Disadvantages of Vertical Wind Turbines

Some of the main disadvantages are:

• They produce less energy than horizontal wind     turbines, have lower efficiency rates, limited scalability, more     turbulence, and higher costs.
• They require a higher wind speed to start rotating,     which means they may not work well in low-wind areas.
• They are more prone to fatigue and stress due to the     varying torque on the blades.
• They may pose a threat to birds and bats that fly     close to the ground.
