The diagram shows how electricity is generated by a hydroelectric dam. Write a 150-word report for a university lecturer explaining how the process works.

The diagram illustrates how electricity is produced in a hydroelectric power station. The process is shown for both daytime and nighttime. Overall, during the day water flows down from the high-level reservoir to generate electricity, while at night it is pumped back to the upper reservoir. Initially, water from the river is stored in a […]

The diagram illustrates how electricity is generated from a water dam using hydroelectricity, which is why people generally refer to it as a hydroelectric dam. Overall, in this process, water is the main source of electricity generation. As we can see in the diagram, the water from the reservoir travels through a penstock. The penstock […]
