The world's largest concentrated solar power plant, Shams 1, launched on Sunday. Taking three years to build, the $600m plant is located in Abu Dhabi's western region, in the heart of the UAE's hydrocarbon industry. At full capacity, the 100 megawatt Masdar, Total and Abengoa joint-project will power thousands of homes in the United Arab Emirates and displace 175,000 tons of CO2 a year
