[Commentary] You can draw a straight line between the popularity of Facebook and a developing boom in Internet infrastructure. Earlier this month, Facebook announced that it has 300 million subscribers. The fantastic growth of the company is mirrored by the rapid advancement of Twitter and many other web services that have spawned ecosystems of their own. While these services get most of the media attention, a much bigger story is what lies beneath — the Internet's infrastructure and the grid that powers it. "We have entered this new era where essentially everything is on all the time," Alan Meier, a senior scientist at Lawrence Berkeley National Laboratory, recently told The New York Times. And increasingly, everything is connected to the Internet. The biggest impact is being felt by the electricity grid. The power consumed by servers alone doubled between 2000 and 2005 to about 123 billion kilowatt-hours. Data center power use is likely to increase another 76 percent by 2010, according to Jonathan Koomey, a researcher at Lawrence Berkeley and Stanford University. I can't imagine the energy implications of what's coming next.
