Which of the following is considered a drawback to using wind energy as a source of power?
wind energy is highly polluting. wind energy is nonrenewable. winds do not always blow consistently. winds produce lesser quality energy than other sources.

Option (3)

Explanation:

Wind energy is directly derived from the wind. In the places where wind blowing is quite frequent, there wind mills are being set up, and the turbines in it rotates due to the prevailing wind. Due to this continuous motion of turbines, it collects the wind energy and it is being transferred into electrical energy.

It is cost-effective and does not produce any kind of pollution and is completely a renewable energy, that it can generated again and again.

It does have certain drawbacks also, because the area may sometime do not experience constant wind, due to which it cannot store energy. So frequent wind blowing areas are the best place to set up windmills.

Thus, the correct answer is option (3)

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
