London, April 30 - Wind farms can cause climate change, according to a study, that shows how the technology is already pushing up temperatures, The Telegraph reported Monday.
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 1 degrees Centigrade as more turbines are built.
This could have long term effects on wildlife living in the immediate areas of larger wind farms, the newspaper noted. It could also affect regional weather patterns as warmer areas affect the formation of cloud and even wind speeds.
