I recently watched the BBC Human Planet documentary. If you have not watch those yet, please do 😉 www.bbc.co.uk/humanplanet/
On of the things that I was not aware of, was the building of the Masdar city (http://en.wikipedia.org/wiki/Masdar_City), which aspires to be one of the most sustainable cities in the world, with approximately 6km2 . Masdar City is an emerging global clean-technology cluster that places its resident companies in the heart of the global renewable energy and cleantech industry. You will Masdar City at 17km from Abu Dhabi, Masdar City. The capacity is for 40,000 residents and hundreds of businesses, and it will integrate the full range of renewable energy and sustainability technologies, across a living and working community. As with most dynamic technology clusters, the city has a top-notch research university that is a source for innovation, technologies, R&D and highly skilled graduates.
