The diagram below shows how geothermal energy is used to produce electricity. Summarise the information by selecting and reporting the main feartures, and make comparisons where relevant.

The illustration presents the process of producing

electricity

by using geothermal energy.

Overall

,

This

process takes advantage of the difference in temperature between the terrestrial surface and the inside of the earth to gain energy by using

water

as a medium. The natural energy is converted by the mechanical steam machine to

finally

create

electricity

.

First,

the cold

water

is pumped down to the injection well underground which is around 4.5 kilometres from the surface. The

water

is transported and boiled by the hot rocks through the geothermal zone where the temperature is hot from the injection well to the production well.

Next,

the hot

water

is pumped up to the condenser where the

water

is transformed into vapour.

Then

, The vapour goes into the turbine

that is

powered by steam to generate power for the

electricity

generator. After that, the generator produces an electric magnetic field to produce

electricity

. Eventually, the

electricity

Is moved to the electrical post to distribute the

electricity

for house use.
