Several theoretical studies have been reported in recent years which have indicated that large-scale wind
farms can have an impact on local and regional meteorology, possibly on climate. Now evidence of it
based on field observations has also begun to emerge. The present paper traces the evolution of this
knowledge. It discusses the theoretical studies on the possibility of wind turbines effecting climate
change, and summarizes the emerging confirmation of those predictions. The concluding part of the
paper assesses the implications of these findings in the context of the world's past experience on global
warming and its present thrust to meet substantial portions of its energy needs with renewables.
