Hi, Le Mon, 25 Jan 2016 11:37:57 +0100, Brandt Dainow <bd@thinkmetrics.com> a écrit: > Hi - I am not sure the figures for energy consumption will stand close > examination. I have read the paper for which Alexandre kindly provide > the link. Its source for these numbers is an article in ZDNET, which is > a commercial, not peer-reviewed, publication. In which they state: > > "Dans 25 ans, si les technologies informatiques ne progressent pas, > l’internet consommera autant d’énergie que l’humanité en 2008. C’est le > calcul qu’a réalisé Gerhard Fettweis de l’Université de Dresde." Funnily, I've discussed with someone from Ademe about this point and he confirmed it was a study from Dresden. I could ask him the exact source. This said, I think part of the group interest could be to find means to improve the way we access the source behind such studies (that's just one example). > They also cite a number of studies making claims such as "one search of > Google uses the same energy as one hour's use of a lightbulb." Which I haven't mentioned myself ;)) Mainly because the group, again, should not be just about IT & energy to my mind. > The studies they quote are not researched, but uncited claims made by > eco-groups, such as Green IT.
