The United Arab Emirates – a country enriched by its massive oil reserves – is looking to position itself as a leader in a post-petroleum world. So they’ve built Masdar City, a low-carbon, zero-waste urban center that could sustain a 40,000 person population, 1,500 clean tech businesses, and 50,000 commuters -- while using 20% of the power of a conventional city of a smaller size. The centerpiece of the project is the Masdar Institute of Science and Technology, a post-graduate university established in partnership with MIT that aims to be a hotbed for future innovation.
