The diagram below shows the process by which electricity is generated in two types of hydroelectric power stations. Summarise the information by selecting and reporting the main features. Write at least 150 words.

The diagram illustrates the process by which

electricity

is produced in two types of hydroelectric power stations: a run-of-the-

river

plant

and a traditional hydroelectric

plant

. In the run-of-the-

river

plant

,

water

from a

river

is diverted into a channel.

This

water

flow

is directed towards the

turbines

, where it turns the turbine blades.

Subsequently

, the mechanical

energy

generated by the turning

turbines

is converted into electrical

energy

by the generators.

Next,

this

electricity

is conducted away from the

plant

through transmission lines.

Finally

, the

water

is released back into the

river

.

On the other hand

, the traditional hydroelectric

plant

operates

similarly

but involves a dam.

Water

from a reservoir flows through an intake, which directs it to the

turbines

. The

flow

of

water

turns the turbine blades, producing mechanical

energy

.

This

energy

is

then

transformed into

electricity

by the generators, and the

electricity

is transmitted via power lines. The

water

then

exits the

turbines

and is discharged back into the

river

. In summary, both methods efficiently convert the kinetic

energy

of flowing

water

into electrical

energy

, highlighting the use of renewable resources for power generation. The primary difference lies in the source and initial handling of the

water

flow

, with one utilizing the natural

river

flow

and the other relying on a controlled reservoir system.
