The diagram below shows how geothermal energy is used to produce electricity.

The chart presents the

process

of producing electricity from geothermal energy.

Overall

, the whole

process

does not require any human involvement. Obviously,

water

is required in the

process

; it is turned into steam that powers the

turbine

.

First,

the

water

stored in the tank on the ground is sent down to the injection well which is located at the depth of 4.5 kilometres under the ground.

Then

, the

water

runs past the tube which absorbs the heat from hot rocks at the geothermal zone to warm the

water

. The

water

is

then

stored in the production well, located as deep as that of the injection well before being pumped up to the condenser above the ground. At

this

stage, the hot

water

from underground is condensed and turned into steam which goes past the tunnel to turn on the

turbine

. The

turbine

is operated by steam power, which comes from the condensation

process

at the condenser. The wind from the

turbine

passes to the generator to create the magnetic field, at which the electricity is produced before it is sent to the electricity post which passes the electric current to households.
