Google Wants Energy-Efficient Hardware

New York Times reports that Google has some tips for saving energy.

"Google is calling on the computer industry to create a simpler and more efficient power supply standard that it says will save billions of kilowatt-hours of energy annually.

In a white paper to be presented Tuesday on the opening day of the Intel Developer Forum here, two leading data center designers at Google will argue that the industry is mired in inefficiency for historical reasons, dating to the introduction of the first I.B.M. PC in 1981. (...)

The Google plan calls for a shift from multivoltage power supplies to a single 12-volt standard. Although voltage conversion would still take place on the PC motherboard, the simpler design of the new power supply would make it easier to achieve higher overall efficiencies."

Their experience with building efficient data centers might be helpful for the hardware manufacturers. For example, Google uses servers with Opteron chip from AMD as they are more power-efficient.
