The flow chart illustrates the various stages in the production of electricity from geothermal energy.
The process witnesses five steps overall. As can be seen, first of all, cold water is pumped down from a tank connected with the ground to the injection well underground with the depth of 4.5 kilometers. After that, it passes through the so-called geothermal zone where there are hot rocks used to heat the water. The hot water is subsequently piped to the production well.
Following that, it is pumped up to the condenser installed on the ground, which converts hot water into steam. At the next stage of the process, the steam, moving in a circular movement, is applied to drive turbine, which powers generator to produce electricity. Energy is transmitted to an energy tower finally.
To summarize, the geothermal power plant is harnessed to generate electricity through two distinct stages: heating cold water with hot rocks and converting hot water into steam to power turbine. It is noteworthy that the former stage occurs underground, while the latter happened on the ground.
