I visited Zhangbei’s power generation windmill during the summer vacation
Wind power stations are actually known to everyone as “big windmills”. A motor is installed in the windmill. When the desert wind blows, it will push the blades on the wind power station (so these blades must be both light and strong) to rotate, providing heat to the motor, and then converting the heat. This is the entire process of wind power generation. But building this wind power station also requires certain skills. The blades of the windmill cannot be too heavy, otherwise the wind may not be able to push the windmill. At the same time, the blades need to be very strong, otherwise the sand mixed with the wind in the desert It will definitely break the leaves. At the same time, the part below the wind power station must also be very strong, because we all know that the power of sandstorms is very huge. If the wind power station is not built well, it is likely to be blown away by the sandstorm.
So, we must not only discover energy, but also protect energy and create a beautiful "global village" with our hands!
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 and landforms cause soil erosion and desertification of the land.
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.
