The diagram illustrates the process of producing electricity using geothermal energy. Overall, the system involves five key stages, starting from pumping cold water underground to generating electricity with a turbine and generator.
Initially, cold water is injected 4.5 kilometers below the surface through an injection well. This water reaches the geothermal zone, where it comes into contact with hot rocks. The heat from the rocks warms the water, transforming it into hot water.
Next, the heated water is pumped back to the surface via the production well. Once above ground, the hot water releases steam, which drives a turbine. The turbine, powered by the steam, rotates and activates the generator, which produces electricity.
Finally, the steam is cooled down in a condenser, turning it back into water. This water can then be reused in the cycle, making the process sustainable.
This method of electricity generation effectively utilizes natural heat from the Earth, offering a renewable and environmentally friendly energy source.
