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.
The presence of radiation can cause ionization and cause cancer.
Ionization occurs when electrons are knocked out of their electron shell by ionizing radiation, causing atoms to cpositively 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.

Main sources and effects of radiation:
< p>1. Electromagnetic waves are composed of electric fields and fieldsmagnetic which oscillate in phase and are perpendicular to each other. They move in the form of waves in space. Their direction of propagation is perpendicular to the plane formed by the electric and magnetic fields. Fields, efficiently transferring 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 electrical processing equipment, subway trains, electric trains and most Household appliances can produce sources of electromagnetic radiation of various shapes, frequencies and intensities.
3. Electromagnetic radiation fills space, is colorless, odorless and invisible and can penetrate many materials, including the human body. If the human body is exposed for a long time to a dose of radiation depensuring security, cells will be damaged or killed over a large area.
