Fight the power

Fight the power

Source: Jonathan Koomey, Lawrence Berkeley National Laboratory

A paper by Jonathan Koomey, staff scientist at the Lawrence Berkeley National Laboratory, estimating total power consumption by servers in the US and the world.

The study estimates total electricity consumption by combining measured data and estimates of power used by the most popular servers with data on the server installed base.

The research suggests that aggregate electricity use for servers doubled over the period 2000 to 2005. Almost all of this growth was due to a rise in the installed base of servers, as opposed to any increase in power consumption per unit.
