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 flow chart illustrates the process through which geothermal energy is used to produce electricity in a special area.

Overall

, it is obvious the process consists of 5 main steps, from the land surface to underground facilities and back to the surface layer.

To begin

with, the reservoir which stores cold water releases the low-temperature fluid down through a pie, length of about 4.5 km, to the injection well. Following that, in order to heat the icy water, it flows past a hot rock, which is known as the Geothermal zone, and is fully heated up before arriving at the production well.

Subsequently

, a thermally treated stream is pumped up and

then

appears in the condenser overground, where the high-temperature water chillings again.

According to

the diagram, to produce electricity, the generator turbine starts to spin with the help of cold flow passing through, which in turn drives the generator to move on and produce electrical power. The energy

then

will be conveyed to the rest of the region through electrical wires.
