People think of wind as an energy source with few limits, offering an unending power source with distinct capacity advantages over sources that deplete, such as fossil fuel.

Yet, new research in mesoscale atmospheric modeling by UNC Charlotte's Amanda S. Adams and Harvard University's David W. Keith, published in the journal Environmental Research Letters, suggests that the power capacity of large-scale wind farms may have been significantly overestimated.
