6.5 Power and energy from wind turbines
The power output of a wind turbine varies with wind speed. Every turbine has a characteristic wind speed–power curve, often simply called the power curve, shown in Figure 9.
The energy a wind turbine will produce depends on both its wind speed–power curve shown in Figure 9 and the wind speed frequency distribution shown in figure 10 at the site.
Using the data from these graphs enables us to calculate a wind energy distribution graph, which you’ll examine next.
