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.
