Three wind turbine blades have been successfully installed on the Bahrain World Trade Center, a twin skyscraper complex. This is the first time that a commercial development has integrated large-scale wind turbines within its design to harness the power of the wind. The three massive turbines, measuring 29 meters in diameter

That's an amazing building. And, as far as the wind power goes, it's commendable that they're there.
However, with only three on a building that size, they're not supplying much energy I don't think.
Especially given that they can't rotate to track the wind patterns (probably not as big an issue here, since it's a coastal bldg and therefore most of the wind is coming in one direction).

it certainly is a neat idea. i would assume that they already planned out how much wind they get there and that the cost of building/upkeeping the blades is less than the price for the amount of energy they will receive.

GE makes a 3.6MW turbine, if all three of those are that good, it's a 10.8MW power plant. I imagine that has to at least be good enough to take care of their electric bill.
quote: The three massive wind turbines, measuring 29 meter in diameter, are supported by bridges spanning between the BWTC's two 240-meter high towers. Through its positioning and the unique aerodynamic design of the towers, the prevailing on-shore Gulf breeze is funnelled into the path of the turbines, helping to create even greater power generation efficiency.
Once operational, the wind turbines will deliver approximately 11-15% of the BWTC tower's energy needs, eliminating around 55,000 cubic kgC of carbon emissions into the environment every year. Incorporating the wind turbines as an alternative source of energy for the buildings will generate 1100 to 1300 MWh per year, which is equivalent to lighting 300 homes for more than a year and will create substantial annual savings.
