“Internet Responsible for 2 per Cent of Global Energy Usage"
October 26, 2011 | Jim Giles, New Scientist

How much energy does the internet use? It's hard to know where to start. There's the electricity consumed by the world's laptops, desktops and smart phones. Servers, routers and other networking equipment suck up more power.

ICSI in Geekosystem

When you’re trying to figure out statistics about something as nebulous and pervasive as “the Internet,” you’re going to have to performs some interesting mental contortions. After all, how many things out there are connected to the Internet? How many of those things would you consider to be actively “using” it, how much power is there in the world? All valid and difficult questions, valid and difficult questions that Justin Ma and Barath Raghavan, of UC Berkeley and the International Computer Science Institute respectively, were determined to tackle.

"Internet Accounts for Almost 2 Percent of the World’s Total Energy Consumption"
October 30, 2011  |  Paras Shah, The Daily Californian

UC Berkeley researchers have estimated that it takes between 1 and 2 percent of the world’s energy to construct, run and maintain the Internet. According to the research, which will be presented Nov. 14 at the Workshop on Hot Topics in Networks in Cambridge, Mass., the Internet uses between 170 and 307 gigawatts — about 1.1 to 1.9 percent of the 16 terrawatts of energy consumed by humanity.

“BufferBloat: What’s Wrong With the Internet?”
February 2012 | Vint Cerf, Van Jacobson, Nick Weaver, and Jim Gettys, Communications of the ACM

Internet delays are now as common as they are maddening. That means they end up affecting system engineers just like all the rest of us. And when system engineers get irritated, they often go looking for what's at the root of the problem. Take Jim Gettys, for example. His slow home network had repeatedly proved to be the source of considerable frustration, so he set out to determine what was wrong, and he even coined a term for what he found: bufferbloat.
