It’s no secret that the servers behind every Web 2.0 company, bank Internet site and corporate e-mail system are consuming ever larger amounts of power. But now a Lawrence Berkeley National Laboratory study to be released Thursday has quantified exactly how much.
Servers in the United States and their attendant cooling systems consumed 45 billion kilowatt-hours of energy in 2005. That’s more than Mississippi and 19 other states, according to study author Jonathan Koomey, a scientist at Lawrence Berkeley National Laboratory and consulting professor at Stanford University.
And the computers’ electricity appetite is still growing fast.
