The wind is a natural phenomenon on the earth, which is caused by the heat of solar radiation. The sun shines on the surface of the earth, where the heat is different from the surface of the earth, and the temperature is poor, causing the convective movement of the atmosphere to form wind. It is estimated that only about 2% of the earth's solar energy is converted to wind energy, but its total is still very impressive. The world's wind energy is about 2.74X109MW, which can be used for wind 2X107MW, than the earth can develop and use the total amount of water can be 10 times larger.
Wind energy is a huge potential for the development of non-polluting renewable energy, especially for coastal islands, remote mountainous areas, sparsely grassland pastures, as well as away from the grid and the recent power grid is also difficult to reach the rural frontier, as a solution to production And a reliable way of living energy, has a very important significance. Even in developed countries, efficient and clean winds are gaining increasing attention.
