Electricity

Electricity is a form of energy that results from the presence and flow of electric charge, usually carried by electrons.

How it works

When electrons move through a conductor such as a copper wire, they create an electric current. Voltage pushes the current, which can power devices, produce heat and light, and drive motors.

Generation

Electricity is generated in power stations from sources such as coal, gas, water, wind, solar energy and nuclear power, then delivered to homes and industry through the grid.
