What you want to ask is whether the monthly average wind speed can be used to calculate the monthly power generation? cannot.
According to the query on Baidu Question Bank website, the monthly average wind speed cannot be used to calculate the monthly power generation, because the energy of the wind is proportional to the cube of the wind speed, and the ability of the wind turbine to capture the wind follows Bates’ law. Each model has a fixed wind speed power curve, and the wind energy density or the number of hours at full load wind speed can be used to estimate the power generation.
