The kinetic energy stored in the wind can be found according to Bournoulli's equation:
<span class="texhtml">''K''''E'' '''<b> = 1 / 2(''m'' * ''v''<sup>2</sup>)</b></span>
<br>
This can be simplified as follows:
<span class="texhtml">''K''''E'' '''<b> = 1 / 8(ρ * π * ''D''<sup>2</sup>) * ''v''<sup>3</sup> * ''t''</b></span>

In order to benefit from the energy generating potential of wind turbines, it is important to understand how much wind is available at a given location. A Beaufort scale provides an indication of wind speeds based on various visual clues. While these clues offer indications of the wind speed on the ground, there is likely a greater amount of energy in the wind as the altitude increases. This is based on the boundary layer that develops on the Earth's surface as a result of various obstructions on the ground. The Beaufort scale is provided below:
