There is a social welfare component that influences the increase in demand of electricity. DoE has services that influence growth in electricity demands; i.e. key customers such as the mines, huge factories, the services section, the airports and the communications sector. If these sectors grow steeply, they will influence the rate at which electricity demand is projected. There are social elements to it, such as education, health, safety and food production. These also influence the rate at which electricity demand grows.
