This study estimates that all the human beings will be able to sustain only by the total amount of the natural energies as solar, wind, and/or hydro-power, at the end of this 21st century. At that time, the total population in all over the world should increase up to 13 billion. As the 1st step, this paper estimates the overall potential of the wind power in all over the world. The surface of the earth is divided into around 380000 square meshes according to the technique called N-code developed by T. Nishioka, and the geographical feature factors are calculated for these meshes. The concept of this feature factor is fundamentally based on the statistical correlation between the wind velocity and the geographical features, and this method was also adopted by the "Green Energy" Project developed by our Ministry of Agriculture, Forestry and Fisheries in 1978〜1988. It is shown that the geographical feature factors give well correlation between the wind velocities and the distances from the sea and also the land ratio. At the beginning of coming 22nd century, if we would assume population of all over the world to be 13 billion, we figured out that the wind turbines could provide 7.7% of total energy demand which would by consumed on the earth at the beginning of the 22nd century.
