The total wind power flowing into the turbine is defined by the fairly simple wind power formula, shown to the right. The power into the turbine blads is a function of the wind speed to the 3rd power V times V times V, air density, and swept area of the turbine blades. A simple version of the wind power formula is shown to the right.

At standard conditions, the power in 1 m2 of wind with a speed of 5 ms is 0.64753 81 W. The power in the same 1 m2 of area when the wind speed is 10 ms is 647 W. This illustrates two basic features of wind power. One is that wind power is rather diuse. It requires a substantial area of wind turbine to capture a signicant amount of.
