The amount of power a wind turbine can produce is determined by four main factors: The amount of power a wind turbine can produce is determined by four main factors: The size of the wind turbine: This is directly proportional to the amount of kinetic energy from wind that can be converted into electrical energy. Wind speed: Higher winds allow for more significant power generation and lead to higher cost-efficiency ratios and less stability in overall production. Turbine efficiency: A more efficient turbine will convert more kinetic energy into electrical energy than an inefficient one. However, too much efficiency reduces stability and causes increased costs. Type of turbine (horizontal axis versus vertical axis): Horizontal axis turbines are often cheaper than vertical axis ones due to their design simplicity; however, they require more space, reduce axial loading on bearings which decreases life span, and are less suited for high winds since blades spin horizontally faster than vertically mounted ones do vertically mounted ones rotate slower, so they don't catch as much wind per rotation
