1. Lower Noise Levels. One of the key advantages of vertical axis wind turbines is their reduced noise output compared to horizontal axis wind turbines (HAWTs). HAWTs can produce significant noise due to the high-speed rotation of their blades. In contrast, VAWTs operate at lower rotational speeds, resulting in quieter operation.
