? Wind power can produce renewable energy, but it may also cause noise pollution and harm the health of nearby residents. Faced with growing public doubts, Health Canada decided to launch a comprehensive study and set up a team of experts to investigate the relationship between low-frequency noise from wind power and human health. Canadian Health Minister Leona Aglukkaq announced that Ottawa will lead the study in response to concerns from residents near wind farms. Canada will spend $1.8 million to form a team of more than 25 acoustic and medical experts, including four international consultants, to investigate the situation of 2,000 residences living near 8 to 12 wind turbines.
Residents were forced to hide in basements to sleep
“Currently, there is not enough evidence to prove the relationship between the noise from wind turbines and the adverse effects on human health, but Health Canada and some scientific literature have indeed documented some nuisance issues caused by wind power generation in communities," the ministry said in a statement. However, Sherri Lange, CEO of the North American Platform Against Wind Power, claimed that the low-frequency noise and vibrations produced by wind turbines can cause sleep disorders, headaches, depression, anxiety and even blood pressure problems."The house vibrated like a guitar resonance," Lange
said residents were forced to flee into basements to sleep or sleep in the courtyard. As far as she knows, 40 families in Ontario have left wind farms because of this . There are currently 140 wind farms equipped with wind turbines across Canada, most of which are located in Ontario and Quebec.

How far away is wind power from being inhabitable
Wind power There is no radiation from the generator to humans.
Wind turbines convert wind energy into mechanical work. The mechanical work drives the rotor to rotate and ultimately outputs alternating current electricity.equipment. Wind turbines generally consist of components such as a wind wheel, a generator, a diverter, a tower, a speed limiting safety mechanism, and an energy storage device.
The working principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to generate electricity. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
Features:
The power of wind power is entirely determined by the power of the wind turbine. It is always tempting to buy a larger wind turbine, but this is not correct. The current wind turbine only charges the battery, and the battery stores the electrical energy. The amount of electrical power people ultimately use is more closely related to the size of the battery. The size of the power mainly depends on the size of the air volume, not just the size of the machine head power.
In the Mainland, small wind turbines are more suitable than large ones. Because it is more easily driven by small winds to generate electricity, continuous small winds can provide greater energy than temporary strong winds.
When there is no wind, people can still use the electricity brought by the wind normally. That is to say, a 200W wind turbine can also be used with a large battery and an inverter to obtain 500W or even 1000W or even more. Big power out.

It depends on the situation. A single wind turbine should be at least 200m away from residential areas, and for large wind farms, this minimum distance should be no less than 500 meters to prevent the human body from being affected by electromagnetic wave radiation from wind power. Converting the kinetic energy of the wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, 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.
