The amount of power, and therefore electricity, a wind turbine can produce is largely based on wind velocity using this equation: Power = ½ ρAV 3 ρ = air density; ~1 kg m^3 A = swept area (π r^2 ) V = velocity (m s-1) Power is measured in Watts Larger wind turbine = more power Higher wind speed = lots more power
