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 picture illustrates the usage of geothermal energy in producing electricity. Based on the image, the process is divided into five steps where the first three actions happen underground

while

the rest of the process is conducted on the upper ground. The first three processes that happen underground, start with cold

water

pumped down to the 4.5

deep underground. Once the

water

reaches the tip of the geothermal zone, it will pass through an injection well to enable the

water

to flow through the pipe

that is

surrounded by hot rocks in the

of the geothermal zone.

Subsequently

, the

water

becomes boiled and

then

gets into the production well that pumps the

water

up to the condenser. The upper ground process is initiated when the hot

water

is accumulated in the condenser. Eventually, the boiled

water

transforms into steam that powers a turbine. As the turbine is loaded with steam, it will power the generator that

subsequently

produces electricity.
