This diagram illustrates the production of electricity which is done by utilizing the geothermal energy.
Overall, the geothermal zone act as the converter, which changed the cold water into hot water. The steam produced by the hot water favours the turbine that helps the generator to produce electricity.
Initially, cold water flowed down upto 4. 5 km where it reaches the injection well. Here comes the critical phase, water cross over the hot rocks as it named as geothermal zone. Liquid reaches the production well with high temperature, in that case steam produced and grouped in condenser. From there, it passed to turbine to run which gives the sufficient amount of power to generator to generate electricity.
The tunnel of both cold and hot water had the similar range of 4. 5 km, on the contrary, geothermal zone covers the huge space then others. On one hand, Steam helped the turbine to work, on other hand, turbine processed the energy to make generator run.
