I concur that wind is useless, but...actually...wind is worse than useless. 

If wind were "just" useless, the world wouldn't see the massive increases in total power costs in those societies pursuing the Ruinable energy of wind idiocy, but because wind is so much worse than useless, society has to pay for the inefficient use of back up power plants, massive costs for grid balancing, massive subsidies for wind junk energy, massive costs for grid improvements, massive environmental impact, etc. etc.

Wind is so much worse than useless.
