​​​​​​​Warming could foil wind energy

Global warming could alter the way air moves around the world, ultimately affecting one of the most popular means of generating clean energy: wind turbines.

Kristopher Karnauskas and his colleagues at the University of Colorado Boulder used ten global climate models to explore how winds might change in two warming scenarios. Their results suggest that, in both low- and high-emissions scenarios, wind resources will decrease across the northern mid-latitudes, mainly as a result of weather patterns associated with accelerated warming in the Arctic. In the Southern Hemisphere, high emissions see wind resources increase on average, because of temperature differentials over land and sea. The effects vary by location, however.
