The provided illustration highlights the process by which electricity is produced through a geothermal energy. Overall, what stands out from the diagram is that the process consists of five steps, starting from pumping down cold water into the geothermal zone and culminating in producing electricity from the generator which powered by turbine.
In the first step, cold water is injected through the injection well and travels to a depth of 4.5 km into the geothermal zone with hot rocks. Then, the water heats up and transforms into hot water, which is subsequently pumped up through the production well. After that, it enters the production well and then pumped up into condenser.
The last step, once the hot water has been pumped up in the condenser, the steams is produced. In the following stage, steam passes into the turbine, which is powered through it. Finally, the generator, which is powered by turbine, produces electricity where it is then transferred into lines.
