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 diagram provided illustrates the process of electricity generation using geothermal

energy

. In general Geothermal

energy

harnesses the Earth's internal heat to generate electricity, making it a sustainable and reliable

energy

source. Cold

water

is injected into the Earth through an injection well, reaching a depth of approximately 4.5 kilometres. The injected cold

water

moves to the geothermal zone, where it encounters hot rocks.

This

area contains a high concentration of heat which is absorbed by

water

heat from these rocks, transforming into hot

water

or

steam

. The heated

water

or

steam

is

then

pumped back to the surface through a production well. The

steam

or hot

water

is directed to a condenser. In the condenser, the

steam

is cooled back into

water

after transferring its

energy

to drive the turbine. The

steam

powers a turbine, which is connected to a generator. As the

steam

passes through the turbine, it causes blades to spin, converting thermal

energy

into a mechanical one. The generator

then

converts

this

mechanical

energy

into electrical currency, which is supplied to the power grid.
