Server energy consumption exceeds that of Las Vegas?

Amazing stats buried in a Wired magazine article:

"If it's necessary to waste memory and bandwidth to dominate the petascale era, gorging on energy is an inescapable cost of doing business. Ask.com operations VP Dayne Sampson estimates that the five leading search companies together have some 2 million servers, each shedding 300 watts of heat annually, a total of 600 megawatts. These are linked to hard drives that dissipate perhaps another gigawatt. Fifty percent again as much power is required to cool this searing heat, for a total of 2.4 gigawatts. With a third of the incoming power already lost to the grid's inefficiencies, and half of what's left lost to power supplies, transformers, and converters, the total of electricity consumed by major search engines in 2006 approaches 5 gigawatts.

Green WiFi and Mesh WiFi

Green Wifi "seeks to bridge the last mile internet access with nothing more than a single broadband internet connection, rooftops and the sun".

Mesh WiFi is a network technology and topology in which each user is also an wireless access point, moving signals to and from neighboring users to create a wireless network (the 'mesh') without a separate wireless infrastructure.

Google pushes energy-efficient power supplies

PC power supplies are said to waste over a third of the energy they consume. Google claims to have technology that reduces waste to 10% and offered to share it during a presentation at yesterday's Intel Developers Conference.
Surprisingly little coverage of this in the US media, but I found a good report from the UK print media.

EPEAT Computer Equipment Assessment Tool

EPEAT "is a procurement tool to help institutional purchasers in the public and private sectors evaluate, compare and select desktop computers, notebooks and monitors based on their environmental attributes. EPEAT also provides a clear and consistent set of performance criteria for the design of products, and provides an opportunity for manufacturers to secure market recognition for efforts to reduce the environmental impact of its products."
