The adverse impacts of wind power generation on the environment are as follows:
1. Wind power generation will harm the local ecological environment, such as destroying vegetation, changing topography, causing Soil erosion turns the land into desert.
2. Wind power affects local climate. Wind power uses wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one kind of energy must produce or consume another kind of energy. Therefore, wind turbines The power generation process must consume part of the wind energy in the atmosphere. As one of the important factors of climate change, wind energy changes will inevitably bring about climate changes.
3. The environment around the wind farm is good, so it will become a paradise for many birds, but it will cause a large number of birds to be harmed by wind turbines.
4. Noise hazards from wind power generation.
In fact, wind turbines do cause a lot of unavoidable harm during operation. However, the utilization and development of any kind of energy will more or less cause certain harm to nature. harm.
For example, fossil energy coal and oil will produce a large amount of carbon dioxide and other harmful gases during combustion and cause a serious greenhouse effect. Even if wind power generation changes the microclimate, microenvironment and temperature of local areas, But from the perspective of the general environment and climate, the degree of harm is far less than the harm caused by the burning of fossil energy.
1. Wind energy was stopped because its harm to the environment was far greater than the economic benefits it produced, and it was even less environmentally friendly. The harms include:
2. Wind power generation will harm the local ecological environment, destroy vegetation, change the topography, cause soil erosion and desertify the land.
3. The electromagnetic radiation produced by wind power generation affects human habitation. In wind power generation systems, generators, substations, transmission lines, etc. are the main causes of electromagnetic radiation. When the receiving device attached to the wind power plant receives the signal, it will receive the electromagnetic wave signal reflected by the wind turbine blades. Reflected signals are lagging signals that can have a significant impact on AM radio systems.
4. Wind power affects local climate. Wind power uses wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of heat must produce or consume another type of energy. Therefore, the power generation process of wind turbines must consume part of the wind energy in the atmosphere, and wind energy is a climate change One of the important factors of change, its changes will inevitably bring about climate changes.
5. Wind energy blades are prone to safety accidents. When the wind turbine blades are subjected to strong winds of more than 25m/s, although the wind turbine is in a shutdown state, due to the bending moment and Torque, shear strength, and extrusion strength are limited. In severe cases, the entire blade may fly out, causing casualties and building damage on the road.
6. Noise hazards of wind power generation, volumeFor such a large wind turbine, when the huge long blades rotate, its noise is inevitable. The noise of wind blades can be roughly divided into three categories: thickness noise, which is produced by the compression of air and blades. In windy weather, when the doors and windows are closed, do you often hear a sharp and harsh sound, which feels like a ghost crying or a wolf howling? , coupled with the gloomy sky outside, it’s a bit scary to think about it; load noise, as the name suggests, is caused by the blades bearing a large load; impulse noise is generated when the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.
