Electrical energy is the energy newly derived from electric potential energy or concretic energy. When loosely used to describe energy absorbed or delivered by an electrical circuit (for example, one provided by an electric power utility) “electrical energy” talks about energy which has been converted from electrical potential energy. This energy is supplied by the combination of electric current and electrical potential that is delivered by the circuit. At the point that this electrical potential energy has been converted to another type of energy, it ceases to be electrical potential energy. Thus, all electrical energy is potential energy before it is delivered to the end-use. Once converted from potential energy, electrical energy can always be called another type of energy (heat, light, motion, etc.).
