The diagram shows how electricity is generated in a hydroelectric power station. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The given picture illustrates the generation of electricity from a renewable resource, namely

water

.

Overall

, it is a man-made cycle process, which 24 hours take for one cycle. It starts in the high-level reservoir to the low-level reservoir during the day,

while

water

pumps up to its first place at night.

First,

water

from the river is stored behind the dam, which is located in a top position. During the day, the intake is opened to let the flow of liquid for electricity generation.

Then

, the

water

enters a power station, which has reversible turbines. After that, the turbines are rotated by the flow of

water

and

then

operate the generator, which is connected to the power line. The produced electricity is sent to the national grid for various uses including households and industries.

Next,

the

water

is led to the container on the downside of the station.

Finally

,during the night, the cycle is reversed. The liquid in the low-level reservoir is pumped into the upper position via reversing turbines.
