The diagram describes how coal is used to generate electricity for human activities.

It is noticeable from the picture that there are several steps, including a closed cycle, in the producing of electricity. The process begins with grinding coal into powder and ends with transmitting electricity.

At the first stage of generating electricity, the coal is moved to pulverizer in order to be crushed. In the subsequent stage, coal powder is transferred into a furnace where it is burnt to heat the water. The emission from coal combustion is released from smoke stack after treatment process in the precipitator.

Simultaneously, the water turns into steam and this steam goes through a long pipe with the turbine at the end. Then, the turbine which is linked with generator is rotated by high pressure of steam. The electricity is transmitted to a substation and travels along the power lines. Once the steam has passed the turbine, it is condensed by low temperature in cooling towers. Afterwards, this water is supplied for the furnace mentioned in the previous step.
