Academic IELTS Writing Task 1: how to answer a diagram on hydroelectric power generation and supply; with discussion, analysis of the picture; tips & model answer

This IELTS Writing post focuses on a discussion on a diagram on hydroelectric power generation and supply. This is a post-on-demand from some candidates who find writing answer to the diagram very confusing to answer. I’ve included a short discussion/ analysis on the picture and written a short sample answer for you. You’ll also find some tips to answer the question effectively. Writing an answer to a diagram is quite easy if you are careful to analyze the picture and to use proper connecting devices / linking devices. 

Let’s have a look at the question title and the picture.

You should spend around 20 minutes on this task.

The diagram shows how hydro-electric power is generated and supplied to different places.

Summarise the information by selecting and reporting the main features.

Write at least 150 words.

Tips for answering this diagram:

  1. When answering a process diagram, the first thing you should do is to mark the diagram and take some notes with your pencil. This will make your plan to write the answer easily.
  2. When writing, be careful about your paragraphing. You do not need 4 or 5 paragraphs; only 3 paragraphs will do. Here is a writing structure that you can follow:
1st paragraph Introductory sentence + picture summary
2nd paragraph 1st part of the picture (movement of water)
3rd paragraph 2nd part of the picture (generation and supply of electricity)

 

  1. Remember to use some linking devices to describe the diagram so that the writing flows smoothly.
  2. Revise your answer once you finish writing; this will give you the advantage of finding your mistakes and correct them which is essential to improve your score.

Now, let’s have a look at the model answer that I’ve prepared for this picture.

Model answer:

The diagram illustrates the process of producing electrical power using water. Overall, the process involves several stages that initiates with the evaporation of seawater and culminates in supplying electricity to different locations.

The process commences when seawater evaporates to form a small cloud as the effect of solar heat. Once the cloud produces rainfall in the land area, some of the water is collected in a reservoir linked with a dam and pipelines. In the subsequent stages, the valve of the dam is released that causes a large amount of water flow to the turbine section below the reservoir. Here, the turbine rotates to produce the electrical current. Passing through the turbine, the water is pumped back to the reservoir and this process continues as a cycle.

The electricity produced in the turbine section is transferred to the transformer station through high voltage cables. Afterward, the station, which is responsible for the delivery, supplies the produced electric current to houses/apartments, nuclear plants, and hospitals/schools through underground cables.
