"Data centers house everything from this blog, for example, to the massive Google search index (which is comprised of an estimated 450,000 servers).... Data centers are big dollar, and the level of security is intense. Data centers are a study in how to secure an industrial facility.... In a study released in February, Jonathan Koomey, a researcher at Lawrence Berkeley National Labs, indicates that the power consumption in the world's data centers will grow by 40% in the next 3 years after doubling in the past five." "Data Center Power Usage to Grow by 40% by 2010"
"We're now firmly in an interconnected and digital world, and that means lots and lots of servers.... 61 billion (with a 'b') kilowatt-hours, and that's for 2006, back when most people were just starting to discover Youtube ... when demand is lower, the algorithms know that they can power down a certain number of servers. There's a lot of savings right there. But it's the sensors that make the system smart enough to power down the right servers to maximize savings, making the air conditioning work more efficiently (about half of the energy used by a data center is for cooling)."
