How Windows 7 Will Cut Computer Energy Consumption


Windows7logoThere’s quite a few reasons to cheer Microsoft’s (s MSFT) next-generation operating system, Windows 7, which launched today — it could drive down the price of computers, help you ditch Vista once and for all, and couldchange the dynamics of the memory business. But here’s another: Windows 7 has some nifty new power management functions that will help cut down on the energy consumption of your PC or laptop. It’s about time.

Back in June, Microsoft’s Chief Research and Strategy Officer Craig Mundie told attendees of the utility-focused Edison Electric Conference in San Francisco, Calif. that Microsoft had made a “big investment” into more sophisticated power management features for Windows 7. Mundie said Microsoft was working on features like adding smarter power management functions that can put a computer into a low-power state and wake it up again much more quickly than other operating systems.

While I haven’t tried out the new power management features, Microsoft details some of the more energy efficiency upgrades of Windows 7 here. The OS uses fewer background activities than a standard OS, so the processor doesn’t use as much power, it has a more energy-efficient DVD playback, automatic screen dimming, a more accurate battery-life indicator, and it powers off unused ports. The biggest benefit that the consumer will see is that your laptop will be able to run longer without plugging in.

But when it comes to fighting climate change, it’s an even bigger deal. Mundie said he expects Microsoft’s power management functions to start to dramatically decrease the energy consumption of computers starting in 2010, when the next cycle of products will make its way into the market. PCs, peripherals and printers are responsible for 60 percent of the energy consumption of overall information technology (25 percent from network infrastructure and 15 percent from data centers) and the IT industry is responsible for between 2 and 3 percent of the world’s greenhouse gas emissions according to researchers at the Climate Group and Gartner. So bringing down the energy consumption of our own computers will be very significant.



Ahh but now we have to wait and see what Apple bring out to compete against this.
I am sure as there should be a sneaking new mac on the way for this years 2010 christmas release.

Should be interesting who comes out on top with this one.

Looks like finally Microsoft is getting it right. Unwanted processes/resources must be freed in first place for any OS, other it would be a bloated system. But, now that its fixing the issues, marketing team is taking to its advantage and riding the train of GO Green.

It’s amazing how many different things people are thinking of to go green these days. It makes for good PR and marketing.


Dear G Ames, have you not noticed that “comparisons” no longer are comparable. They are fluff. “trying to make it real- compared to what” as the old jazz song put it is more true than ever. Stats about humongous rises (like of crime) from rediculously low base lines – the statistic only obscures the non-importance (up 100% from 1 is ony 2, for instance, or a battery use of 1.5 hours is 100% improvement over .75….but still sucks))

Comparasons without HARD numbers always make me suspect. And under what situations? Remember epa figures? now everybody plays the game and you, I and perhaps even a few others have gotten ‘sceptical.’

I’m setting in a library that just updatedd to 7 and the librarian is explaining to a lady across how its been so slow since….he thinks its because they don’t have enough memory for the “improvement.” less running, more memory? I could only suggest they would be well served with a certain “L” competitor!!!

Bill is half the man his Father is, his company is still pretending to be usefull….well, thats just my sour grapes taklkin…

That’s the article I’m commenting on :) What they don’t clearly say is whether W7 is more energy efficient than XP.

That is the question.

Instead they make a comparison with the disastrously energy hungry XP which no-one I know uses anyway (for many reasons, incl. energy efficiency)

G Eames

All very nice but the real question is

“Does Windows 7 use more power than XP or less power?”.

Nobody uses or needs Vista, so are MS green-washing us or not? Can’t they just be open and let us know the answer to that question?
