>> Data centers are ridiculously efficient. The latest generation of data centers from the big cloud providers have PUE in 1.07 territory, which would've seemed like pie-in-the-sky ludicrousness even 10 years ago. Every CPU cycle that's done in a data center instead of on someone's client machine or on-prem server is a decrease in power consumption. << Do you know what is the global consumption of energy of data centers in 2016 ? It is same as consumption of energy of global aviation. Think about it, the energy consumed by Data Centers is equal to all commerical planes world wide flying. (source: realclearnergy podcast) They may very well be efficient, that is shit load of energy and that is point.

> Do you know what is the global consumption of energy of data centers in 2016 ? It is same as consumption of energy of global aviation. Think about it, the energy consumed by Data Centers is equal to all commerical planes world wide flying. Does the global aviation cost comprise just the cost of flying planes, or does it include the cost of maintaining mainframes for flight bookings? Also, how does the consumption of power by data centers compare to the consumption of power by all consumer PCs/workstations? That's kind of the comparison we're looking at here.

Energy consumption of data centers as of 2016 shows they are a major component of total energy consumption and therefore worth watching. It doesn't imply how that will affect _growth_ in energy usage over time. You have to look at change over time taking into account demand, supply and efficiency together in an analysis like this http://www.datacenterknowledge.com/archives/2016/06/27/heres-how-much-energy-all-us-data-centers-consume http://www.datacenterknowledge.com/archives/2016/06/27/heres...
