The diagram below shows how geothermal energy is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

This

picture illustrates the process of generation of

electricity

by the geothermal power plant.

Overall

, The procedure of producing

electricity

starts with cold

water

going underground and it becomes warmed up by hot rocks and

then

pumped up into a condenser and after that, it is converted into

electricity

by a generator turbine.

It is clear that

, first of all, there is a cold

water

tank which is pumped down to 4.5 km under the surface of the earth by the injection well.

Secondly

, it runs through the geothermal zone horizontally until it reaches the production well,

while

it is covered by hot

water

.

Then

, it is pumped up until it goes up to the condenser tank which is placed over the surface. In the fourth step,

this

condensed hot

water

changed into steam and it flowed to the generator turbine. In the

last

step, it passes through the turbine to produce

electricity

energy.
