1. Wind power generation will harm the local ecological environment, such as destroying vegetation, changing topography, causing soil erosion and desertification of the land.
2. Wind power generation 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 energy must generate or consume another type of energy. Therefore, the power generation process of wind turbines must consume a part of the atmosphere. As one of the important factors of climate change, wind energy will inevitably bring about climate change.
3. The surrounding environment of 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 injured by wind turbines.
4. Noise hazards of wind power generation.
In fact, wind turbines will indeed cause a lot of unavoidable harm in the operation process, but the utilization and development of any kind of energy will bring certain harm to nature more or less.
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 a local area, it will not change from the macro environment and the macro climate. From an angle, the degree of harm is far less than the harm caused by the burning of fossil energy.
As for bird damage, according to a 2009 study, wind farms produce about 0.3 bird deaths for every 1 gwh of electricity produced. But fossil fuels are more harmful to birds. Statistics show that fossil fuels cause 5.2 bird deaths per 1 gwh, which is dozens of times more than wind power generation.
For noise pollution, the vast majority of wind turbines generally choose plains and grasslands in remote and sparsely populated areas, or the peaks of peaks that are rarely inhabited, or even in uninhabitable areas. In the shallow sea area, compared with land, the development space of offshore wind power generation system is almost unlimited, which can save a lot of land resources; the wind shear is small, which can effectively reduce the tower height of the unit, and the construction cost of offshore wind power is lower; offshore wind energy resources are far away It is more abundant than land, the wind speed is higher, and the power generation is also significantly improved; at the same time, the sea level friction is small, the load acting on the unit is small, and the service life of the unit can be as long as 50 years; noise, birds, landscape and electromagnetic interference The impact of other problems on offshore wind power is relatively small; it basically has no impact on the ecological environment, and it is green and environmentally friendly.
