The diagram shows how geothermal energy is used to produce electricity.


Sample Answer 1

Band 7+


The figure depicts the phases involved in geothermal energy generation. The procedure starts with the delivery of cold water and concludes with power distribution.


To begin with, cold water gathered in a tank is pumped down into an injection well located at a depth of 4.5 kilometres. The geothermal zone, located under the earth's surface, heats the water by transferring heat from hot rocks. Following that, the hot water is pushed up via the production well. When this hot water reaches the condenser located above ground, it changes into steam. To increase the pressure of this steam, it is allowed to escape via a tiny tube. This steam rapidly rotates the turbine, where mechanical energy is converted to electrical energy. In turn, the turbine powers a generator that produces electricity to be sent along power lines.


To summarize, the stages involved in creating electricity are: heating the water with hot stones, transporting it to the condenser, and lastly putting it in the generator to produce power.

Sample Answer 2

Band 6.5

The picture illustrates how electricity is produced by geothermal energy. Overall, the procedure consists of 5 stages, beginning with the injection of cold water and ending up with the generator which is powered by a turbine.

At the beginning of the process, cold water is pumped down into the injection well which is 4.5 km deep. After that, the water passes through a geothermal zone which comprises hot rocks. Following this, the water collects in the production well from where hot water is pumped up in the form of steam.

At the fourth stage in the process, the condenser is used to store steam which is produced from the production well. Subsequently, the steam which is stored in the condenser is supplied to the turbine, as the turbine works with the help of steam. Then, the turbine starts rotating, and its rotation helps the generator to start. Finally, the generator produces electricity which is supplied over an area.

Sample Answer 3

Band 5.5

The picture below describes how electricity is produced in a geothermal power project.

Overall, the process consists of five stages, beginning with the cold-water pumping and ending with the production of steam in both the generator and the turbine.

At the beginning of the process, chilled water is pumped beneath 4.5km from the earth's surface to the injection well. As soon as the water reaches the geothermal zone, where the rocks are at a boiling temperature, it is pumped up into the well, where hot water production occurs.

In the fourth stage, steam is formed in the condenser. Afterwards, it is sent to the turbine to move speedily, so that it generates power. The last step takes place in the enormous generator powered by the turbine and finally begins to produce electricity before passing it to the tower.
