I’ve been mulling over some statements in by Alexander Klose. He says logistics has become the “third largest sector of the economy”. That in Germany 10% of energy use is accounted for by data centres – and that there are more than 5 million worldwide, whose CO2 emissions (from their production and use) is approaching those of global air traffic.

A modest amount of rooting around online hasn’t enabled me to verify these rather eye-opening facts, if they’re correct. Does anybody know of sources for such figures? (This Scientific American article reports some signs of decoupling of CO2 emissions from growth in the aggregate; prior to 2000, the energy-intensity of GDP growth had apparently been declining.)
