Masdar City, Abu Dhabi: Sustainability

3 of 21

Eco-warriors, meet Mecca: once completed, Masdar City promises to be the world's most sustainable urban locale. The city will be powered by solar and wind energy; recycle the majority of its wastewater; and try to reduce its waste to zero via unorthodox methods such as transforming biological waste into soil and fertilizer. A perimeter wall surrounding Masdar will keep desert winds at bay, while shaded streets combat the blazing sun. As for gas-guzzling cars, they're eighty-sixed from city limits (electric vehicles are allowed), replaced by mass transit and pod-like vehicles that travel underground. Some systems are already operational, but the city will come online fully in approximately 2020.
