Excerpt from Information: Elementary Electricity, Motor Car Electric Systems and Delco Light For example - A gasoline engine will run only as long as the supply of energy (in the form of gasoline) lasts. When this supply runs out, the engine stops. Part of the original energy is changed into a form of energy called heat, which is gradually absorbed by the air and objects with which the heat comes in contact. This represents a wastedor lost part of the original energy. Part of the energy is changed into mechanical motion (which is simply energy in another form), by the action of the piston, connecting rod, crankshaft, etc. This represents the useful part of the original energy, and this in turn can again be changed into other forms by using it up in operating various machines, both mechanical and electrical. When a generator is driven, the power necessary to drive it is obtained from the energy transmitted through the crank shaft of the engine. The en ergy is thus transformed into another form which we call electricity, or rather electricity is generated and by means of the electricity, energy can be transmitted from the gener ator to any desired point by means of suitable conductors wires). By the use of an electric motor, the energy transmitted by electricity can again be changed into a mechanical form and used to drive various mechanical machines. Or, the energy transmitted by the electricity can be changed into the form of heat, and when the heat is made use of in an electric lamp we obtain light. Energy may also exist, and be stored in a chemical form. Explosives, such as gunpowder, nitro-glycerine, etc., are examples of stored energy with which everyone is familiar.
