The report says "One of the most recognized estimates of the IT sector’s footprint was conducted as part of the 2008 SMART 2020 study, which established that the sector is responsible for 2% of global GHG emissions".<br /><br />Sorry for the misunderstanding: it's the whole sector, not data centres alone.DavidKThorpehttps://www.blogger.com/profile/04215770376688861114noreply@blogger.comtag:blogger.com,1999:blog-18727745.post-74555396207246667172012-05-21T16:00:58.655+01:002012-05-21T16:00:58.655+01:00Data centres on their own do not produce 2% of GHG...Data centres on their own do not produce 2% of GHG.

Not a particularly clever figure because electricity consumption is usually expressed as W/h. Consumption not potential load. Nevertheless, global electricity generating capacity is multiple TWs & electricity generation accounts for only a third of energy use.<br />Bear in mind,also, elecgen is all of the nuclear, hydro & other non GHG producing energy routes.<br /><br />I'll leave you to do the arithmatic.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18727745.post-55396322531479917242012-05-21T15:07:05.900+01:002012-05-21T15:07:05.900+01:00Then I'd respectfully suggest you go back &...Then I'd respectfully suggest you go back & re-read it.bloke in spainnoreply@blogger.comtag:blogger.com,1999:blog-18727745.post-71959698487630544262012-05-21T14:40:56.817+01:002012-05-21T14:40:56.817+01:00The figure comes from the Greenpeace report refere...The figure comes from the Greenpeace report referenced in the post, the sources of which are, in turn, referenced in the report.DavidKThorpehttps://www.blogger.com/profile/04215770376688861114noreply@blogger.comtag:blogger.com,1999:blog-18727745.post-90136869276147271042012-05-21T14:19:55.242+01:002012-05-21T14:19:55.242+01:00"Data centres contain thousands of computers ..."Data centres contain thousands of computers that store and manage the world's rapidly growing accumulation of data for consumption at a moment’s notice. They consume a tremendous amount of electricity and are responsible for around 2% of global GHG emissions."<br /><br />It would be absolutely fascinating to know where you get this figure from. You have specifically said 'data centres, not the world's total data processing needs. And as a proportion of total GHG emissions not just those derived from electricity generation.<br />At a rough guess, I'd say you were out by half a dozen orders of magnitude.bloke in spainnoreply@blogger.com
