They have long been championed as a way to combat global warming by creating clean energy.
But wind farms can actually alter the climate according to a new study by a group of American scientists.
The team from the University of Illinois found that daytime temperatures around wind farms can fall by as much as 4C, while at night temperatures can increase.
The study found that currently the effect is restricted to areas near to the turbines, but the increase in larger farms could create weather changes on a regional scale.
The study was led by Somnath Roy, assistant professor of atmospheric sciences at the university, with the San Gorgonio wind farm in California the focal point of his research. Read More
