LAW OF CONSERVATION OF ENERGY: energy can neither be created nor destroyed - only converted from one form of energy to another.
LOW GRADE ENERGY: The molecules, in which this kind of energy is stored (air and water molecules), are more randomly distributed than the molecules of carbon in a coal.
HIGH GRADE ENERGY: Electrical and chemical energy are high-grade energy, because the energy is concentrated in a small space.
