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.
Energy can be produced by using an Input Source such as Wind, Water or Wave. Wind Energy has been widely used since the 1980s and is evident by the increase in the number of Windmills across the world. Lately, Researchers have shown that a Wave-energy Machine can be three times more effective than a Wind Energy Machine. At first glance, the design of the wave energy machine may appear complex however the description of its inner workings detailed below will help a Reader understand it better.
As the name suggests, Wave Energy Machines depend on Wave as its Input Source. With the wave energy machine installed in the seabed, the wave direction is taken into consideration. As the water levels rise, the chambers located in the Wave-energy machine push the airflow upwards. Through the Air Duct located at the top, further air is pushed towards the Turbines. This increased airflow pressure causes the Turbines to rotate. The rotating turbines generate electricity which is in turn passed through the top Chamber to the Output Source.
The Location of the Wave Energy Machine plays a significant role in the amount of Energy that is produced. Larger waves produce high output whereas small waves produce low Output. It might seem obvious to then install Wave-energy machines in areas where there are large waves. An important point to consider however, is that Wave-Energy Machine Installation in areas with high waves incur high installation costs. So selecting suitable locations for Installation needs a thorough cost-benefit analysis upfront.
To conclude, a Wave-Energy Machine Installed at Suitable Locations and designed well can be extremely beneficial in generating high energy.
I will have to deviate from my usual point-by-point analysis for this essay. It is virtually mistake-free as far as I can tell, but there are two things worth noting.
First and foremost, the introductory paragraph is unneccessarily long and it includes something that shouldn’t be there – so-called ‘analysing’ on writer’s part. You shouldn’t add any information that is not directly related to the chart/diagram you’re writing about. In this particular case I would keep the last sentence and add another one before it.
The second issue is Capitalised Words. There is no need to capitalise ANY of the words in this text. This includes parts of the diagram too!
Overall, this writing is spotless both grammatically and lexically. It is well-structured and the contents are one hundred percent relevant to the task. Well done!
