First Actual CPU Energy Use Statistics Published

BBCWatcher writes "CNN is reporting that the U.S. Environmental Protection Agency in August asked server manufacturers to develop 'miles per gallon' ratings for their equipment that would provide accurate assessments of energy efficiency. IBM says it is now providing 'typical usage ratings' for its line of z9 mainframe computers, in addition to previously available maximum power ratings. More than 1,000 z9s around the world started reporting (with the owners' permission) on May 11th their actual installed power and cooling demands, so IBM can publish statistics such as how much energy is required to turn on an additional processor to run multiple Linux virtual servers. The answer? About 20 total watts. 'Over time every vendor is going to be asked to provide typical energy use numbers for their equipment. It's what the EPA wants, and this allows us to move beyond simple performance benchmarking to energy benchmarking.'"

energy efficiency has been tackled already

By these guys [slashdot.org] back in 2000. The potato powered web server.. We could help our farmers, and power our data centers with beuwolf clusters of potatoes!

...if only the sysadmins weren't constantly dismantling the power supplies, dropping them in hot oil, and eating them, that might work!

*REAL* programmers...

*Real* programmers eat microwave popcorn. However, they use the heat from the CPU to cook it instead of using an actual microwave. *REALLY* good programmers can even tell which process is running by the rate of popping.

So, the internet is a series of tubers then?

miles per gallon?
