Wind power plants are changing the climate of Inner Mongolia?

Hong Kong "South China Morning Post" November 25 article, the original title: wind power plants are changing the climate? In pastures 12 kilometers north of the Huitengliang Wind Power Plant in Xilinhaote, Inner Mongolia, the herdsman Sichenbattle found a strange phenomenon that even meteorologists were puzzled. “The temperature on the ground rises quickly, just like a hot pot on the stove. The wind blows like a headless fly, and a drop of rain does not fall,” he said during the rainy season in August. He pointed to the rotating blades of the wind turbine on the horizon and said: "This phenomenon has occurred since they came."

This is not merely derived from the superstition of a herdsman or his disgust with modern technology. Local government statistics are also consistent with Sichenbatter’s statement. Engineer Li Qinghai of the Xilin Gol League responsible for precipitation statistics said that the precipitation data collected by them indicate that the amount of precipitation around wind farms has decreased significantly since 2005, and even some areas have reduced by 80%.

Scientists conducting related research have concluded that the large-scale use of wind energy will lead to local and global climate change due to wind energy and wind direction changes, ie wind energy is not completely green.

As China may become the world's largest wind power producer by the end of this year, scholars in China and around the world have called on the wind power industry and government to take this issue seriously. They warned that the construction of more wind power plants could lead to unexpected disasters without further understanding of the impact of wind farms on local and global climate systems.

Gao Hu, deputy director of the National Development and Reform Commission's Renewable Energy Development Center, said that the government has never heard of this issue. However, there is still such a possibility in theory. A team led by David Keith, a professor at the University of Calgary in Canada, found that "the use of wind power in large quantities will have a significant impact on the continental climate." Keith said that local observation in Inner Mongolia is very interesting and worthwhile to be funded by the government. However, due to the large number of factors affecting the climate, it is difficult to determine exactly the specific effects of each factor.

Prof. Hu Yongyun (Peking University) of Peking University believes that as long as the scale of wind power plants is small, wind turbines are unlikely to significantly affect local climate such as precipitation, but large-scale wind power plants are different. He said: “Before such large-scale bases are built, wind power companies and governments have the responsibility to explain to the public their possible impact on the climate.”

Tezlav, head of the Meteorological Association of the University of Leipzig, Germany, warned that herders found that the increase in surface temperature made him doubt the length of their observations. "It takes 20 or 50 years of observation to verify this statement," he said. "As far as I understand it, the development of large-scale wind power plants will be no more than five years."
