Clean energy - wind energy
Overview of wind energy: the use of land or sea wind energy to operate turbines.
Advantages of wind energy: rich usage experience, development of mature industry and infrastructure, unlimited renewable resources and flexible project scale. An intermittent resource, ineffective in all areas, interferes with radar signals, is noisy and looks bad. Wind power currently accounts for around 1% of the world's electricity supply. The cost of onshore electricity production is lower than that of offshore production. The high cost of energy storage is a major obstacle. The cost is lower, from 7 to 14 cents/kWh.

What harm do wind turbines do to the human body?
The presence of radiation can cause ionizedon and can cause cancer.
Ionization occurs when electrons are knocked out of their electron shell by ionizing radiation, making 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.
Indetailed training:
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 electrical processing equipment, subway trains and electric trains, and most of household appliances. household appliances, etc. These are all sources of electromagnetic radiation that can produce various shapes, different frequencies and differentes 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 to a radiation dose that exceeds safety for a long time, cells will be damaged or killed over a large area.

Wind energy will harm the environment, climate andnoise pollution, as follows:>
1. Wind energy production will harm the local ecological environment, for example by destroying vegetation, changing topography, causing soil erosion and land desertification.
2. Wind energy affects the local climate. Wind energy uses wind energy present in the atmosphere. According to the law of conservation of energy, the consumption and production of a type of energy must produce or consumeWed another type of energy. Therefore, wind turbines process of electricity production.inevitable.
3. The environment around the wind farm is good, so it will become a paradise for many birds, but a large number of birds will be injured by the wind turbines.
