The world needs a new source of energy, an unspillable source.

Does anyone know what is the relationship between the blade angle and the power generated for a wind turbine?

Does anyone know what is the relationship between the blade angle (angle of attack) and the power generated for a wind turbine? Is there a formula for it? All I know is P=(1/2)(“rou”)(A)(V^3)(CP), but it do not have the blade angle factor in it….thx alot
