Question

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

Explanation:

• Analyze each option:
• "No technology exists..." is false as wind turbines (technology) capture wind.
• "Wind does not blow consistently..." is a disadvantage because inconsistent wind means unreliable energy production in some areas.
• "Wind turbines are cheap..." is an advantage, not a disadvantage.
• "Production causes too much air pollution" is false; wind energy is low - pollution.

Answer:

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