Here are some examples of heat energy. 1  The biggest example of heat energy in our solar system is the sun itself. 2  The sun radiates heat to warm us up one the planet earth. 3  When the burner of a stovetop is very hot, it is a source of heat energy.
(2) The other energy source is solar radiation heating the atmosphere (both by direct absorption, as well as indirectly by heat transfer from the land and water). Earthâs air develops its own convection cells that transfer the buildup of thermal energy at the planetâs surface to the upper atmosphere, where it is radiated off into space.
