FOSDEM09: "Aggressive" Linux power managementFOSDEM09: "Aggressive" Linux power managementPosted Feb 13, 2009 23:02 UTC (Fri) by giraffedata (subscriber, #1954)In reply to: FOSDEM09: "Aggressive" Linux power management by dlang Parent article: FOSDEM09: "Aggressive" Linux power management
if you are dealing with a 30w baseline, reducing it by 10-15w is extremely impressive and even 0.5w can be noticable, but if you are taking about a 300w baseline 10-15w is barely noticable and 0.5w probably doesn't matter to much of anyone. What kind of impression are you looking for? It seems to me that the baseline is useless. 10-15w saves the same amount of money and the same amount of CO2 regardless of the baseline. Should we also ask how much the room lights draw? Because if there's 300 watts of lighting, a 10-15w savings is barely noticeable even if it's half of what the GPU formerly used.

saving 10w of power saves ~1KWH of power (currently running between$0.10 and $0.30) every 4 days. so over a year of your computer being idle you could save between $10 and $30. (although if your computer sits idle for an entire year you could save a lot more money by not buying it in the first place)
so I don't buy that saving the electricity is an end in itself.
for portable devices that reduction in power can mean that your battery lasts much longer, which is the thing that you really care about.

But what are you responding to? This thread doesn't say anything about saving electricity being an end in itself. Your post does, however, reinforce the parent post, by showing reason to save electricity without any reference to the baseline usage.

You both understand each other. Don't do this.
FOSDEM09: "Aggressive" Linux power management Posted Feb 14, 2009 17:38 UTC (Sat) by giraffedata (subscriber, #1954) [Link] You both understand each other. Au contraire. I'm completely mystified by dlang's post, in its context, and I think that may be because he completely misread mine. And you apparently read something into my most recent post that wasn't there as well.

I think it's obvious where you're both misunderstanding each other, and think if you'd step back and think for a moment you could either stop or have a pleasant conversation. If you require someone to draw you charts and graphs, I don't think I have time for that right now.

It looks like I've been misunderstood more than once.
