[IELTS Writing Task 1] Descriptive essay/report about wave-energy machine

Task 1
You should spend about 20 minutes on this task.

The diagrams below show the design for a wave-energy machine and its location.

Summarise the information by selecting and reporting the main features and make comparisons where relevant.
You should write at least 150 words.

The diagrams illustrate the interior design of a wave-energy machine along with the possible locations to install the machine.

The wave first travels into the lower chamber of the machine, which causes the water level to rise and creates an upward air flow that turns the turbine above the chamber. At the same time, the other turbine is caused to spin due to the atmospheric air from outside flowing into the upper chamber. This process generates energy using the speed of the turbines caused by the different air flows.

While the mechanism of the machine is comparable from machine to machine, the location of each machine correlates with the amount of energy generated as well as the costs involved. The nearer the machine is to mainland, the lower the output, with the best energy generators being far away from land. Coincidentally, machines with lower output also requires lower costs to install.

Overall, the wave-energy machine utilises wave energy to generate electricity. The location of installation, however, creates a difference in administrative costs and output level.

How many diagrams? What are the differences between the diagrams? Where are these machines installed? What is the general trend for the function of the machine? Avoiding an immediate representation of the general trend, then the proper usage of the machines, based on its source of power should have been stated in the summary overview.

Identify the image that you are discussing in every paragraph. Since this is a 3 paragraph essay, the next 2 paragraphs should be represented by topic sentences that identify the wave energy machine and its possible location. That indicator helps to create a better idea as to the method of energy generation within the paragraph. You have to make sure that you have a separate paragraph for the 2 possible locations. There needs to be a difference in the explanation presented based on the location and type of wave. Therefore, the essay requires a 4 paragraph presentation for:

Par. 1: Summary + Trending statement
Par. 2: Function of the machine
Par. 3: Machine moving in high wave position
Par. 4: Machine moving in low wave position.

While both are energy machines, there is a difference in the way the waves produce energy and how much it will cost. So you will need to consider both in relation to the way the machine functions. Try to use more analysis in the presentation. That is a requirement for the task 1 essay. Study the diagram for at least 5 minutes, while drafting your essay. Make sure there is a thorough analysis of the presentation for accuracy and differentiation purposes.
