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 diagram illustrates the processes involved in the production of
electricity
from geothermal energy and water
.
Overall
, it is a fairly simple process to understand which consists of five separate stages in the process of electricity
production from geothermal power. The cold water
is heated to produce steam
. This
steam
is then
used to power the generator which in turn produces electricity
.
In the first stage of the process, cold water
travels down a 4.5-kilometer-long pipe into an injection well. After that, the water
goes through an area called the geothermal zone below the Earth’s surface, which contains a lot of hot rocks used to increase the temperature of the water
.
At the next step, the hot is transferred into another well called the production well where it is pumped up to a condenser, ready for the next step. In the condenser, the water
transforms into steam
and is used to power a turbine. The hot steam
rotates the turbine which powers the generator to produce electricity
. The resulting electricity
is contributed for different purposes via various grids.Submitted by khanhlinh892002 on
