These data provide annual average wind power density in watts per one square meter of a turbine sweep area. Average speeds in the table are based on the so-called Rayleigh speed distribution and are given for the sea level. To get the same density above sea level, the air speed has to increase by 3% per 1000 metre (1% per 1000 ft) elevation.
