Blowing Hot Air. Wind Farms And Global Warming

by Editor

In a new study published in Nature scientific journal, found that wind farms in Texas made air temperature go up almost 1 C. Texas, along with China has the most wind turbines in the world. Texas has 4 of the world’s largest wind farms. China, presently is manufacturing up to 36 wind turbines every day.

Texas Has 4 Of The World's Largest Wind Farms

Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools.

But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature.

Satellite data over a large area in Texas, that is now covered by four of the world’s largest wind farms, found that over a decade the local temperature went up by almost 1C as more turbines are built.

This could have long term effects on wildlife living in the immediate areas of larger wind farms.

It could also affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.

It is reported China is now erecting 36 wind turbines every day and Texas is the largest producer of wind power in the US.

Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York, who led the study, said further research is needed into the affect of the new technology on the wider environment.

“Wind energy is among the world’s fastest growing sources of energy. The US wind industry has experienced a remarkably rapid expansion of capacity in recent years,” he said. “While converting wind’s kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.”

The study, published in Nature, found a “significant warming trend” of up to 0.72C (1.37F) per decade, particularly at night-time, over wind farms relative to near-by non-wind-farm regions.

What do you think about these findings? Are you alarmed by the results? Do you even trust the results of the study? What are your thoughts on China’s investment in green energy? Is this an indication that they are taking global warming seriously? Which country do you think has the most wind and should have more wind farms? For me countries like Ireland and Scotland come to mind.
