message: I have been reading lately that ICs are no longer as sensitive to temperature variations and that the comment:
:"Additionally, it is somewhat less stress on integrated circuits (especially the CPU) to be always warm, rather than fluctuating between cold and warm, because temperature changes are generally more damaging than being at a reasonably warm temperature all the time.
is no longer recommended.

HP rp5700 PC achieves gold status for the Electronic Products Environmental Assessment Tool (EPEAT).  EPEAT-registered electronic products will become 95 percent of all federal agency purchases...  The Electronic Products Environmental Assessment Tool (EPEAT) is used to rank computer desktops, laptops and monitors based on their environmental attributes. The three-tiered EPEAT rating system includes 23 required criteria and 28 optional criteria, such as the reduction or elimination of environmentally sensitive materials and energy conservation... HP lab tests have found that the rp5700 desktop PC, in its maximum energy-efficient configuration and paired with an HP flat panel monitor, may help customers save as much as 80 percent in power consumption over previous generation systems using CRT monitors.

message: A few questions the article left me with:
*"Support for S3 Standby and G2 Soft-off ACPI states have been difficult to achieve or undesirable for free operating systems" — Why?
*Why isn't there any mention of the notorious lack of efficiency within PC power manufacturers and Energy Star's 80 Plus initiative?
*Why does the section on "Alternatives to low-power states" mention the reduction of noise? What's noise got to do with lowering the power consumption and recyclability of parts, etc.?
*Security risks and how to avoid them are in my opinion irrelevant to the section. I don't see how it's even remotely pertinent to the discussion. Samuel Grant 01:48, 2 August 2007 (UTC)
replies: text: I just rewrote the "Alternatives" section.  I think that it was originally written from a free-software perspective; rather than discuss the aspects of ACPI that are pertinent to green computing, it simply dismisses them as "difficult" or "undesirable".  I hope the new section is clearer on this subject.  I also added info on power supplies and the 80 Plus initiative, and I took out the fluff on noise reduction. — EagleOne\Talk 18:38, 17 September 2007 (UTC)

thread_title:  Some questions 

message: The Hibernate article links here, but this article doesn't say anything about hibernation. 
When I came to this article I wanted to know if hibernation was more or less energy efficient than shutting down completely, anyone know? Is hibernation a complete shut down only with the current state saved? (th reason I ask is that on my desktop comp, when I press hibernate, the num lock light stays on and I can't work out why). I found both articles didn't really answer the questions I had about hibernation.  —The preceding unsigned comment was added by 87.194.208.99 (talk)

message: The article does not seem to clearly differentiate energy efficient systems from low power systems.  I have noticed similar confusion in discussions of ecology and computing elsewher
e.g. people proposing folding@home (a compute intensive job) on something like a Via C3 or Intel D201GLY2 (slow, low power computers), when a higher efficiency computer (e.g. Mac Mini Core2Duo) would do a lot more work for the energy input.
I think it would be worth pointing out that there is more to high efficiency than low power.  (Of course, if a system doesn't have much to do and is high efficiency, then it will be low power.)
The Green500 might be a useful reference for this.

"
Energy star certified power adapters for storage devices reduce power consumption 30 percent on averageEnergy Star Website Low-power hard-drives that reduce fan usage, automatically shut-down during inactivity and use other low-power features can reduce power consumption 90 percent.Energy Savings Calculator and Fabrik website"
here for discussion.
The main problems with this are lack of WP:RS, and apparent WP:OR.
The image is of a drive that is marketed as "green," but no WP:RS are provided to establish that.  (Manufacturers claims are just marketing, need third party analysis.)  The other claims about low-power hard drives again appear to be based on marketing, lack sources and lack generality.  (Only apply to one device, not clear what comparing to, ...)
It is debatable how "green" an external drive is (a larger case housing the computer, drives, etc. may be more efficient than separate cases/power supplies/...  
Likewise the energy star information lacks context (putting it here seems to imply that an external drive may be green, WP:OR).
Steel is also recyclable (and takes less energy to produce, ...; What is non-recyclable aluminum?)
The energy savings calculator link used in the sources has no apparent relation to any of this. Zodon (talk) 21:04, 26 November 2008 (UTC)

thread_title:  Propose removing Deployment section 

message: Ok, I took a stab at cleaning it up.  Would appreciate thoughts and help from other editors.  Please put this article on your watchlist and keep an eye out for further attempts to spam/hijack the article.  Or better yet, improve the article.  I don't have the expertise to do that, unfortunately, so I did what I could.
Anyway, sorry I didn't go into blow-by-blow details in the edit summaries, but I felt like I was reading someone's rushed college paper; this article had (may still have!) so much vague generality, plagiarism and spam-linking ... I feel dirty.  There's a lot of this San Murugesan guy who had entire chunks from his articles copied wholesale without attribution.  Even if they had quotation marks/attribution, it seemed to be mostly an outline of how to plan a "solution".  There weren't very many actual facts being presented; it was very much more of a how-to, and forgive me, but it was very Dilbert-esque.  I'm still somewhat ambivalent about the remnant sentences I placed under the "Approaches to green computing" header.  His definition of green computing in the lede seemed useful, though I trimmed a ton of ballast from the quote.
There were other more minor instances where a sentence or two got lifted somewhere; I put quotes around some and deleted others.  There may still be a lot of it left in this article; I simply don't have time to copy-paste every sentence into Google.  The green conference/company/article spam was tremendous,  Two, even three mentions of the same website in the same sentence.  Ick.  Can I have a wiki-shower?

thread_title:  Cleanup 

message: I'm new to editing Wikipedia pages so I'd love to hear some feedback before I actually try to edit one.  I have an interest in green computing and have an idea about adding some content to this site.  I thought a new section on green computing education might be worthwhile.  I've noticed that there are a number of certifications (some mentioned briefly in other Wikipedia pages) that have, to a degree, an emphasis on green computing.  Even though some may be listed on other pages, I think consolidating them here might be a good idea.  Also, there are some colleges around the world that have started, or are thinking of starting, computer classes and programs that emphasize green computing techniques.  I think mentioning those efforts, and maybe where some of them are taking place, would be useful information.  I think this could be a nice edition to the site.  Any thoughts?

thread_title:  New Green Computing Education Section? 

message: I have noticed that there is a general lack of the term “reuse”, one the three R’s of waste hierarchy, in this and other recycling articles. Being “green” does not mean simplistically recycling straight into raw materials. In Germany they disassemble junked cars and reuse certain parts to avoid environmentally expensive manufacturing. If you look at electronics and mainly computer recyclers, it’s tossed right into the scrapper though most non-hard drive parts are reusable and may not be manufactured anymore yet needed. It should be pointed out in the articles that many recyclers currently refuse to practice reuse thought it may be more profitable. I was trying, but could not figure how to successfully interject these concepts into these recycling articles because these articles seem to be constructed to have a one tracked focus solely on resource recovery recycling.Septagram (talk) 20:58, 14 June 2011 (UTC)
