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.
The diagram illustrates the day-to-night steps of the generation of
electricity
from a hydroelectric power station.
Firstly
, the river flows into the high-level reservoir
which is blocked by a dam to preserve water
. During the daytime, when the intake below the dam is open, the water
flows from the high-level reservoir
through reversible turbines in the power station which operate as generators to the low-level reservoir
. As turbines spin while
water
runs through, they will generate electricity
which will later be transmitted to the national grid through power lines and then
be distributed for use. In contrast
, during the nighttime, reversible turbines work in a reserve way, which means they will pump water
back into the high-level reservoir
from the lower one as the intake of the dam is closed.
As the diagram displays, the generation of electricity
from hydroelectric stations does not involve any procedure that is
harmful to nature. In conclusion, it is an environmentally friendly way to produce electricity
