Ecological impact, climate environment.
In terms of ecological impact, the birds in nature are undoubtedly the most seriously harmed. According to data, with the development of wind power, hundreds of thousands of birds die every year under the impellers of wind turbines. In the eyes of us humans, the three fan blades on each wind turbine are just necessary to absorb wind power; but in the eyes of birds, each fan blade is like a guillotine, ruthlessly harvesting their lives.
In addition to the ecological impact, another impact is the impact of the climate environment. This view mainly comes from the fact that when wind power is generated, the fan blades will drive the conversion of high-temperature air in the upper layer and low-temperature air in the lower layer, thereby enhancing the greenhouse effect. However, scientists compared the temperatures and found that the change before and after was about 0.5°C. There are still many unknown factors in this change, and it is unreasonable to attribute all causes to wind power generation. Of course, some people look at this matter from the perspective of the law of energy conservation, believing that wind power takes up wind energy in the air. So originally these wind energy should have other uses, but were suddenly cut off or changed artificially, which would also have an impact on the natural environment.
It destroys the local ecological environment, destroys vegetation, electromagnetic radiation affects residence, consumes wind energy, affects climate change, produces noise hazards, and corrosion and cracks on the blade surface can easily cause blade breakage and cause accidents.
Wind power generation will harm the local ecological environment, such as destroying vegetation, changing the topography, causing soil erosion and desertification. The electromagnetic radiation produced by wind power affects human habitation. An alternating electromagnetic radiation field is formed around high-voltage transmission lines and affects human health.
Wind power affects local climate. Wind power uses wind energy in the atmosphere. The power generation process of wind turbines consumes part of the wind energy in the atmosphere and brings about climate changes.
