What is wind energy

Wind is a natural phenomenon on the earth. It is caused by the radiant heat of the sun. When the sun shines on the surface of the earth, the surface of the earth is heated differently, resulting in a temperature difference, which causes the convective movement of the atmosphere to form wind. It is estimated that although only about 2% of the solar energy reaching the earth is converted into wind energy, the total amount is still very considerable. The global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW, which is 10 times larger than the total amount of water energy that can be exploited and utilized on the earth.

The history of human use of wind energy can be traced back to the BC, but the development of wind energy technology has been slow for thousands of years and has not attracted enough attention from people. However, since the world's oil crisis in 1973, under the dual pressure of conventional energy crisis and deterioration of the global ecological environment, wind energy has re-emerged as a part of new energy. Wind energy has great potential for development as a new energy source that is pollution-free and renewable, especially in remote mountain areas with inaccessible coastal islands, sparsely populated grassland ranches, and rural areas that are far from the power grid and that are difficult to reach in the near future. Frontiers, as a reliable way to solve production and living energy, has a very important significance. Even in developed countries, wind energy is increasingly valued as an efficient and clean new energy source.
