Bahrain World Trade Center, Manama, Bahrain

Possibly the greenest building on earth.Height: 240 meters

Cost to build: US$150 million

Completion date: 2008

Fast fact: It was the world’s first wind-powered mega-structure.
No doubt the futuristic Bahrain World Trade Center has given the island’s skyline a big, bright slap in the chops. But the maritime connection doesn’t stop at its stunning silhouette. 

The two sail-inspired towers that reach vertically more than 240 meters are joined by three giant wind turbines in the middle to harness the power of nature, generating approximately 13 percent of the towers' total energy needs.

In addition to showing its deep pockets, this emphatically sci-fi building also speaks volumes about Bahrain's environmental consciousness.

Overall structure

Not wanting to be left behind by Saudi Arabia and Dubai, the country of Bahrain has been approving some interesting and eye-popping developments in the realm of green architecture. Especially interesting is the new Bahrain World Trade Center located in the city of Manama. The 50-story complex contains two identical towers that rise over 240 meters in height. The sail-shaped buildings offer a visually striking silhouette, appropriately referencing the maritime environment of this small Middle Eastern island, and boast one very unique feature — 3 giant wind turbines tying the two “sails” together.
