You know how wind-generated electricity was supposed to be 'greener' than the regularly-generated stuff, and would help to 'save the planet', and all those good things? Not so fast. The Telegraph reports:
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.
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.
. . .
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.

So a much-hyped technology that was supposed to help stave off global warming is instead contributing to it, at least on a local scale! All those birds are dying for no good reason! For a brief, delirious moment, I thought I could actually hear environmentalists weeping, and wailing, and gnashing their teeth. Isn't the irony too delicious for words?
