The sun, created by God, is the source of all energy on earth. Life here cannot exist without sunlight. Coal and oil are chemical energy from fossil plants. Food is transformed by digestion and metabolism into work energy and muscle movement, production energy for making enzymes and hormones, and electrical energy for nerve cells and all other body activities.
Heat is produced to maintain warmth in the boy.
Except for atomic energy and God's creation of the world, we normally think of energy as being transferred from one state to another - neither created nor destroyed. The fact that light was the first thing created during creation week is evidence of its environmental importance. Its benefits are so clear that one can understand why so many throughout history have worshipped the sun. The remaining one percent is made up of cosmic rays, gamma rays, x-rays, radio waves, and electric waves. Sunlight helps purify the environment by killing germs.
