Benefits of wind:
1. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce. For example, the most common example is that dandelion seeds are spread by wind.
2. Wind energy is a widely distributed and inexhaustible energy source. Using wind energy to generate electricity reduces the use of fossil energy and protects the environment.
3. Wind plays an important role in improving farmland environment in agriculture. The flow of air forms wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air, creating conditions for the growth of crops.
Wind power generation, sailing boats sailing with wind power, bringing rainfall, flying kites, regulating the climate, transmitting pollen, wind-blown objects creating landscapes, windmills, etc.

Benefits of wind:
1. Moderate wind speed plays an important role in improving farmland environmental conditions. Near-surface heat exchange, farmland evapotranspiration, and transport processes of carbon dioxide and oxygen in the air accelerate or intensify as wind speed increases.
2. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce. The prevailing monsoon in China is beneficial to crop growth.
3. In Inner Mongolia Plateau, Northeast Plateau, Southeast Coast and inland mountains, there are abundant wind energy resources that can be developed and utilized as energy.
4. Wind energy is a source of clean energy. Wind energy installations have become more advanced, mass production has reduced costs, and in the right locations, wind power is now less expensive than other generators.
5. Wind causes air flow to bring precipitation and snowfall, and regulates atmospheric temperature.
What is wind energy used for?
Wind turbines are electrical equipment that convert wind energy into mechanical work. The mechanical work drives the rotor to rotate, and finally outputs alternating current. The working principle of the wind turbine is relatively simple. The wind wheel rotates under the action of wind. The kinetic energy of the wind is converted into the mechanical energy of the wind rotor shaft, and the generator rotates under the driving of the wind rotor shaft to generate electricity. It can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
1. Making food: Wind can accelerate the loss of water, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.
2. Blow dry clothes: Wind can accelerate the evaporation of water on clothes, speed up water loss, and make clothes dry faster.
3. Wind energy generation and irrigation: The wind can drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to prompt the generator to generate electricity. Wind power is pollution-free, clean energy, and renewable. Ancient people also used windmills to water crops.
4. Help fruit trees and crops bloomFlowers and fruits: Wind can blow away pollen, fertilizing fruit trees and crops to bloom and bear fruit.
5. Power-assisted sailing ship: In ancient times, ships without a power system relied on wind energy to move, which greatly reduced the voyage time.
6. The wind will blow away the dark clouds and haze: When the dark clouds block the sun, it is the wind that drives them away, allowing the sun to fill the earth again. When pollution is serious in winter, it can blow away the smog.
7. In the hot summer, the wind brings us coolness and drives away mosquitoes and flies.
8. Bring rainfall: Wind can blow clouds, promote the exchange of dry, cold and warm and moist air, and adjust the temperature and humidity of the air. This is what the ancients said: "The clouds turn into rain, and the dew turns into frost." Wind can send clouds and rain to distant places, completing the water cycle on the earth. In summer, warm and moist air blowing from the ocean brings abundant rainfall.

Wind is also a "double-edged sword". It can both Helping people will have a negative impact on people's lives.
It can spread pathogens and spread plant diseases; high-altitude winds are the meteorological conditions for locusts and other pests to migrate long distances; strong winds can cause mechanical scratches on leaves, lodging of crops, broken trees, and falling flowers and fruits, affecting yields. ; Strong winds also cause soil erosion, sand dune movement, and damage to farmland. In addition, wind has greater dangers. Blind reclamation in arid areas will lead to land desertification; strong winds and snowstorms in pastoral areas can scatter livestock and aggravate frost damage; some special properties of local winds often cause wind damage; salt-laden wind blowing from the sea Sea tidal winds, high-temperature and low-temperature foehn winds, and hot and dry winds all seriously affect the flowering and fruit setting of fruit trees and the grain filling of cereal crops.
In order to reduce the damage caused by wind, some measures can be taken to prevent wind damage. For example, wind-resistant varieties that are dwarf, lodging-resistant, and friction-resistant are often cultivated. In addition, building windbreaks and setting up wind barriers are even more effective methods of wind protection.
