Centre for Energy Efficient Telecommunications researchers have forecast that global wireless-cloud access will generate as much carbon dioxide as 4.9 million cars by 2015. CEET estimates that Wi-Fi, 3G, and long-term evolution (LTE) services will use up to 43 terawatt-hours of energy in 2015, compared to just 9.2 TWh in 2012. This is an increase of 367 percent and is based on estimates that cloud users will transfer 23 exabytes (1018 bytes) of data per month by 2015. The Australia-based CEET is a partnership between the University of Melbourne, Alcatel-Lucent, Bell Labs, and the Victorian state government. (ZDNet)(Centre for Energy Efficient Telecommunications)
