Example
You should spend about 20 minutes on the task.
Scientists and engineers are continuing to look for new ways to generate electricity. The following is a diagram of how electricity may be generated from tidal flow.
Write a report for a university lecturer that describes the diagram.
You should write at least 150 words.
The Diagram shows the features and the process of hydro electric project.
Overall, this plan produces electricity by using the energy of water flow at the point of using the water-flow at the estuary .
The project consists of certain structure and components. The most evident feature of this plan is the main barrage structure which separates the inland bay or estuary from the sea. On top of this there is a roadway and under it there is a water tunnel connecting the inland bay or estuary and the sea. Also under the main barrage structure, electricity generator is set. Last but not the least, there are some sluice gates at the inner side of the main barrage structure and these gates control the flow of water.
In the sea, water lever rises and falls based on high tide and low tide. When there is a low tide in the sea, water level in the inland bay or estuary remains higher than that of the sea. At that moment, sluice gates are opened and water flows from inland bay to the sea through the water tunnel. The low of water causes the turbine of generator to spin and this creates electricity.
In summary we can say the plant produces electricity by using a renewable energy source which is environment friendly. But, it is an inefficient process as it is dependent on tidal changes, which have a slow cycle.
