What can wind do for humans?

Wind can help people do the following things:

1. Prepare food: Wind can accelerate water loss, such as air-dried meat, air-dried fruit pulp, etc. Xinjiang raisins are a typical dried food.

2. Drying clothes: Wind can accelerate the evaporation of water on clothes, accelerate water loss, and speed up drying of clothes.

3. Wind power generation and irrigation: The wind can turn the blades of the windmill, and then increase the rotation speed through the increase in speed to prompt the generator to produce electricity. Wind energy is a non-polluting, clean and renewable energy. Ancient people also used windmills to water crops.

4. Help fruit trees and crops bloom and bear fruit: the wind can carry away pollen, fertilizing fruit trees and cropsltures so that they flower and bear fruit.

5. Electrically Assisted Sailing Ship: In ancient times, ships without electrical systems relied on wind power to move, which greatly reduced the duration of the voyage.

6. The wind will drive away the dark clouds and mist: When the dark clouds block the sun, it is the wind that blows them away, allowing the sun to fill the earth again. When pollution is heavy in winter, it can make smog disappear.

7. During the hot summer, the wind brings us coolness and drives away mosquitoes and flies.

8. Bringing rain: The wind can blow the clouds, promote the exchange of dry, cold and warm and humid air, and adjust the air temperature and humidity. This is what the ancients said: "The clouds turn into rain, and the dew turns into frost." The wind can send clouds and rain towards de remote places, thus completing the water cycle on Earth. In summer, warm, humid air coming from the ocean brings abundant precipitation.

Wind is also a “double-edged sword”. It can not only help people, but also harm people as well. Life has a negative impact.

It can spread pathogens and spread plant diseases; high-altitude winds are the weather conditions that allow locusts and other pests to migrate long distances; Strong winds can cause mechanical scratching of leaves, lodging of crops, broken trees, and falling flowers and fruits, affecting yields. Strong winds also cause soil erosion, shifting sand dunes and damage to agricultural land. Additionally, wind poses greater dangers. Indiscriminate reclamation of drylands will lead to land desertification; strong winds and snowstorms in pastoral areas can disperse livestock and worsen frost damage; some special properties of local winds often cause damage by wind blowing from the sea. Maritime tidal winds are high; -High and low temperature foehn winds as well as hot and dry winds all seriously affect the flowering and fruit set of fruit trees as well as the grain filling of cereal crops.

In order to reduce wind damage, certain measures can be taken to prevent wind damage. For example, dwarf, lodging-resistant and scrub-resistant varieties are often grown. In addition, the construction of windbreaks and the installation of barriers againste wind constitute even more effective methods of protection against wind.

Besides generating electricity, what else can wind energy be used for?

1. Lifting water by wind:

Lifting by wind power has been widely used since ancient times.

2. Wind power generation:

Wind power generation generally has three modes of operation:

(1) It is an independent mode of operation, usually a small generator. 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 is combined with other electricity generation methods (such as diesel engine electricity generation) to provide electricity to a unit, a village or aisland.

(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. Wind heating:

With the improvement of people's living standards, the demand for thermal energy for household 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 energy is a clean energy source. Wind installations have become more advanced, mass production has reduced costs, and in the right places, wind power is now cheaper than other generators. Wind turbine installations are mostly non-three-dimensional installations that can protect land and ecology. Wind energy is a renewable, clean and environmentally friendly energy source. 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 is to produce electricityat sea, 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 relatively large amounts of energy.

When wind power is generated, the wind turbine will make a lot of noise, so it is necessary to find open spaces to build.

Current wind production is not yet mature and there is still considerable room for development.

What is the role of wind energy

Wind can cause precipitation and snowfall. It can also adjust the temperature difference in the atmosphere and propagate rising warm air currents from the equatorial region towards the poles. from the northwest wind, plants in desert areas, such as buttergrass, tamarisk, Haloxylon ammodendron, camel thorn, etc., tilt toward the southeast to facilitate the identification of directions.

The functions of wind are approximately as follows:

1. Wind causes air flow and causes precipitation and snowfall.

2. Large-scale airflow causes the movement of ocean currents to balance the heat distribution of seawater.

3. Adjust the temperature difference in the atmosphere and distribute rising warm air currents from the equatorial region towards the poles.

4. Pollination and reproduction of wind-pollinated plants.

5. Wind energy production.

6. Air purification and diffusion of polluted air.

The above is just my personal opinion. for reference!
