Google to call for energy efficiency
Google will present a white paper at the Intel Developer Forum that calls for the computer industry to move from multi-voltage power supplies to a single 12-volt standard.
According to a report in The New York Times, Google will argue that the simpler design of the alternative power supply would make it easier to achieve overall efficiencies in PCs.
Google, according to the Times report, contends a design flaw dating to the introduction of the first IBM PC has led to "overprovisioning" in today's PC power supplies that is akin to "putting a 400-horsepower engine in every car."
Google, in its white paper, maintains that using the new power supplies in 100 million PCs running eight hours a day would save 40 billion kilowatt-hours over three years -- more than $5 billion at California's energy rates.

I am not in a position to debate the merits of a
single volt power supply but what I would like to
see is the pc power supply (main power supply)
having externally accessable voltages to power
peripheral pc components such as printers, scanners,
external modems, etc. It would be nice to eliminate
the ac adapters that pc peripherals require. We'd
probably save power from just this change alone.
That is what USB already does (within a 500mA limit I believe). I have a Canon scanner powered solely by USB, and it is several years old.
