The Cloud Begins With Coal
Now, the scale and the character of the ICT ecosystem are changing. Not only will there be more and
bigger data centers coming, but the evolution of computing towards mobile platforms, smart phones
and tablets creating the “Mobile Internet” is radically altering where and how data are produced and
used, collaterally changing the nature and scale of the network infrastructure.

The Mobile Internet, the Cloud and Big Data revolutions create economic opportunity and generate
enormous efficiencies. But just how big is the global ICT ecosystem now, and how big will it become?
How much electricity is consumed, and will be consumed in the future, by the entire ICT ecosystem?
The new and emerging digital devices and services for consumer and businesses have created
opportunities unimagined in scale or character by any visionary during the heyday of “irrational
exuberance” of the 1990s when the Internet began. Soon more data will be associated with non-‐PC
devices than PCs – even as PC-‐centric traffic itself doubles.
