Skyscraper with wind PowerStation

Wind turbines on Bahrain World Trade Center started to move. They are fully integrated into the design of the building. The sail-shaped buildings on either side are designed to funnel wind through the gap to provide accelerated wind passing through the turbines. They are expected to provide 11% to 15% of the towers' power consumption.
