Question

which of these is a major disadvantage of wind energy? the production of electricity from wind turbines causes too much air pollution. no technology exists for capturing wind efficiently. wind turbines are cheap to build. wind does not blow consistently in all areas of the earth.

Explanation:

Wind energy is a renewable energy source. Wind turbines do not cause air pollution as they do not burn fuel. There are technologies like modern wind turbines that can capture wind efficiently. Wind turbines being cheap to build is an advantage, not a disadvantage. However, wind is an intermittent resource. In many areas, the wind does not blow consistently. This inconsistency means that wind - powered electricity generation is not always reliable without energy storage or backup power sources.

Answer:

Wind does not blow consistently in all areas of the earth.
