Does wind power affect the global environment? American scientists: exacerbating the trend of global warming

We all believe that wind power is an energy-saving and environmentally friendly way of generating electricity. After all, wind power does not produce any substances that pollute the environment at all, unlike oil and minerals. The way resources generate electricity is very different, but people's deep-rooted thinking is likely to be overturned by American scientists!

A scientist from Harvard University in the United States said that if humans want to use the resources on the earth to generate another resource, it is impossible to be completely energy-saving and environmentally friendly, and wind power is one of them. First, its impact on the environment is insignificant and will not be as easily felt as the harm of plastic products. So how does wind power affect the earth's environment? Let’s take a look at what this American scientist said!

Although the main energy source of wind power generation is wind, and wind is almost readily available on the earth, many scientists have even decided to convert all non-environmentally friendly power generation methods into wind power generation. However, American scientists say that enabling large-scale wind power generation will occupy more earth resources, such as space, and there will be more open space on the earth for wind power generation, although it seems to be much more economical than fossil energy. resources, but there are many shortcomings of wind power generation. One of them is the occupation of land. Space with a radius of one thousand or even ten thousand meters cannot be lived in normally. Secondly, the most important thing is that scientists believe that wind power generation will affect The climate on the earth will intensify the trend of global warming!

Said that many large-scale wind power plants will change the direction of air flow for a long time, which will cause the heat in the atmosphere to continue to dissipate, causing the moisture in the air to evaporate quickly. This will prevent the earth's temperature from being effectively stored. In order to maintain the original temperature, the earth will absorb more heat. In this way, the global climate will become warmer and warmer. Although fossil energy will be saved, However, there is not much difference in the impact on the environment. Therefore, American scientists believe that wind power is not the best way to generate electricity, and using solar energy to generate electricity is a way to truly curb global warming, save energy and protect the environment!

The principle of wind power generation is to use wind power to drive the rotation of windmill blades, and then increase the speed of rotation through a speed increaser to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of approximately three meters per second.

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to generate electricity. The machine generates electricity; it consists of a nose, a rotor, a tail, and blades. The functions of each part are: the blades are used to receive wind power and convert it into electrical energy through the nose; the tail keeps the blades always facing the incoming wind.direction to obtain maximum wind energy; the swivel allows the nose to rotate flexibly to realize the function of adjusting the direction of the tail; the rotor of the nose is a permanent magnet, and the stator winding cuts magnetic lines of force to generate electrical energy.

Due to the unstable air volume, the wind turbine outputs alternating current of 13 to 25V, which must be rectified by the charger and then the battery is charged, so that the electrical energy generated by the wind turbine becomes chemical energy. . Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.

Advantages

1. Wind energy is a clean energy source.

2. Wind energy facilities are improving day by day, and mass production reduces costs. In appropriate locations, the cost of wind power generation is lower than that of other generators.

3. Wind energy facilities are mostly non-three-dimensional facilities that can protect the land and ecology.

4. Wind power is a renewable energy source, very environmentally friendly and very clean.

5. Wind power is energy-saving and environmentally friendly.

Disadvantages

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

2. In some areas, the economics of wind power generation are insufficient: wind power in many areas is intermittent. What is worse is that in places such as Taiwan, in summer and during the day when power demand is high, wind power is Less time; must wait for energy storage technologies such as compressed air to develop.

3. Wind power generation requires a large amount of land to build wind farms to produce relatively large amounts of energy.

4. When wind power is generated, the wind turbine will make huge noise, so it is necessary to find some open places to build.

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

6. The wind speed is unstable and the amount of energy generated is unstable;

7. The utilization of wind energy is seriously restricted by geographical location.
