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.

The given illustration depicts the process of production of

electricity

by utilizing geothermal energy in a geothermal power plant.

This

process uses the heat from deep under the earth’s surface for the purpose of generating

electricity

.

Overall

, there are five steps in the procedure for

electricity

generation. To generate electric power, cold

water

is used. The cold

water

, which is stored in a rectangular reservoir on the surface of the earth, is pumped down to a depth of 4.5 km. In the second

step

, the

water

reaches the injection well. From the injection well, the

water

travels horizontally through the geothermal zone that consists of hot rocks. Having passed through

this

zone, the heated-up

water

reaches the production well in the third

step

. From the production well,

water

is pumped back up to the surface of

earth

. From the condenser, the

water

, now in form of steam, passes through a narrow, short pipe.
