the most significant sources of heat.
