Writing Feedback / IELT Task1: the various stages of using geothermal energy for electricity generation [4]

Geothermal energy used to produce electricity

The diagram illustrates that the various stages of using geothermal energy to produce electricity.

Overview, it is clear that there are 5 steps in the process, starting from flowing cold water underground and ending with making electricity from the energy in turbine.

At the beginning of the process, water in normal temperature passes into underground via a pipe. Second, there are two wells of input and output in the geothermal zone. Therefore, the water enters in the injection well and leaves in the production well. Third, the water becomes hot and comes back to the ground again.

At the fourth stage of the process, the condenser lets hot water evaporated, making it into steam. Later, the steam becomes the energy of the turbine. Then, the turbine conduces the energy into generator and provides a stable source of energy in generator. Finally, the electricity is manufactured by the generator and delivered into the tower.
