1. Wind power was stopped because its environmental damage far outweighed its economic benefits and was not environmentally friendly. The dangers are: 2. Wind power generation will harm the local ecological environment, destroy vegetation, change the terrain, and cause soil erosion and desertification. 3. Electromagnetic radiation generated by wind power affects human habitation. In wind energy systems, generators, substations and transmission lines are the main sources of electromagnetic radiation. Additional receivers in wind power plants, when receiving signals, will pick up the electromagnetic wave signals reflected from the wind turbine blades. The reflected signal is a delayed signal that has a great impact on AM radio systems. 4. Wind energy affects the local climate. Wind energyis the use of wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of heat will inevitably produce or consume another type of energy. Therefore, the energy production process of wind turbines will inevitably consume part of the wind energy in the atmosphere. one of the important factors of climate change, wind energy will inevitably lead to climate change. 5. Wind turbine blades are prone to safety accidents. When wind turbine blades are subjected to strong winds of more than 25 m/s, the bending moment, torque, shear resistance and extrusion resistance that the blade roots can withstand are limited. In severe cases, the entire blade will fly. and causing injury to personnel and damage to buildings on roads. 6. Noise risks linked to wind energy production. For a fanator of such a scale, noise is inevitable when the blades spin with huge party costs. Fan blade noise can be roughly divided into three categories: Thickness noise, which is caused by the compression of the air and the blades. On windy days, with doors and windows closed, do you often hear high-pitched and harsh sounds, which sound like ghosts and wolves howling, coupled with the dark sky outside, it's a little scary to thinking about it, as the name suggests; suggests, is caused by the heavy load on the blades; impulse noise, that is to say when the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.
Which photovoltaic or wind energy is least harmful to the environment?
The presence of radiation can cause ionization and cause cancer.
Ionization occurs when electrons arent expelled from their electron shell by ionizing radiation, which makes the atoms positively charged. Since cells are made of atoms, ionization can cause cancer. A cell is made up of approximately billions of atoms. The likelihood of ionizing radiation causing cancer depends on the radiation dose rate and the body's susceptibility to receiving the radiation.
Terrestrial satellite communications stations, large power plants, energy transmission and transformation equipment, high and ultra-high voltage transmission lines, subway trains and trains Electrics, as well as most household appliances, can generate various shapes and frequencies. , sources of electromagnetic radiation of different strengths.
Detailed information:
1. Electromagnetic waves are composed of electric fields and magnetic fields that oscillate in phase and are perpendicular to each other. They move in the form of waves in space, and their direction of propagation is perpendicular to the plane formed by the electric fields and the magnetic fields. Effectively transfers energy and momentum.
2.Radar systems, television, mobile phone and radio transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various treatment equipment electric, subway trains and electric trains, as well as most household appliances can produce various forms and different electromagnetic radiation. sources of different frequencies and intensities.
3. Electromagnetic radiation fills space, is colorless, odorless andinvisible and can penetrate many materials, including the human body. If the human body is exposed to a radiation dose that exceeds safety for a long time, cells will be damaged or killed over a large area.

Photovoltaic and wind energy are both currently recognized as new sources of clean energy with little impact on the environment. 'environment.
However, even if it is claimed that it is clean energy strictly speaking, whether it is photovoltaic or wind energy, it will have a certain impact on the environment .
For example, photovoltaics will have the following impacts on the environment:
1. Installing photovoltaic panels will take up a lot of space.
2. During the production process of photovoltaic panels, trichlorosilane and silicon tetrachloride will be produced, which are substances that aret an impact on the environment and human health.
For example, wind energy will also have an impact on the environment during the deployment process.
It is said that large-scale deployment of wind power will affect atmospheric circulation and cause changes in ambient temperature.
It is also said that the large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of precipitation areas.
Even if the above statement is accurate, the two new energy sources of photovoltaic power and wind power themselves have not yet achieved 100% impact on the environment. ...it will have some impact to some extent.
Of course, compared to traditional energy sources, photovoltaic and wind energy have very little impact on the environment and are sufficiently respecteduse of the environment. This is why these two new sources of energy and other new sources of energy have such advantages. extensive development.
