Multiple choice

What is the primary source of noise pollution from wind turbines?

  1. The rotation of the blades.

  2. The generator.

  3. The transformer.

  4. The transmission lines.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary source of noise pollution from wind turbines is the rotation of the blades. The noise is caused by the interaction of the blades with the air, and it can be a nuisance to nearby residents.

Multiple choice
