Writing Feedback / The process of making electricity from a geothermal power plant - Cambridge 12 Test 8 Task 1 [2]
The diagram below shows how geothermal energy is used to produce electricity.
Summarise the information by selecting and reporting the main features and make comparison where relevant.
"The picture demonstrates the process of making electricity from a geothermal power plant. In general, there are 3 significant steps to transform heat from the geothermal zone into electricity. First, in the injection well, cold water from a small tank is pumped through a 4.5-kilometer pipe down to the geothermal zone. Underground hot rocks in this area warm up the water. Next, In the production well, hot water is pushed into the condenser by using a hole, which has the same length as the pipe. As pumped up, the warmed water will produce steam that fills the consender and runs into the turbine over a small hole. In a specific room, there is a turbine and a generator. The turbine after being powered by steam will rotate and create centrifugal force. From there, the generator which links with the turbine derives its spin energy into electricity and transfers it to the high voltage power pole by transmission lines.
