Four major hazards of wind power generation

The four major hazards of wind power generation are: noise hazard, damage to the landscape, interference to wildlife, and impact on local climate.

1. Noise hazard: In fact, wind turbines will indeed cause many unavoidable hazards during operation. However, for the utilization and development of any kind of energy, there may be many Either way it will cause some harm to nature.

2. Damage to the landscape: Because wind turbines are usually large and need to be built in open areas, they often destroy beautiful mountains, beaches, and farmland. This will not only affect the living environment of local residents, but also have a negative impact on the tourism industry. Many attractions have become difficult to appreciate due to the construction of wind turbines, and this is an issue that needs attention.

3. Interference with wild animals: The low-frequency noise and electromagnetic radiation of generators may disrupt the life and migration habits of sensitive animals. Some studies suggest that the operation of wind turbines can cause nearby wildlife to decline or migrate elsewhere in search of safe habitat.

4. Impact on 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 produce or consume another type of energy. Therefore, the power generation process of wind turbines must It is necessary to 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.

The working principle of wind power generation

Convert the kinetic energy of the wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy. This is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to windmill technology, power generation can begin at a breeze speed (the degree of breeze) of approximately three meters per second.

The devices required for wind power generation are called wind turbines. This kind of wind turbine can be roughly divided into three parts: wind wheel (including tail rudder), generator and tower. Large-scale wind power stations basically do not have tail rudders, and generally only small ones (including household types) have tail rudders.

The wind wheel is an important component that converts the kinetic energy of the wind into mechanical energy. It is composed of several blades. When the wind blows towards the blades, aerodynamic force is generated on the blades to drive the wind wheel to rotate. The blade material requires high strength and light weight, and is often made of fiberglass or other composite materials (such as carbon fiber).
