In each house there are many type of electric equipment that runs on electricity. Many of them we have to make them run 24 hour like the fridge if we turn it off the food will become unsuitable, water pressure to make the water reach all the rooms and the kitchen and security alarm to make the house safe. Other types of electronics like television, radio and water heater. For the television and radio we used them for a short time when we finish of using them we just made in stand by, when they are in stand by them still using electricity so we have to shout them down from the main source of power. Water heaters also use electricity when we do not use it we should just turn it on when we take the shower.
