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 illustrates the process of creating alternative electricity

power

in a geothermal

power

plant which contains 5 states in detail from the cold

water

tank to the

power

grid.

Overall

, it can be clearly seen that the process of electricity making by geothermal has 2 sections: under the

ground

and on the

ground

.

In addition

, they use a natural capability,

such

as hot rock to make hot

water

. In the first

step

, the process begins underground with the

water

in the cold-

water

tank (placed on the

ground

) being pumped by the cold-

water

pump through the injection well (

step

2). After that, the

water

is heated by the hot rock in the geothermal zone and pumped up to the

ground

surface by the hot

water

pump(

step

3). After being pumped to a high elevation, hot

water

becomes steam in the condenser(

step

4)

then

the turbine is rolled by steam

then

electricity is generated to the generator before being transmitted to the

power

grid.
