	Several different factors influence the potential wind resource in an area. The three main factors that influence power output are: '''wind speed''', '''air [[density]]''', and '''blade radius'''.<ref name=Ref3>European Wind Energy Association. (2013, Nov. 4).

	Wind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more [[power]] because stronger winds allow the blades to [[RPM\|rotate faster]].<ref name=Ref3/> Faster rotation translates to more [[mechanical power]] and more [[electric power to the grid\|electrical power]] from the [[generator]]. The relationship between wind speed and power for a typical wind turbine is shown in Figure 2.		Wind speed largely determines the amount of electricity generated by a turbine.

The relationship between wind speed and power for a typical wind turbine is shown in Figure 2.

	Turbines are designed to operate within a specific range of wind speeds. The limits of the range are known as the [[cut-in speed]] and [[cut-out speed]].<ref name=Ref4>D.

	The cut-in speed is the point at which the wind turbine is able to generate power. Between the cut-in speed and the rated speed, where the maximum output is reached, the power output will increase cubically with wind speed. For example, if wind speed doubles, the power output will increase 8 times. This cubic relationship is what makes wind speed such an important factor for wind power. This cubic dependence does cut out at the rated wind speed. This leads to the relatively flat part of the curve in Figure 2, so the cubic dependence is during the speeds below 15 [[meters per second\|m/s]] (54 kph).

	The cut-out speed is the point at which the turbine must be shut down to avoid damage to the equipment. The cut-in and cut-out speeds are related to the turbine design and size and are decided on prior to construction.<ref name=Ref5>Energy Research Unit (n.d.). (2013, Nov. 4).
