The diagram below shows how geothermal energy is used to produce electricity

The above illustration demonstrates the process of generating electricity from geothermal energy.
Overall, it is clear that this procedure has 5 steps until it could be used to produce power in generators of turbines.
In the first stage, cold water is used and pumped down to 4.5 kilometer below the ground. Next stage which is called the injection well, water is warmed up by located hot rocks under the surface. Afterwards, warmed water is pumped up to the ground in this stage which is mentioned as the production well.
Subsequently, hot water is formed to vapor by condenser and converted to steam which is utilized in turbines in the final stage. Finally, the created power by turbines is moved to generator in order to complete the whole plant. This portion is used energy from turbines to produce electricity in the fifth stage so it could be useful for large scale.
