A study by a research team from Harvard University in the United States shows that wind power does not have any negative impact on the environment as people imagine. First of all, wind power stations with a diameter of 100 meters will have a negative impact on migrating birds. It poses a direct threat to life. Thousands of birds die on wind turbines every year. In addition, when the separation generator reaches a certain density, it will also affect the hot and cold airflow in the atmosphere, causing direct changes in the local climate. .
In the atmosphere, the hot air balloon is in the upper layer and the cold air is in the lower layer. The wind power station will bring the hot air balloon to the ground, causing the ground to quickly heat up. The temperature rise can even reach 1.4℃. In fact, if you If you live in an area near wind turbines, you may be susceptible to this change. When you stand under rows of instantaneous separation generators, you will feel a significant increase in temperature. According to estimates by experts from Harvard University, if all energy supply in the United States adopts wind power, the average temperature in the United States will be at least will rise by at least 0.25℃.
However, Harvard University’s research seems to provide more reasons for restarting the development of coal resources in the United States. Currently, wind turbines in the United States only account for 6.5% of the total energy. It is unrealistic to use partial power generation. In addition, the partial power generation only changes the air flow, and it is temporary and regional, while the global warming caused by burning fossil energy is permanent, global and even irreversible, so so far, wind energy is still a Clean energy worth promoting.
In meteorology, the airflow is preheated, and the rising airflow becomes colder and sinks, so the cold air is below and the hot airflow is above, but the generator blades that are hundreds of meters high bring the hot airflow down to the ground. heat up. The effect of one wind turbine is not obvious, but when you are under a row of wind turbine arrays with a depth of more than 10 kilometers, the feeling must be very strong. The measuring instrument shows that the temperature at night will be 1℃ higher, but this The temperature increase is short-lived and recoverable.
