Agree that this is effectively arguing semantics, and it is taking energy from the wind. But the effect of each _is_ very small. There are definitely farms with >100 turbines close together. This one has >600 and has long runs of them close together. https://en.m.wikipedia.org/wiki/Alta_Wind_Energy_Center

while that one produces more electricity, this one has about twice as many turbines in close proximity: https://en.m.wikipedia.org/wiki/San_Gorgonio_Pass_wind_farm
