The dean of a research institute at the core of Abu Dhabi's green-energy city said Sunday the government remains firmly committed to renewable power after recent shifts in the ambitious project's goals. Masdar City was originally conceived as a self-contained "carbon-neutral" community of 40,000 residents and even more commuters where cars would be banned and waste and water would be recycled.(AP Photo/Kamran Jebreili, File)
