No - but willing to guess that they either took the total energy consumption and divided it - or took a reasonable number x number of servers; assumed 100watt and took it from there. > "a typical Google search on a desktop computer produces about 7g (0.25oz) of > carbon dioxide" Looking at Alexa and friends - we're talking some 1-3 10^9 of queries per day; so, say, 750 10^9 a year. So assuming about 500 gram per kWh we get something like 150 10^9 kWh/year dived by the about 10k hours in a year => 15 10^6 Watts of contineous use; say 100 watt per machine => 150k machines. So that sounds pretty low (unless I made a mistake) as every machine generally carres 1-2 extra 'machines' for cooling at the very least. Hmm - off by 10 ?
