Do you leave your appliances plugged in the socket when not in use? It’s all right for the electric fan but any appliance that has a pilot light consumes electricity. What we do is to plug the appliances on a surge protector with a switch. That is one convenient way of turning off the power completely. Some appliances that consumes power even when not turned on are the tv, the cable digibox, water dispenser and even the microwave particularly the model with a clock.
