The laws of thermodynamics ("heat power") are the most important and universal laws of science, and the sun's heat "going forth" from its surface, provides the basic energy for all earth's processes. The First Law (conservation of energy in quantity) and Second Law (decay of energy quality) ultimately depend upon the sun's heat for their meaningful existence and operation.
