please don't. They're rather inefficient and therefore require huge amounts of cement to construct which accounts for about 10% of our greenhouse gases. Yes, as cement cures it unloads tons of CO2 (almost a ton of CO2 per ton of cement). It's simply how cement is formed from limestone that releases so much CO2.

A much more viable solution is solar updraft towers, which undoubtedly needs cement as well but because they can be built anywhere on Earth mitigating much of the need for more wind farms distributing electricity over such long distances from where wind farms are productive to areas where they are not that results in huge loses of energy.

We have built them, we know they work, and for less than the cost of bailing out all those banks in 2008 we could have built them across the entire US and been off coal completely.

They are by far our best chance at meeting our energy needs.
