The results of a recent study shows that the areas immediately surrounding wind farms have experienced a significant rise in temperature. This study will undoubtedly provide added fuel to the debate over wind energy as a green alternative to fossil fuels.
On the bright side, this article does claim that the impact of wind farms is much smaller than the estimated change caused by other factors such as man made global warming.
Wind farms can cause climate change, according to new research, that shows for the first time the new technology is already pushing up temperatures.
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.
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. The team studied satellite data showing land surface temperature in west-central Texas.
However Prof Zhou pointed out the most extreme changes were just at night and the overall changes may be smaller. <b>Also, it is much smaller than the estimated change caused by other factors such as man made global warming. </b>
