Week Ten

Your first task is to read the text below and decide if the
statements are (T) true or (F) false. Please check your reading comprehension answers in QUIZ 10.1. Have you identified the same expression of contrast as listed in the following activity?

Sun or Wind

One of the biggest advantages of solar and wind energy is the fact that the energy is free of cost. This production of energy also does not cause any pollution. However, pollution is produced when windmills, solar collectors or other associated equipment are manufactured. Wind and solar power plants are suitable for remote areas where it ́s too expensive to extend the electricity power grid.

As for the area needed to build the power plants, solar power plants need very large areas and storage space for large batteries. A wind turbine, despite its height, takes up only a small plot of land, which can then still be used for agriculture. Even though the size of the land taken seems to be an advantage, very large wind farms are needed to provide communities with electricity.

Before making decisions, the costs have to be considered as well. Although solar collectors, panels, and cells are expensive to manufacture, solar and power are said to be infinite. However, it is not suitable for countries with unstable climates. People living near wind farms often complain about the noise generated by wind turbines. Each turbine can generate the same level of noise as a family car travelling at 70 mph.

Decide if the statements are (T) true or (F) false.
1) Solar energy is more expensive than wind power. T x F
2) Windmills produce a lot of pollution. T x F
3) Solar power plants take up only a small piece of land. T x F
4) Batteries used in solar power plants do not have to be stored. T x F
5) Wind turbines generate more noise than a car travelling at 70 mph. T x F
