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

This

diagram depicts stages of energy production from rivers and dams. It is clear from the graph that the river moves through a dam

reach to the power station and to settle in a reservoir.

According to

what is shown, the river gathers at the dam in the night and is allowed to pass in the daytime.

Following

this

it crosses from the bottom of the dike to the power generator.

Next,

it moves to the reverse turbine, which transfers the water to a small reservoir during the day and returns it to the barrier at night so that energy is generated during the passage through it. After that, the power is transmitted through cables from the generator to the national grid for distribution.

To sum up

, we could say that the hydroelectric undergoes two reservoirs for crosses from reversible turbines to move it and generate energy from the flow of water without any carbon dioxide emission.
