Perhaps, but wind power also tends to peak at night.
- nradov 5y agoWind speeds near the ground peak in the early afternoon. Higher altitude winds peak at night, but you need quite a large turbine to catch those. Sometimes there's no wind for days at a time. https://journals.ametsoc.org/view/journals/clim/27/11/jcli-d-13-00286.1.xml https://journals.ametsoc.org/view/journals/clim/27/11/jcli-d...
- jhgb 5y agoQuoting from your link: "It is found that daily extreme wind speeds at 10 m are most likely in the early afternoon, whereas those at 200 m are most likely in between midnight and sunrise" Ground is irrelevant; there's a reason why wind turbines are being put on top of tall towers.

- Gwypaas 5y agoAlmost, the hub is still a bit more than 50m below but the rotor points above. Modern off-shore ones are true monsters. For example this one, rotor diameter 220m, highest point 248m. https://www.ge.com/renewableenergy/wind-energy/offshore-wind/haliade-x-offshore-turbine https://www.ge.com/renewableenergy/wind-energy/offshore-wind...
