What can wind do?

Introduction What can wind do? 1. Spread plant pollen 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.

What can wind do?

1. Spreading plant pollen

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 power generation

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. Improving the farmland environment

Wind plays an important role in improving the farmland environment in the agricultural squadron. The flow of air forms wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Create conditions for the growth of crops.

Utilization forms of wind energy

The main form of wind energy utilization is to convert the kinetic energy of atmospheric movement into other forms of energy. Wind is horizontally moving air. The movement of air is mainly caused by the different intensity of solar radiation received by various latitudes on the earth.

In the equator and low latitudes, the sun's altitude angle is large, the sunshine duration is long, the solar radiation intensity is strong, the ground and the atmosphere receive more heat, and the temperature is higher; in high latitudes, the sun's altitude angle is small, and the sunshine is The time is short, the ground and atmosphere receive little heat, and the temperature is low. This temperature difference between high latitudes and low latitudes forms an air pressure gradient between north and south China, causing the air to move horizontally.

What do people use wind power to do in daily life

1. Wind is a natural energy source that can promote the exchange of dry, cold and warm and moist air. . A long time ago, humans learned to make windmills and use wind power to blow them to pump water and process food. Now people also use windmills to generate electricity.

2. Wind can mix and balance a wide range of heat and water vapor, adjust the temperature and humidity of the air; it can send clouds and rain to distant places, completing the water cycle on the earth.

3. Wind plays an important role in improving farmland environment in agriculture. We know that air flows to form wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Create conditions for the growth of crops.

4. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce.

5. However, wind often brings disasters to humans. Storms, typhoons, and hurricanes can flood farmland, collapse houses, and interrupt water and electricity. Tornadoes can destroy large areas of buildings, leaving a mess in their wake.

6. Moreover, the wind will also bring up sand and dust, forming sandstorms, which is harmful to the human body. It will also drive the desert to move and form deserts.

1. Wind lift:

Wind lift has been widely used since ancient times.

2. Wind power generation:

Wind power generation usually has three operating modes:

p>

(1) It is an independent operation mode. Usually a small generator provides power to one or several households. It uses a battery to store energy to ensure power 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 power to a unit, a village or an island.

(3) Wind power generation is integrated into the conventional power grid to provide power to the large power 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 assist navigation:

In the development of today's motor boats, 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 heat energy in household energy is increasing, especially in high latitudes in Europe and North America. Drinking water is a major energy consumer. In order to solve the heat energy needs of households and low-level industries, wind heating has been greatly developed.

Wind energy advantages and disadvantages

1. Advantages

Wind is a clean energy source. 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. Wind energy facilities are mostly non-three-dimensional facilities that can protect the land and ecology. Wind power is a renewable energy source that is environmentally friendly and clean. Wind power is energy-saving and environmentally friendly.

2. Disadvantages

The ecological problem of wind power is that it may disturb birds. For example, the grouse in Kansas, USA, have gradually disappeared after the emergence of windmills. The current solution is offshore power generation, which is more expensive but also more efficient.

In some areas, the economics of wind power generation are insufficient, and the wind in many areas is intermittent. What is worse is that in places such as Taiwan, there is less wind in summer and during the day when power demand is high. time; 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 some open space to build.

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