Band 6.0 Sample: The diagram below shows how geothermal energy is used to produce electricity.
Paraphrasing Statement:
The given diagram illustrates how electricity in produce by geothermal power plant.
Overall Statement:
Overall it is clearly seen that, there are total five stages by which electricity is produced. It starts with pumping down of cold water and ends with supply of electricity.
Body Paragraph 1:
On coming to details, to start geothermal power plant. Firstly, cold water is pumped down into the earth where the injection well is located. The length of the injections well is 4.5km. Then by passing through injection well, the cold water gets to the geothermal zone. The geothermal zone contains natural hot rocks. The geothermal zone plays a significant role in the geothermal plant. In geothermal zone, cold water is turned into hot water. This hot water then sent to the production well.
Body Paragraph 2:
On moving further, on reaching the production well the hot water is pumped up. This hot water then reaches to container like box known as condenser. Here the hot water get condensed and is converted into steam. Then further this steam reaches generation turbine. The generator turbine first powered by the steam. The powered turbine convert the mechanical energy to electrical energy. At least this produces electricity further distributed through strong cable wires.
