The diagram below shows how geothermal energy is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The picture illustrates the production of electricity from geothermal energy. Overall, there are 5 main stages in the process, beginning with collecting cold water. In order to generate electricity, the water is heated to produce steam which spins the turbine.
In the first stage, cold water is collected and pumped down with the help of an underground pipe. As the water is about 4,5 km deep under the ground, it goes through a geothermal zone after passing through the injection well. Then, the water is heated due to being surrounded by hot rocks
After that, it reaches the production well where it gets pumped up to a condenser on the ground. In this stage, the hot water is condensed and hence converted into steam. Finally, as the steam enters a generator turbine, it moves the turbine and therefore powers the generator. As a result, electricity is produced and ready to be distributed.
