'Greening IT'

摘要

Imagine a mid-sized country populated entirely by computer servers. Ridiculous? Not a bit. Datacenters worldwide already consume as much energy as the whole of the Netherlands. What's more, these machines are multiplying at a staggering rate. The energy consumed by datacenters in the U.S. accounts for 1.5% of national consumption. If left unchecked, the figure will quadruple byrn2020, according to a study released by McKinsey and the Uptime Institute in 2008.
