11. Direction UPWIND DOWNWIND Give Lower Noise / Turbulence. No Tower Shadow on Blades, Thus Avoid Fatigue Loads on Blades. Naturally Yaws in the Wind Direction. Avoids Complicated and Costly Active Yaw.
12. Blades TWO THREE Cheaper, lighter, operates at high speeds leading to transmission costs, easier to install. Higher speed sop greater loading, thus more noise. Less cyclical load, dynamic or gyroscopic imbalance of 2 bladed WTGs with change in wind direction.
