Q. The diagrams depict the process of electricity production in two stages. Summarize the main features and write a report of at least 150 words.
The given diagrams illustrate a structure that is used to produce electricity from wave power.
The process consists of a structure mounted on the side of a cliff having a large chamber. A turbine is also fixed inside the column and is used to generate electricity in two stages. In the first stage, when a wave hits the equipment, water is forced to move to the chamber. Pressure is exerted on the air inside the column. This causes the turbine to move and the air passes into the atmosphere producing electricity.
Further, the next part reveals the second phase in which the waves move back. When the level of water goes down, the air from outside the column is sucked back by the turbines. Consequently, electricity generation continues. In this stage, the turbines only moves in one direction. It is not affected by the air flow.
Thus, it can be analyzed that it is a very helpful process to generate electricity in two stages.
REFERRAL POINTS:
Diagrams show/depict production of electricity // structure mounted on a different/sea wall // contains a large chamber // a turbine is fit into it // electricity is generated in two phases // wave forces water into the chamber // pressure is exerted on the air column // movement of turbines is caused // air passes out and produces electricity // wave moves back and level of water goes down // air from outside is sucked back // electricity keeps getting produced.
Vocabulary: Phases: stages // cliff: small mountain // production: generation // contains: consists // fit: installed // device: apparatus/equipment
