Windpower to shift southward: Karnauskas et al. find that windpower in the northern hemisphere will decrease, and may increase in the South, that central US windpowere will decrease in winter and all kinds of interesting things.

"Some of the projected regional changes in wind power noted above have a strong seasonal dependence, while others are manifest throughout the year (Supplementary Fig. 7). For example, the projected decreases in the central US, Japan and the horn of Africa occur primarily during boreal winter, the projected increases in eastern Brazil, Madagascar and the southern Arabian Peninsula are much stronger during austral winter, and the projected increases in southern mainland Africa and Southeast Asia are relatively constant throughout the year.
When integrated zonally (along lines of latitude; Fig. 3), a clear and asymmetric dependence on emissions scenario emerges. The total decrease in power across the northern mid-latitudes (30–65° N) is largely insensitive to emissions scenario. In contrast, the total increase across the southern tropical/subtropical band (10–30° S) only emerges under the RCP8.5 scenario. Thus, in a globally integrated sense, the decrease in the Northern Hemisphere is partially balanced by an increase in the Southern Hemisphere, but only under the high greenhouse gas emissions scenario."
They attribute the decrease in the North as caused by decreasing pole to equator temperature difference and increase in the south dues to land-sea warming gradients. I attach fig 3.
