1. Wind can generate electricity and bring comfort to people's lives.
2. The wind can bring coolness to people in summer.
3. Prepare food: Wind can accelerate water loss, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.
4. Wind can help plants pollinate and reproduce: Wind can spread pollen and plant seeds, helping plants pollinate and reproduce. The monsoon prevailing in China is beneficial for crop growth.

Causes of wind formation:
Wind is a phenomenon of air circulation on earth , usually caused by the sun. Caused by radiant heat. Sunlight shines on the surface of the earth, causingdue to an increase in surface temperature. The air on the surface expands under the influence of heat, becomes lighter and rises.
After the warm air rises, the cold, low-temperature air enters laterally. The rising air gradually cools and becomes heavier and becomes smaller. The higher surface temperature heats the air and causes it to rise. air is called wind. When the accumulated water vapor (cloud) condenses into water, its volume decreases and the surrounding water vapor reconstitutes it, forming wind.

1. Wind power to lift water:
Wind power to lift water. elevator water has been used since ancient times and is widely used.
2. Wind power generation:
Wind power generation generally has three modes of operation:
(1) It is an independent mode of operation, usually a littlegenerator. is used to produce electricity. One or more households provide electricity, which uses batteries to store energy to ensure energy consumption when there is no wind.
(2) Wind power generation is combined with other power generation methods (such as diesel engine power generation) to provide electricity to a unit, a village or an island.
(3) Wind energy production is integrated into the conventional electricity grid to supply the large electricity grid. Often, dozens or even hundreds of wind turbines are installed in a wind farm, which is the main development direction of wind power generation.
3. Sail to aid navigation:
In the development of today's motorboats, in order to save fuel and increase speed, ancient sails have been developed.
4. Heatwind power:
With the improvement of people's living standards, the demand for thermal energy for domestic energy is increasing, especially in the high latitudes of Europe and North America. Drinking water is a large consumer of energy. In order to meet the thermal energy needs of households and small-scale industries, wind heating has been considerably developed.

Advantages and disadvantages of wind energy
1. Advantages
Wind is a clean energy source. Wind energy installations have become more advanced, mass production has reduced costs, and in the right places, wind energy is now cheaper than other generators. Wind turbine installations are mostly non-three-dimensional installations that can protect land and ecology. Wind power is a renewable energy source, clean and environmentally friendly. Wind power is energy efficient and environmentally friendly.
2. Disadvantages
The ecological problem with wind power is that it can disturb birds. For example, grouse in Kansas, USA, gradually disappeared after the emergence of wind turbines. The current solution consists of producing electricity at sea, which is more expensive but also more efficient.
In some regions, the profitability of wind energy production is insufficient and the wind is intermittent in many regions. What's worse is that in places like Taiwan, there is less wind in summer and during the day. When energy demand is high, one must wait for the development of energy storage technologies such as compressed air.
Wind power generation requires a large amount of land to build wind farms to produce quanrelatively large amounts of energy.
When wind power is generated, the wind turbine will make a lot of noise, so it is necessary to find an open space to build.
Current wind production is not yet mature and there is still considerable room for development.
