We are no longer dependent upon antiquated techniques of operating industrial plants and providing heat and light to our communities. Physics allows us to explore the nature of electricity and magnetism. We refer to energy resources as those natural substances that provide us with heat, light, electricity, modes of transportation and necessities for comfortable livelihood. The sun, wood, water, natural gas, nuclear reactors, wind and fossil fuels all serve as sources of energy. Each of these resources may provide energy in a different way, but the purpose is the same.
Energy resources serve as mediums for improving our quality of life.
The nucleus of an atom is very minute, yet it can be manipulated to provide megaunits of energy to industrial plants. It can generate enough energy to launch a rocket into space and set it into orbit for an extended period of time. It can produce enough electrical power to supply an entire community, or it can produce enough force to destroy an entire country. It is increasingly becoming usefull in medicine. Nuclear energy can be quite useful or violently destructive.
