Today, when energy resources are becoming scarce, it is a crime to spoil or waste energy and to charge only for the active energy consumption is no longer considered acceptable. Even the component of energy not contributing towards any useful work should be accounted for. In other words, wasted energy should be treated as energy consumed. Apparent energy is a measure of the 'Energy Delivering Potential', and, therefore, is considered most appropriate parameter for measurement of energy and tariffs. Armed with the correct definition of apparent energy and low cost apparent energy meters based on simple digital signal processing technology, It is shown how an electrical revolution can be effectively triggered - where market sees rapid sales of efficient electrical appliances. Once the revolution sets it, It is expected a disruptive but pleasant change where even appliance labels would display ratings in terms of VA instead of W.
