Network grid
Electricity moves across the country from different production sites to homes, offices and schools via a system known as the national grid.
The electricity created by the turbine passes through wires to electricity substations. These substations convert the electricity into smaller amounts suitable for you to use.
Every building contains a network of wires, usually through its walls and floors, that connect to various power points like wall and light sockets.
The final stop on the way is the switch. When you turn on the light switch, for instance, it allows electricity to reach that socket and enter the light bulb, turning on the light.
Energy doesn't disappear, it just changes into another form. In this case the stored energy from coal (or gas or diesel fuel) is transformed into electrical energy transferred to the grid. When you turn on the light switch you are turning it into heat and light energy.
