Wind farms |
The lecturer discusses the positive effects of the wind power, which casts doubt on the reading passage's claim that wind farms have diverse malfunctions. First, the lecturer describes that the effect of wind farms killing birds and bats is ignorable. On the other hand, other human activities are more harmful for those flying animals compared with wind farms. Besides, it is much environmentally friendly, so that it could save more animals by wind farms. And red light for warning airplane does not attract birds anymore, which is not dangerous for them. This directly refutes the reading passage's assertion that wind farms cause many birds and bats to kill. Second, it is silent than we expected, thanks to the development of the related technology; quiet blade design. Moreover, it looks gorgeous, not spoiling our landscape. This contradicts the reading passage's arguments that wind farms have trouble in noise and sight. Last, it is economical so that we can use it as an energy source efficiently. People have designed the wind farms taller and larger in terms of blade, which propels to produce more energy, being competitive. Thus, the cost invested in wind farms can be compensated within three months. This rebuts the reading passage's statement that wind farms are not a cost effective way as an alternate energy source. |
