The other night I ran across an interesting tidbit in the most recent issue of MacWorld… It seems that a recent study revealed that the amount of electricity required to run the world’s computer servers has doubled since 2000. As of 2005, it cost businesses worldwide $7.2 billion run their servers (just considering the energy costs). Moreover, based on current usage patterns and market forecasts, computer servers could burn up to to 76% power by 2010.
Obviously, this sort of energy consumption isn’t just expensive… It’s also bad from an environmental perspective. Interestingly, companies ranging from niche players such as Dreamhost to behemoths like Yahoo! are going carbon neutral. As an aside, Yahoo! did the math and discovered that going carbon neutral is, in their case, the equivalent to “shutting off the electricity in all San Francisco homes for a month. Or, pulling nearly 25, 000 cars off the road for a year.” Wow. That’s a lot of energy!
