When it comes to data centers, the color green is good. It’s good for the overall corporate image as well as the bottom line for companies to have environment-friendly data centers. And it’s good for the companies selling computing equipment that, if not quite green, at least looks green from a distance.
What no one’s talking about, though, is just how close the entire computing industry came to a total meltdown over the past half-dozen years. What saved it, in the end, was energy efficiency. This is ironic considering that data centers as an industry segment are one of the single largest consumers of electricity. At last count they consumed about 2% of all energy being produced in the United States, and that number could well rise over the next few years as more video and graphics are added to the mix.
