Are low-wind conditions a socio-economic problem?

As a result, low winds – especially during prolonged periods known as ‘wind droughts’ – can have increasingly important socio-economic implications through reducing or inhibiting wind power generation. In this section, we explore the low-wind conditions that occurred over a large part of Europe during 2021. Figure 1a.

How does wind speed affect wind power generation?

Wind power generation is highly sensitive to variations in wind speed, as the power output from a wind turbine is proportional to the cube of the wind speed (for example, a 10% reduction in wind speed leads to a 27% reduction in power output). Furthermore, a minimum wind speed is required for turbines to start generating electricity .

How can the wind power industry overcome the challenges?
