Masdar City, the world’s first zero-carbon city, sits just outside of Abu Dhabi. Designed by the British firm Foster + Partners, the city was created to inspire urban planning of the future and runs entirely on renewable energy sources. The whole city is built on an advanced energy grid which monitors the output of every single switch and appliance. Automobiles will be banned within the city, in favor of driverless “personal rapid transport” systems. Its current residents are 120 graduate students and staff of the Masdar Institute of Science and Technology, who are creating the future of sustainable energy while living in its prototype!
