WebWind Energy and Power Calculations. Print. The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3. Power = Watts. ρ (rho, a Greek letter) … WebThe universal standard to assess the performance of a wind turbine is a plot of the Power Coefficient versus the Tip Speed Ratio performance curve. This curve tells you how efficiently a turbine converts the energy in the wind to electricity. Various methods were used to plot this curve. The results are show in Figure 7 below.
