Why is Green ICT Important?
From the website http://greenit.net/whygreenit.html :
"Global carbon emissions attributable to ICT have been estimated at 2% to 2.5% of world totals - about the same as the airline industry - and as high as 5-6% of developed nation totals. McKinsey forecasts that the ICT sector's carbon footprint will triple during the period from 2002 to 2020. For office buildings, ICT typically accounts for more than 20% of the energy used, and in some offices up to 70%.
Although energy costs typically comprise less than 10% of an overall IT budget, in a few years they could rise to more than 50% according to a 2006 Gartner report. Many large organisations - such as Google - already claim that their annual energy costs exceed their server costs."
