Quotes (Global Warming) “Eleven of the last twelve years ( ) rank among the twelve warmest years” “... is very likely due to the observed increase in anthropogenic GHG concentrations” “...many natural systems are being affected by regional climate changes” IPCC 4th Assessment Report, 2007 “‘four degree world’ spells potential disaster” World Development Movement - Two degrees of separation, November 2007

Quotes (IT Power Consumption) “ICT industry produces 2% of global CO2 emissions” “23% out of it from data centres” Gartner - Gartner's Data Centre Summit 2007, October, London "About 10% of the UK's total energy consumption currently relates to power running through IT equipment“ Richard Barrington, head of Public Policy for Sun UK and Ireland and UK government advisor - ICT Forum Wales 2007 “Servers operate most of the time at between 10 and 50 percent of their maximum utilization levels” Google - The Case for Energy-Proportional Computing, December 2007 “It is estimated that 40% to 70% of the operating costs for a data center are power and cooling” Dell – VMWorld 2007

Quotes (IT Going Green) “BT currently uses over 0.7% of the UK's electricity consumption” “Over the next 9 years (2016), we plan to build wind farms that will yield 25% of BT's electricity needs.” BT “Our goal is to produce ONE GW of renewable energy capacity that is cheaper than coal.” 1.6 MW solar power to provide 30% of Google's peak electricity demand in Mountain View headquarter Google Microsoft Unveils Wind Powered Virtual Earth 3D Data Lab in Colorado Microsoft
