The diagrams below show two methods of using water to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Hydroelectric dam

The diagram gives information about the mechanism of hydroelectric power generation.

Overall

, it can be clearly seen that there are eight stages to converting

water

becomes

electricity

. The process begins with evaporation which uses seawater as a main source and finishes with the distribution of

electricity

through underground cables to supply hospitals or schools power. Look at the diagram in more detail, First and foremost, seawater has been evaporated by the sun and turned into clouds that contain the

water

.

Subsequently

, the clouds move to some areas and the rain occurs gathering

a dam as a reservoir. In

this

system, there is a pipe that transfers

water

from the dam through a valve (open and close) to a turbine that resulting a reaction which produces

electricity

.

While

electricity

comes up through high voltage cables, the

water

from a turbine is sent to the pump machine and is pumped back to the dam.

The next step is

electricity

that is

conducted from high voltage cables’ towers to the transformer station. From

this

point onwards, the undergone cables are set up through the areas to cover a wide range of amenities including residences, manufacturers, and hospitals or schools.

Finally

, the

electricity

is able to be used by people in those buildings.
