Jon Koomey: Luiz, thank you very much for that gracious introduction.
Jon Koomey: This has led to more popular presentations of this.
Jon Koomey: I'd say luggable is more like it.
Jon Koomey: but doubling time for computations per kilowatt hour, 1.6 years or so for all computers, 1.5 years for PCs and slightly
Jon Koomey: But what it says is that if we're, you know, if we, again, can radically change how we do this computing then there's
Jon Koomey: So the question is, have I looked at the relationship between the rise in efficiency and the rise in total energy use of computers?
Jon Koomey: So the question relates to the idea that somehow as you, you reach kind of a saturation in the performance of the, I'm sorry, the need for people's, for computing
Jon Koomey: That's one example.
Jon Koomey: You have that scale.
Jon Koomey: Okay. So this is a very interesting thing because you, how much do you think a scale costs?
Jon Koomey: 20 bucks, 30 bucks.
Jon Koomey: Chemical? male #4: Batteries, cause I can see that there's this like, on a log scale you have this straight line for computing power increasing over the decades but what's been the situation
Jon Koomey: OK, so the question is on the rate of innovation in chemical batteries and obviously the trends are, the changes are much slower.
Jon Koomey: So you have a bunch of things going on there, so the question relates to what have been these kinds of aggregate trends in total electricity use and how does that
Jon Koomey: Yes, so the two percent- male #6: so it's the total.
Jon Koomey: for data centers, two percent for data centers includes everything related to the infrastructure.
Jon Koomey: The cooling, fans, pumps, everything like that.
Jon Koomey: it's a good question.
Jon Koomey: Yeah, so the question relates to looking at software efficiency as opposed to hardware and this is to me, actually this is a fascinating area because in the past
Please help me in welcoming Jon Koomey.
the ENIACs and the- Jon Koomey: So that's a good question, actually, for this particular set of trends I did not include cooling cause I wanted to get at the characteristics of the IT equipment itself.
male #2: Osborne. Jon Koomey: Osborne, yes.
Luiz Barroso: $100. Jon Koomey: $100.
male #5: Right. Jon Koomey: So, my best guess now is we're talking single digit percent in the US for total direct electricity used by IT equipment but what you're seeing is, let's call it five
You recognize this? male #1: Altair Jon Koomey: Altair 8800.
Luiz Barroso: My name is Luiz Barroso and thank you for coming here and helping me welcome Jonathan Koomey to Google today.
