 Kinetic Energy in Wind  Electrical Energy

 Available Kinetic Energy = ½ mV 2  Available Kinetic Power = ½ pAV 3 ◦ p = Density = 1.23 kg/m 3 ◦ A = Area Swept by blades  Radius of blade = 4.25 m ◦ V = 11 m/s  Calculate Kinetic Power of Wind Turbine  46,449 Watts

 Find Actual Output of Wind Turbine at 11 m/s  (Approximate) 12,324 W

 Calculate Efficiency of Power Conversion of Wind Turbine  Eff = 12,324 / 46,449  Eff = 26.5%
