Credit: Masdar This is the surprising question I found myself asking as the cool winter sun set over the hazy skies of Abu Dhabi, the oil-rich emirate that played host this week to the 3rd World Future Energy Summit. The meeting has attracted an impressive line-up of movers and shakers in the world of climate change and the booming renewable energy industry, as well as a sizeable gathering of political and business leaders from 120 nations. There were 23,000 visitors over four days, 600 exhibits from 50 countries spread over 40,000 m 2 of floorspace at the city’s high-tech new exhibition centre, itself part of a US$2.2 billion micro-city of skyscrapers still partly under construction. Everywhere you go in this city of 900,000 people, there is a frenetic pace of construction – with several building sites operating 24 hours a day.
