That reminds me of that recent finding that wind turbines would be a few percent more efficient if they turned anti clock-wise (at least on the northern hemisphere), but practically turbines in use today turn clock-wise. Sure, it should not be to much engineering to change that but still you need to adopt the entire manifacturing process to it.

Would you have a source for this? Really curious what might cause that.

I can't vouch for the sources, but here is some reading material:

Interesting, so it's not the rotation direction of any individual turbine that matters but how the wake of turbines affect others around it.
