As fossil fuel is running out, wind power is considered as an effective alternate energy source. The professor of the listening mainly discusses that wind power source is a very useful and beneficial source to get electricity, while the author of the reading thinks that it isn't really practical.
The first point brought out from the reading is that wind power is not efficient and predictable. It states that wind power is so unstable that using wind power as an energy source is not very beneficial. The lecturer, however, claims that wind power could be utilized with other sources such as solar power. The professor mentions that although wind power source is quite unstable, it can be complemented by utilizing it properly with other methods. She gave an instance of Sweden, where solar and wind force is combined properly, to support his opinion.
Another argument given by the passage is that the cost of wind power is uneconomical. It is insisted in the reading material that the efficiency of wind force is too insignificant in spite of its high cost. On the other hand, The listening material explains that generating electricity from wind power is economically valuable. She insists that using wind power source is very cost-efficient, because it is pollution free and doesn't require large space. According to the listening, wind power is more economical than any other energy sources.
The reading material insists that wind turbines kill a large number of birds. It demonstrates that at least one hundred birds are killed by turbines every month all over the world. The professor argues that the problem is solved by building and relocating new turbines. The lecturer explains that 80% of birds' deaths reduced by relocating turbines or replacing them with new and taller ones. She also explains that it is also possible to install warning devices which can expel birds from turbines. Whereas the reading passage states that the wind power is not very valuable and useful, the professor strongly insists that the wind power has many practical uses and its problems can be covered with other methods. |
