The Bahrain World Trade Centre, under construction above, is being hailed as the world's first with an integrated wind turbine power source. The turbines will deliver 11%-15% of the building's energy needs.
We have to hope it will fare better than the Palestra building in London, which was also hailed as the world's first with integrated wind turbines. The turbines weren't as well integrated into the overall design, just lined up on the roof, and they had to be removed after some months because of a failure.

They are being replaced with two new sorts which are to be tested to find the more successful.
They are much smaller turbines than the ones in Bahrain, producing only 4% of the building's needs. The photovoltaic panels increase the savings to 10%.
