In this set of issues, both the reading passage and the lecturer discuss several aspects of the wave-energy facilities known as wave farms. To be specific, according to the reading passage, they have some advantages. In contrast, the lecturer insists that this optimistic perspective is just illusion, and contradicts this argument for following three reasons. To begin with, the professor argues that power generators of wave farms are not reliable and have several technical problems. To be specific, since they are new technologies, so their converters are often malfunctioned, and cause fluctuation. As a result, the power generators are often broken down. This explanation refutes the argument of the reading passage that wave energy can be produced by reliable power generator. Moreover, the lecturer asserts that convertors of wave farms have also harmful chemicals like lubricant. These materials can cause damage to ocean environment. Furthermore, if they were leaked, they could affect adversely to marin organisms since are toxic. This assertion casts doubt on the reading passage’s opinion that wave farms are environmentally friendly. Finally, the speaker claims that wave farms can make negative affects on the surrounding landscape. This is because floating convertors are highly visible due to their bright color. Therefore, it might be easily detectable. Moreover, they are usually set up closed to shores, so they can be discovered by people like tourists. This claim counters the reading passage’s idea that wave farms are not noticeable well, and do not spoil the natural beauty. In conclusion, the speaker challenges the explanation from the reading passage on account of the reasons stated above, and stress the disadvantages from the wave farms. |
