Which statement about wind energy is true?

• A. It is always available everywhere with equal efficiency
• B. It requires no land area
• C. It depends on local wind availability
• D. It produces significant pollution

Answer: (C)

The main idea is that wind energy output depends on local wind availability. A turbine only generates electricity when wind is blowing, and how much power it produces changes with wind speed and how often the wind occurs at that site. Because power increases with higher wind speeds, locations with steady, strong winds make more electricity than calm or highly variable sites. This means wind energy isn’t available everywhere with the same efficiency—wind conditions vary by place, time of day, and season. The other statements aren’t accurate: wind farms do require land or sea area for the turbines and infrastructure, and while operation is clean, there are some emissions tied to manufacturing and installation, so it isn’t pollution-free.
