This one shows a typical profile of lower wind during mid day.

This one shows pretty constant wind speeds over the ocean.

Of course, all of these are at an altitude that suits windmills and is different from the surface speeds.

When all cars are BEVs, it will result in a 20% increase in total electrical generation from today\'s levels.
More than 95% of BEV charging is done at night, during the slack time of electrical demand. This 95+% will not require any additional generation or transmission capability. The remaining <5% of 20% or <1% of charging will be at peak time. So the existing grid will need to grow by 1% to accommodate charging that will happen at
peak time.
I think we can manage that.
While the cars are recharged at night, where are all the solar
generators going to get the sun light to power them ?
Does the wind blow at night like it does in the daytime ? That I do not
know.
In general, no. Excluding weather fronts thermal heating is responsible
for a lot of air motion. This is particularly noticeable in the desert.
The wind picks up when the sun rises and usually calms down after
sunset. If you don\'t like sand in your hamburgers grill after dark.
