Which regions in China are most suitable for wind power generation and what should the wind speed be

At the junction of Inner Mongolia, cut-off (high wind speed at wind stop) is 19-25 m/s. What matters is not the wind speed, but the number of standard hours in a year. The so-called standard hours refer to the wind speed at full power of the wind turbine, which is generally. 11-15 m/s. It can reach 2,000 standard hours per year, which corresponds to the wind speed. It is an area rich in resources. As for the wind direction, it is best that it does not change much throughout the year. it doesn't matter if it changes a lot, because the wind turbine can automatically adapt to the wind
