Significance of saving one unit of electricity

Recent survey and studies on saving of electricity have concluded that the significant portion of electricity is being wasted due to improper use of electrical appliances mainly in domestic and corporate Sectors. This paper deals with an approximate calculation which shows the effect of saving one unit of electricity per week per customer annually. The losses and efficiency is analysed at transmission and distribution stages of power system network to find actual energy needed to supply one unit of energy to the end user. We have calculated the amount of emission of CO₂, SO_X, NO_X and other gases, which are produced while burning the coal, that get mixed with the atmosphere causing greenhouse effect and one of the main reason behind global warming. We have also calculated the amount of air, heat energy, and oxygen required to burn the coal. Finally the cost of energy (coal cost) saved annually at the national level is examined. It is targeted to provide the detailed information and awareness to the consumer for conserving the energy and avoiding the improper use of appliances and devices.
