Microsoft Boasts of Tiny Energy Saving With IE

judgecorp writes "Microsoft has sponsored research that indicates that its Internet Explorer browser uses less power than the competition, Firefox and Google (there's no explanation of what causes the difference). However, the difference in power use is not really significant — it's about one Watt when browsing. Browsing for 20 hours at this rate, the IE user would save enough power to make a cup of tea, compared with Firefox and Chrome users. That Microsoft commissioned and published the report seems to indicate a certain desperation to Microsoft's IE marketing efforts."

...a certain desperation to Microsoft's IE marketing efforts

Not at all. If you run a company with 10,000 PCs then it's a significant saving.

Re:It adds up

What company is stupid enough to pay for 10,000 Windows licences?

Re:It adds up

[aglider]

Yes, only if all of them are just browsing the internet all the time.
But if they are making real work, maybe the results would not be that good.

Re:It adds up

[Joce640k]

Well..certainly not one that would allow their employees to have two extra cups of tea per week.

Re:It adds up

[ameen.ross]

I fail to see how using IE over the other major browsers yields a net saving. Power usage is only one factor. And it still remains to be seen how objective this sponsored study really is, as MS doesn't have the best track record in that regard.

Thousands of companies a lot wealtheir and more successful than you, dipshit.

Re:It adds up

[wvmarle]

The difference is about 5% in power use of the computers only. Which may translate to 1% or less overall savings.

However IE is also slower in rendering pages, causing productivity loss (a few seconds a page of employee time eaten up) which easily costs more than the energy cost saved.

Re:It adds up

[jimshatt]

And besides that, you'd really need to calculate energy cost per rendered page. I might be able to make a browser that uses half the energy competing browsers use, but renders 2.5 times slower. But yeah, productivity loss is probably even more significant.

You have to consider the source here too ... its Microsoft. It was "sponsored" research, which translates to "rigged" test with rigged results. So it is indeed done for marketing purposes, or why else do it. Probably a simple web page with little css or js. You can't take anything they say at face value.

Re:It adds up

[Anonymous Coward]

Sure. And same company would have to pay additional admins to troubleshoot security problems.

Also, same company probably would have higher losses in performance of employees who use mentioned browser.
Doesn't look like your argument holds the ground.

Re:It adds up

[wvmarle]

Rendering is only part of the energy use.

YouTube is at the top of the power-hungry pages, which is of course caused by the flash plugin playing video. Other pages will have moving ads, that also continue to use energy. Rendering will likely cause a power spike when loading a page, however thinking of dynamic pages like /. discussion, where you can show and hide pieces of the page, rendering is more continuous. So the time spent reading, commenting, the amount of extra comments opened: it all adds to power use.

They must have come up wiht some "typical use case" and then replicate that over the various sites they tested. And it is of course telling that barebones site Craigslist is the most energy efficient.

That is the biggest factor that makes this dumb.

So you save a little electricity - how much are you losing elsewhere in lost productivity, insecurity, virus infestations, etc, because you are using IE?

Re:It adds up

[Anonymous Coward]

And no mention of test conditions... with the actual report containing niceties like this:

In addition, at the request of Microsoft we set the JavaScript timer frequency to “conserve power” in
the Windows power options. We found, however, that the default Javascript time frequency for all
computers tested was set to “maximum performance.” We did not investigate the impact of this setting
upon browser power draw.

Re:It adds up

[DeathToBill]

No it's bloody not. Honestly people have some weird ideas about arithmetic. If your average PC uses 100W then the difference in browser power usage, 1W, is 1% of that usage. It doesn't somehow magically become 50% if you're running 10,000 PCs - it's still 1%.

But, for the same of argument, let's do the math. A company with 10,000 PCs each consuming 100W during work hours is using 1,950 MWhr (100W * 37.5 hours per week * 52 weeks per year * 10000 PCs / 1000000 W per MW = 1950) per year to power those PCs. Retail electricity is around 12.86 p/kWhr, so they're spending £250k (1950 kWhr * 12.86 p/kWhr * 1000 kW per MW / 100 p per £) on electricity to power their PCs.

A company with 10,000 PCs presumably has 10,000 employees to use those PCs. Suppose they all earn the minimum wage full time, costing £12,000 each (£6.19 per hour x 37.5 hours per week * 52 weeks = £12,070.50 per year - call it £12k). Those 10,000 employees cost the company £120 million per year.

So our company with 10,000 PCs is spending £250k on electricity and £120m on wages. But wait! All those savings will add up! Suppose those users spend every working hour browsing the web. That means they would each save 1950 Whr per year (37.5 hours per week * 52 weeks per year * 1W). Retail electricity is 12.86 p/kWhr, so each employee saves a whacking great... um... 25p per year (1950 Whr * 12.86 p/kWhr / 1000 W per kW). Yes, all those savings add up to £2,500 across the whole company. That's 0.0021% of your combined staff and electricity costs.

Now suppose you live in the real world and not all your employees work in front of a PC all the time and they only spend about 75% of their time browsing the web when they do and some of them, God forbid, take a holiday every now and then. How much do those savings add up to? Sweet. Bugger. All.

Re:It adds up

Re:It adds up

[crutchy]

Re:It adds up

[Anonymous Coward]

1 W * 10,000 PCs = 10 KW * capacity factor. For the sake of the argument, let's pick a fairly high value: 25%. This comes to 2.5 KW. Retail costs are about $0.10/KWh right now, so this would come to a savings of $2,190/yr. For a company that has 10,000 PCs, this is nothing. The cost of paying 10,000 employees would be around half a billion dollars. The time it would cost the IT department to switch browsers, train users, and get everybody configured would exceed the cost saved by 2 or 3 orders of magnitude. Only an idiot manager would use this 1 W "cost savings" to require the users to switch to IE. Thus, it is likely going to happen in many, many places.

I guess you haven't tried IE10. It may be shit for a number of reasons but page rendering speed is comparable to other browsers, certainly not seconds longer.

A 1W saving is pretty good actually. Small Ultrabook type laptops usually only have 30-40Wh batteries so over an 8 hour run-time it could be 1/4 the machine's power budget.

Yes, but *time* adds up too ! I'd like to see the *total* consumption needed to run the benchmarks or render the pages. If IE is slower, not a surprise it consumes less instantaneous power. But in this case it would consume the power for a longer time.

Re:It adds up

[wvmarle]

I haven't used IE in ages, as there is no Linux version so can't even try it.

TFA however lists benchmarks as well, without further explanation, but based on the numbers I make up that IE is a bit slower than the others.

And the 1W saving is on a 15W base power draw for laptops, or 2W saving on a 38W desktop. That's just over 5% power saving - which is rather surprising to me, and in itself is asking for further investigation. Your low-power netbook won't have a 1w saving, more likely about 5% of however much power it normally uses.

Re:It adds up

[Anonymous Coward]

You can find the original paper with actual methodology and data linked in TFA, and yes, for low-power netbooks saving is more like 0.2W - and it's not consistently in IE's favor.

NOT THIS

The last couple of versions of IE have been far better than anything in the past and just as "safe" as firefox or chrome. I really only stay with firefox because of a handful of extensions and better ability to customize the layout. Not because of performance or security.

As to the power savings, sure take it with a grain of salt. But even taking it at face value and saying a savings of 1 watt per week per user we are talking on the order of a gigawatt per week. That is nothing to sneeze at if true. Of course, it is just a marketing ploy as 6 months from now the tables will be turned and Chrome or Opera may be in the "savings" lead.

I work at a company - finance sector - that has, last I heard, just shy of 70,000 employees around the world.

Every single person in this company is issued a Lenovo or an HP laptop, running XP (if it's an older laptop that hasn't been caught in the upgrade cycle yet) or Windows 7 (anything issued since last year, plus some early adopters who opted to upgrade their older laptops).

IE8 and Firefox 20-ish (forget the version number offhand) are our twin corporate standards for web browsers.

We ALSO have thousands and thousands of production servers running Linux, Windows and even a handful of Solaris and AIX boxes still. And we have a small percentage of our developers who have Macs, to support mobile app development.

There are many more machines than there are people, but every single person has a Windows desktop - it's the corporate desktop standard.

How do I know this? I was involved in the Windows 7 upgrade, and got to look at the platform breakdowns.

So if a company with 10,000 Windows computers has their 10,000 employees browse the web for 8 hours using IE instead of FireFox or Chrome then they'll save enough power for 4,000 cups of tea.

Or, since the article gives the figure of 1 watt saved per hour, 10,000 IE users browsing for 8 hours will save 80 kilowatts. Not a very big savings. You could replace a few incandescent light-bulbs with compact fluorescent or LED bulbs and save more energy.

This isn't exactly true.

Mostly because while 10,000 PCs is more than 1, the amount of liquid funds the company has is equally more than the amount 1 person would have.

Though that wouldn't stop accountants from trying to squeeze every last drop of blood out of them. :)

Re:It adds up

[Eivind]

Not really. Sure, if you multiply a tiny number for 10,000 then you get a higher number. But every other number rises for that company too, so the savings stay tiny relative to the rest of the budget.

1 watt saved times 10000 is 10 KW saved for every hour those computers are used for browsing. If an average corporate computer is used for browsing 10 hours a week, then you're talking a saving of $150 - $250/year, depending on how much AC they use and what power-prices they pay.

$250 on the budget of a 10.000 employee firm is no more noticeable than $0.25 in the budget of a 10 employee firm -- it's still a saving of $0.025/year pro employee. In practice, this is down in the noise.

Re:It adds up

[Eivind]

Not "probably" -- definitely.

A *one* watt saving is at $0.15 Kwh a saving of $0.00015/hour while surfing. If an average surfing employee costs $30/hour then we're talking a 0.005% reduction in cost for that employee -- if the employee surfs for 1000 hours/year, then that's a win if the employee, over those 1000 hours, waste no more than 3 minutes.

True, but GP does have a point. What if the scheduler really has some inefficiencies (IE bugs that need fixing) that only MS' devs know about? But let's not go down that rabbit hole.

Re:Browser energy?

[aglider]

In a real world system, nothing stands still and everything is in flux.
Unless you can finely account for every single CPU instruction and hardware activity to the browsing, then it's unlikely your "test with and without" will yield anything relevant.
Even if you reboot the system after every single test you won't be able to get the very same "execution environment".
And this is why I am asking: there seems to be not enough information on how the test has been conducted and measured.
To me it smells like crap. I could be wrong, but the smell is awful.

Re:Browser energy?

I normally don't care about browser power usage, until I'm trying to maximise the time left on my laptop battery, and then I play close attention to CPU usage and power consumption.

On my laptop Konqueror wins by a very wide margin when it comes to being able to browse the Internet for as long as possible on a single charge. Firefox and Chrome are absolute pigs by comparison.

Re:Browser energy?

[agm]

A better comparison would be IE running on the OS that is required to run it compared to Chrome running on a different OS. keep in mind that to run the IE OS you also need a vurs checker running. I'm sure the IE/Windows/Virus checker combination would gobble more power than, say, a Linux compiled from source targetted to the hardware and running Chrome.

In what world are you living that you get to pick your company's hardware and software based upon browser electrical usage?

If you have a virus scanner, it'll be running for all browsers.

on a different note, lynx would be way more power-efficient than IE :)

Re:Browser energy?

If only there was an electrical device you could connect to a computer and see instantaneous power usage. That way you cold open a page in IE, look at the power. Open the same page in Firefox, look at the power, etc.

you don't need a virus scanner in windows and even if you have one it probably won't save you anyway... hardened IE security settings and disabling of plugins should be sufficient unless you're into warez and porn, and if you're dumb enough to click on links in unsolicited email you deserve a good infection

Say that to average Joe user :-)

Re:Browser energy?

[Grishnakh]

You may believe this, and it may well be true, but good luck finding any large corporations where it's not standard IT policy for computers to run a virus scanner at all times.

The OP's point is sound: a better comparison would be to run Linux with Chromium or Firefox, versus Windows with IE and a virus scanner and all the other crap that goes with it (in a standard corporate build). Most likely, the Linux system will be more power-efficient overall.

and if you're dumb enough to click on links in unsolicited email you deserve a good infection

This is exactly why you won't find a corporate IT department that forgoes virus scanners on their employees' PCs. They have lots of employees that really are that clueless, and they can't afford a "good infection".

Re:Browser energy?

[Grishnakh]

That's not what the parent is asking at all: he's asking for an accounting of which parts of the Windows OS use power, and how much, not just the overall consumption. The implication is that other parts of the Windows OS are wasting power, compared to other OSes (namely Linux). Of course, this is all speculation; it'd be interesting if someone did do some measurements of some Linux systems (desktop and laptop, multiple ones of each, for better statistical data, and also using different Linux distros and DEs (Ubuntu/Unity, Fedora/Gnome3, OpenSUSE/KDE, Mint/MATE, Mint/Cinnamon, Mint/KDE, Mint/XFCE, etc.) running Firefox and Chromium, and compared this to the same systems running Windows (XP and 7 and 8) running IE, Firefox, and Chromium, to see how they all compared.

Megawatts worldwide

[Camembert]

It is a small saving on one computer, but take all the computers with IE in the world and it becomes a lot of megawatts. It wouldn't be a bad idea from an ecological viewpoint if this kind of efficiency became more important.

Re:Megawatts worldwide

[gbjbaanb]

amen to that. Its not just ecological issues that benefit from efficiency - there's a reason why modern applications run about the same perceived speed as their ancient counterparts did on ancient hardware - generally its because the programming involved is now built on layers of layers of abstracted frameworks.

For example, I run a few graphics-intensive games and they work fine, then I run a couple of not-so graphically intensive games that were written using XNA and the cooling fans come on full blast. I don't think its a coincidence that the 'easy to use' abstraction of XNA leads to overall inefficient use of my gfx card (and the power required to run it) where the better libraries that require better developer skills don't.

If MS is targeting efficiency, then we should see an improvement in speed as well as saving the planet from all those millions of PCs running these things.

Re:Megawatts worldwide

You mean "take all computers with IE _10_", which is not that much. IE 8, on the other hand, is a fucking cycle (and by extension, watt) hogging behemoth.

Yeah, but doesn't running windows consume a lot more power than running OSX or GNU/Linux? Especially with all that fancy aero stuff, etc, etc.
My laptop had windows out-of-the-box. With Linux I get abotu 25% more battery duration, which basically translates to 25% energy savings. Windows+IE pushed me the wrong way.

Disable Flash

Re:Disable Flash

[Anonymous Coward]

While using a rather under-powered atom netbook I quickly took interest in browser performance. On a cpu that slow you really notice which applications eat cpu power. Differences that are largely irrelevant on big multicore desktop CPUs.

Out of IE, Firefox, Chrome, and Opera the best result came from Firefox. Not because firefox is faster or more efficent, its because I could install adblock+ and noscript. (Without those addons Firefox was as bad as the rest)

Turns out that most modern webpages load gobs and gobs and gobs of scripts from dozens of different domains. Adblock cuts out the uselss ad serving ones and browser data abusing tracking ones. Noscript lets you whitelist only the ones you need out of the rest. The difference was really jaw dropping. Performance went from barely tolerable to pleasant (Well, as pleasant as can be on a netbook with a tiny trackpad, screen, and keyboard)

I think the problem is that most web sites waste your time with useless or downright abusive js.

That is quite a bit of power!

[bickerdyke]

The energy needed to brew a cup of tea is definitly NOT small compared to the energy that is available in your cellphone battery.

Re:That is quite a bit of power!

[xaxa]

Using this (so making five cups at once):

2.2kW * 3 minutes / 5 = 0.022kWh.

1W * 20 hours = 0.020kWh (the extra energy used by Chrome).

However, I think the whole thing's rubbish -- I don't constantly load websites, I load them once (which takes a few seconds -- or longer if it's IE), then spend time reading the page.

Re:That is quite a bit of power!

[bickerdyke]

Ok... so just assume that a typical cellphone battery has a capacity of 2000mAh and a voltage of 5V, then the power stored in it would be something around 0.01 kWh

So you would need the energy of TWO whole cellphone batteries to make a cup of tea.

The difference would be that browsing 20 hours with IE means that you have to go two charching cycles less within those 20 hours than with another browser.

Now we only would need to compare this to a typical number of recharching cycles for 20 hours nonstop-browsing.

But still, it's meaningless if it's only visible on dasktop machines and/or they don't know why IE uses less energy.

On my 35W laptop this means 3% power savings.

(my dupe comment on a dupe submission: http://slashdot.org/comments.pl?sid=3846941&cid=43962015 )

This article seems to wind down on the marketing effort. Whats news in that? I rather like this fact exposing instead of the shockshell courtroom cases.

Re:Theehee thats a bad comparison

[Anonymous Coward]

Actually heating with electricity is 100% efficient, if you don't take into account the production and transport of the electricity to your home. Of course those very same production and transport losses will also happen for the electricity you use to drive your computer (and if it's a laptop on battery power, you'll have to add the losses from the battery charging cycle to that), and are certainly not included in that 1W savings figure.

BTW, I'd expect the power requirement of the browser to be strongly dependent on the processor. Especially I strongly doubt that IE on the processor of your 35W laptop will save you 1W, even if your surfing behaviour happens to match exactly the test scenario.

And BTW, the meaningful number would not be the absolute wattage, but the relative one. If IE consumes 0.1W where FF consumes 1.1, that's a significant difference. If IE consumes 1000W where FF consumes 1001W, the difference is negligible. And yes, the first pair of numbers is ridiculously low, while the second pair is ridiculously high, but that's intentional, to make the point more clearly.

Finally, I'd bet FF with AdBlock and NoScript consumes less energy than IE without those.

Making tea isn't 100% efficient. The kettle doesn't magically remain at room temperature while heating the water to boiling point.

Microsoft failed to mention the amount of power wasted cleaning up malware infections brought about because IE is not able to block malware 'mouse over' attacks.

Re:On the other hand...

[gishzida]

When a user cannot compensate for bad design of a tool 'out of the box' it is time to get a different tool.

IE in all of its generations has been designed to hook into the OS first rather than protect the OS and the user first.

  IE has never been designed to actually block scripted behavior because MS has always believed that scripting behavior in all its forms is a "feature not a bug" and the plug-in architecture of IE [so far as I am aware] does not allow for the use of plug-ins like "no script" and "Ad Block Plus" therefore IE is always going to be a less secure tool than others which do.

Yes both Chrome and Firefox both are doing things that are frustrating [the number of crashes per day in FF is up!] ... BUT the important thing is every time I've had to clean up a problem on a client machine it is because the user was using IE exclusively. I have not used IE on my own machines [7 at last count] in atleast 6 years and have not had a malware infection via the browser on any of them during that period.

While I appreciate Microsoft's willingness to give me work to do in a lean economy, I'd rather it be in a less time and energy wasting manner... I hate telling people they are idiots because they trusted something they should not have. IE is an untrustworthy browser by design. Think if it this way: Would you hook your plumbing or electrical directly to the Internet without proper safeguards and disregarding standards? Would you let your car's manufacturer design the car in such a way that it will only allow you to use one brand of gasoline or oil or other after-market device or service? Would you use a browser tool that is always collecting data on you and your usage behavior and reporting it to the software vendor?

This all boils down to trusting Microsoft. Are you feeling lucky?

Do you *really* want to trust a chair throwing monkey boy who wants to sell you some poorly designed crapware so an old bastid like me can come in and fix it?

The day MS releases IE with a plug-in architecture that allows script blocking plug-ins and other security plug-ins designed to kill XSS, bad script behavior, and mouse over attacks will be the day I tell my clients it is safe to use...

[jamesh]

I use firefox on my laptop almost exclusively (I don't drink tea), but on terminal servers i'd much prefer users ran IE than firefox. Memory is cheap but lots of memory is expensive, and the stats of IE vs FF on a terminal server shows IE using hardly any resources while firefox consumes much more memory and cpu.

of course firefox is better so i'd expect it to use more power to better express it's awesomeness...

Re:No method?

[wonkey_monkey]

As with many Slashdot stories linking to news reports of scientific experiments, you may need to travel a whole two clicks away:

we installed three popular browsers, Google Chrome, Microsoft Internet Explorer, and Mozilla Firefox, on six new notebook and four desktop computers running Windows 8. We then measured the average power draw over one-second intervals for a six-minute period with each of the individual browsers open, for each of the ten most-visited websites in the U.S. In addition, we also measured power draw for both the Flash® and HTML5 versions of an online video, as well as the Fishbowl HTML5 benchmark.

Re:No method?

[realityimpaired]

Windows 8... That answers everything. Remember a year ago, when the browser creators were complaining, because Windows 8 wouldn't let them run their renderer natively, so they had to either take a CPU hit to run interpreted code, or use the Trident rendering engine?

I'd like to see the same test done on Windows 7...

1 Watt is HUGE on mobile!

[bemymonkey]

As I type this in Firefox, Lenovo's Power Manager is showing power usage of about 6W. 1W less would be a 17% decrease! With the 9-cell battery currently attached, that's a 2h20m jump in battery life.

Of course, I've already dropped FIrefox's power consumption significantly using Adblock, Noscript and so on, so it's unlikely I'll see a full Watt of improvement by switching to IE, but for others, this could be huge.

Re:1 Watt is HUGE on mobile!

[Anonymous Coward]

But how does it scale? Saving 0.7W-1.0W on a 37.8W as in the article might well translate as low as 0.0185W-0.026W, giving you an extra 3 minutes if you're lucky. That's also assuming that it IE doesn't draw more power in total - unfortunately the source cited in TFA wasn't available when I tried so the only numbers available are the "averages" with no explanation of what they're averaging over (if it's average during page load, for example, and IE takes twice as long to load then IE uses more power overall).

Re:1 Watt is HUGE on mobile!

[Anonymous Coward]

If it was a 1W decrease on your Lenovo.

By reading TFA you can find the link to original report and see that 1W is _average_ over different laptops. Seems like on newer ones they saw the difference of +-0.2W in favor of different browsers for different websites and ~1W is for older laptops with baseline draw of ~25W.

Re:1 Watt is HUGE on mobile!

[bemymonkey]

Hmmm, the chart seems pretty clear: Average power consumption over a set period of time displaying the web page (either including or not including the power spike during the page load - at those figures, I'm assuming it includes the spike unless the laptop is running dedicated graphics).

The PDF seems to confirm this (see 2.2.2) - 6 minute test for each page, including the load spike.

Re:1 Watt is HUGE on mobile!

[bemymonkey]

This is correct, of course... however: I've already decreased the average power usage of my system with idling Firefox from about 8W to 6W (no Flash, Noscript, GIFs set not to animate, Profile and Firefox itself entirely on RAMDisk to minimize disk access etc.). I'd assume optimizing the browser directly would be much more effective, so getting half of the power savings I'm able to reach with a few simple (albeit drastic) tweaks is entirely within the realm of reality, IMHO.

You may be right about that, but even then, someone who runs a bog standard Firefox or Chrome would see a benefit in battery life by switching to IE.

Not that I'm advocating switching to IE, of course... just saying Firefox and Chrome need to start focusing more on reducing power consumption.

Returning to IE

[Anonymous Coward]

Lately there have been a series of changes to Firefox that leads me to feel Mozilla has "jumped the shark". I don't know what it is, perhaps many of the Gnome programmers who supposedly abandoned that project have joined Mozilla, I don't know, but recently Moz have been stripping out features and making changes that at least on the surface have no reason.

I worry they have begun to believe their own hype and forgotten that's we use them for the power of customisation - the freedom the user has to utterly control their browsing experience. Lately, this seems to be better served by Microsoft. For example, there's an add-on (McAfee site Advisor) that I cannot for the life of me disable in Firefox but with IE, no problem. Browser and download history handling and cookie handling all appear to have much improved in IE, whereas in FF since v20, previously multiple options are being combined or stripped-out. Moz seem to be joing the "dumb-down" brigade and the anti-config zealots from Gnome-land. Some of the UI changes are just bonkers.

Getting used to IE is taking some work and there's a few things that are irritating, but right now it's a lot less irritating than whatever Firefox is morphing into. I'm still not sure, maybe I'll give the webkitted version of Opera a go (sad what happened there though).

I'vew been a true-blue (red?) Firefox user since day one and the recent developments are worrying, switching to another browser makes me feel sad but as I can't program I have to go where the functionality is because I can't fix it myself.

Test procedures

[Anonymous Coward]

Let's look at the test procedure in the actual report...

Measure the true root-mean squared (rms) current, power, and voltage for each UUT over a six (6)-
minute period at 1Hz (averaging over 1s period) for the following test conditions:
a) Baseline: No browsers or other windows open
i) First perform a preliminary measurement of power draw in this mode for the UUT, to
ensure that the lowest suitable current range has been selected on the power meter to
maximize measurement accuracy
(1) Record the current range selected for testing the UUT
(2) Record at least 6 minutes of ‘Baseline’ UUT operation with no browsers.
(3) Move the mouse/trackpad once a minute to prevent the unit from going idle
b) Static Website Test: Three different browsers (Internet Explorer, Google Chrome, and Mozilla
Firefox) will be used. Each browser will be tested for the Top 10 U.S. websites as of March 25,
2013 (listed below, from Alexa 2013). The UUT will then be rebooted after all ten websites have
been tested. In all cases, the browser will have two ‘background tabs’ open to
cse.fraunhofer.org and cfvsolar.com, both static landing pages.
i) Each browser will be directed to the following websites, with all cookies accepted. Data
logging will begin immediately when changing the target website to capture transitional
power draw.
(1) Google.com
(2) Yahoo.com
(3) Live.com
(4) Youtube.com
(5) Facebook.com
(6) Wikipedia.org
(7) Ebay.com
(8) Amazon.com
(9) Craigslist.org
(10)Bing.com
ii) Record all power, current, and voltage measurements in a database. Each test will take
place for at least 6 minutes.
iii) Move the mouse/trackpad once a minute to prevent the unit from going idle

Notice the "at least 6 minutes" part...
So if we change sites every 6 minutes with one browser and every 30 minutes with another, that's still perfectly valid.

And then this gem:

In addition, at the request of Microsoft we set the JavaScript timer frequency to “conserve power” in
the Windows power options. We found, however, that the default Javascript time frequency for all
computers tested was set to “maximum performance.” We did not investigate the impact of this setting
upon browser power draw.

[plankrwf]

In true /. tradition, I did not read the article. So perhaps the article contradicts me, but just bases upon the summery I could give an alternative explanation:
It could have been that the following two things are true:
1. IE is terrible in use. It is that horrible to work with that an average person browsing the web for 20 hours with IE reads only half the pages compared to an average person using Chrome or Firefox.
2. IE is terrible in powermanagement. Within that 20 hour period, it will use almost the same amount of energy to load and display the pages as Chrome and Firefox use to load and display double that number of pages. Compared to - say - Firefox this is partly true because the average Firefox user reads less ads (through extensions such as add-blockers) and hence less information had to be downloaded, and less flashy ads have to be shown.

No energy saving ...yet

[ColdCat]

The paper is clear there is no conclusion from those tests. And as the tests were paid by Microsoft If there was something really significant in favour of IE we will read it everywhere.

Due to the very limited number of test conditions, we cannot draw robust conclusions about differences in power draw among browsers running Flash® and HTML5. We recommend conducting additional testing of a larger set of Flash® and HTML5 websites to draw more robust conclusions about how these technologies impact computer power draw.

It's good to start some energy efficiency ranking. Windows 8 (all tests are on that platform) have some very nice feature to helps developer on power consumption. My guesses is that no-one is using them as you need Win8 specific code but if somebody like microsoft try to MAYBE we could see some real differences.

And more complex media experiences, delivered by sites using Flash or HTML5, appear to burn even more energy, with heavy HTML5 and Flash sites causing an increase in power draw of up to 8W or 9W (effectively adding 50 percent to the machine’s power draw)"

So maybe IE can make more power-efficient use of Win8 when playing YouTube videos? Not really a surprise...
Put noscript, adblock etc. into Ffox and save! (Also on bandwidth..)

Would have been nice to have seen Fraunhofer (who conducted the survey) try and retain some shred of dignity by comparing performance on other platforms.
How about Safari on PC & MAC? Chrome & F'fox on Linux also?
Maybe because IE only runs natively on Windows?

explorer.exe

[Anonymous Coward]

Was the test fair? i.e. did they kill explorer.exe when testing the other browser(s)? oh wait...

WHY?

[Anonymous Coward]

You know WHY they can say this?

ALL WINDOWS COMPUTERS ARE RUNNING 'IE'. ALL OF THEM.

It's the main process IN windows. it IS ie. explorer.

Call it whatever you want. The shell. The UI. It's ie.

That's why it was always stupid they tried to make microsoft 'unbundle' ie... It's not really a seperate package.

I run browser on other operating system

[stasike]

OK. I could save one watt by running IE instead of [insert your favorite browser here]. But then I would have to run it on Windows, and install anti-mallware, anti-virus and other anti-CPU measures.
I think I am much better off running a less efficient browser on Linux, even with a memory hog called KDE 4 running the whole show.

Re:Less Power? Easy

[kramulous]

Yes, I have done it. On my 46" LED Samsung TV (late 2010 model?), a majority black screen draws 22W while a white screen will draw 58W.

Regarding your black on white comment, I spend about 10 hours a day, 6 days a week for the last 15 years looking at gedit with an 'oblivion' font&color setting. I find it quite pleasing to look at (particularly when staring at i's, j's and k's in loops) compared to black on white, which I can sometimes lose focus, line, on.

Just sayin'. That's all.

Is the power saving feature PATENTED ??

[Anonymous Coward]

Power saving, no matter how little, is _STILL_ power saving

And in our world where fossil fuels are being burnt up to generate electricity, every single watt counts

I like to know one thing --- is the IE's "power saving feature", no matter it's clever code tweaking or whatever type of black magic they use, has Microsoft PATENTED it ?

If M$ hasn't patented it, then it would do the world a lot of good if M$ shares their "power saving code" with all, just to make this world we live that little bit nicer

What say you?

Re:Is the power saving feature PATENTED ??

[crutchy]

if there is any clever code in IE, microsoft probably stole it from open source

and the only place where every single watt counts is on your electricity bill, and not only because it is probably one of the few places where individual watts are actually counted

Re:Is the power saving feature PATENTED ??

[LifesABeach]

I see two problems here. 1, you responded to an AC; you've replied to someone that knows they're wrong. 2, who ever modded you down was most likely the AC. The AC has already demonstrated their lack of insight that they will defend to the point of self destruction.

Re:Is the power saving feature PATENTED ??

[Stewie241]

I somehow doubt they really did anything to save power. It seems far more likely that they had a lab setup and did measurements and found that IE used less power than the other browsers that they tested and decided to market it.

The summary does a disservice by comparing the power usage to that required to make a cup of tea. If you read the article, it says "Laptops use about 14.7 Watts when idling. Firing up a browser adds another one or two Watts to this, depending which sites are browsed, and which browser you are using, Fraunhofer found. On desktop PCs, browsers add the same amount to the energy draw – but the baseline is around 37.8W."

So what we're talking about for a laptop is a power savings of about 6-7% when idling.

Power savings in computing for things like web browsers is not about saving the world - it is about allowing you to use your device longer. If you can surf for an extra ten minutes by using IE vs. say Google Chrome then that is actually a somewhat interesting differentiator.

Re:Is the power saving feature PATENTED ??

[datavirtue]

I want scientific proof that not starting IE and running Chrome is using more energy.

The question remaining, however, is how much of that is hidden by running Windows? In other words, do the same thing with Linux (GNOME, KDE, etc) and Mac OSX. Does it really make a difference? Or is Windows merely hiding the extra usage by always having that usage included in the OS? Of course, don't expect Microsoft to fund such a study.

Re:Is the power saving feature PATENTED ??

[Stewie241]

Well, the study was about browsers and not operating systems. I sort of assumed they tested all browsers on Windows in which case that is a controlled variable.

I'm sure they would sponsor a study looking at power usage of Linux vs. Windows vs. OS X. You probably won't see the results of their work unless it is in their favour, and you probably won't see the results of their work w.r.t. desktop Linux as it doesn't have the mindshare that would make it worthwhile to waste advertising space on (few know what Linux actually is, fewer would consider using it, and fewer still would consider using it, would make a decision based on power usage, and would trust a study funded by Microsoft to base a decision on). I say all this as a Linux/OS X user.

Re:Is the power saving feature PATENTED ??

[Anonymous Coward]

Well, they did at least one thing to save power:

In addition, at the request of Microsoft we set the JavaScript timer frequency to âoeconserve powerâ in
the Windows power options. We found, however, that the default Javascript time frequency for all
computers tested was set to âoemaximum performance.â We did not investigate the impact of this setting
upon browser power draw.

I guess this setting only applies to IE, and sure enough they "did not investigate".

Note also that "average" is not very useful when range of baseline draw is from 9.76 to 22.65 watt and difference in power usage from site to site and from laptop to laptop ranges from 2-3W to 0.1-0.5W

This is not about "how do I save an hour of battery life?", investigating that JS performance setting and dynamic content blocking effect on power use would tell you more -check out a dude getting his FF power usage from 8 to 6W using NoScript/AdBlock etc. down there in the comments. This is about "what numbers can we show to make IE look better?"

Re:Is the power saving feature PATENTED ??

[g0bshiTe]

My guess is that "power saving code" is the fact that half the time the browser doesn't work properly and 45 minutes of that hour is spent with the windows suspended in (Not Responding) mode.

Re:Is the power saving feature PATENTED ??

[g0bshiTe]

I agree, but how does that translate to my using IE allowing me to actually watch the last 15 minutes of that DVD while on an airplane?

True, the study was about browsers on Windows. However, given that IE is integrated into Windows you need to also have a control variable for Windows too.

Re:Is the power saving feature PATENTED ??

[cheater512]

Shock. You are telling me that they oversimplified a topic like computer power consumption?

Operating system comparison would provide significantly higher power usage differences.
As would the presence or absence of Flash and ad blockers.

Hell chances are there would be significant differences depending on if the laptop was switched on 30 seconds previously to an hour previously.

Battery power

[jibjibjib]

On a laptop or tablet, one watt is a lot of power to waste. But of course it looks small when you compare it to an irrelevant but very energy-intensive task and add some anti-Microsoft flamebait.

Re:Battery power

[Anonymous Coward]

I refuse to read this lame-o study, but, like others, will comment anyway. It seems to be the /. way.

The 1 watt "savings" has got to be the saving relative to a specific setup. I can't believe that you can get 1W savings on a 100W desktop system, and also get 1W on a laptop that may be consuming 25W on average. Seriously, c'mon. If that were the case, it *would* be significant at some point.

Re:Battery power

[Anonymous Coward]

If you really wanted to save power (and bandwidth!) on your laptop, you'd simply install ad, flash, and script blockers. Especially ad.

Apple are doing this as well

[icb1000]

One of the exciting new features of Safari in Mac OS X announced at the WWDC keynote yesterday was the power savings when web browsing as compared to Chrome & FireFox.

Power savings in terms of real-world power consumption isnt the relevant factor here, rather it is the impact in laptop battery life that power savings can have

Microsoft shouldn't be proud of that

[Anonymous Coward]

I'd expect a bigger difference, it's a third party vs. inhouse product, Microsoft has all the means to give IE advantages over the competition. So, no, I am not impressed by Microsoft.

Where they testing this one Windows machines

[pecosdave]

Meaning that IE was running on the test machines regardless of browser being tested, but the same wasn't true in inverse?

Hardly seems fair to me.

When IE first started getting forcefully integrated in the latter days of 95, even more so in the 98 days, one of the first things I would do is do every hack and trick I could find (usually available in handy "lite" programs) to remove IE from the background when you weren't using it. It was a major undeniable performance boost on those machines of the day. I'm guessing we're still dealing with a remnant of that.

Huge difference with OLED

Page swapping

[Anonymous Coward]

It could be that Microsoft's developers found some tricks to reduce IE's page swapping (as in virtual memory pages, not HTML pages) by more careful management of heap memory usage, or perhaps reining in some of the tricks (opening dozens of TCP connections to each site) that may reduce presentation latency in a few edge cases but waste disproportional CPU cycles.

It's the same with browser speed ...

[stevez67]

... They all brag about saving a ms here and a ms there, making a big marketing deal out of a browser taking one blink or two blinks of an eye to display a page.

Even Better on Linux!

[Jah-Wren Ryel]

What the press release totally left out was that the power savings of running IE on Linux is 100% compared to running firefox on linux. I don't understand why MS wouldn't mention that in their own press release - I mean, how often does MS beat anybody on linux systems?

Saving 18% is HUGE!

[elabs]

This year battery life is he #1 stat to follow. That's what everyone is boasting now. We're past the GHzs and GBs ever since Moore's law failed us. If your browser can make your battery last 18% longer then you're clearly ahead of the pack.

Re:Notebooks

[VortexCortex]

Consider how much energy we would save as a species if IE never existed. I remember all the wasted time debugging and breaking my code to work with IE6. I still do have to write code that works in EVERY OTHER BROWSER without change, and then consistently does not work in IE, and requires additional effort to create. Consider that continuing to use IE means every web business wastes time making code that specifically panders to IE's broken rendering and javascript environments. I'm sorry. I remember the years of abuse. With their lack of adoption of WebGL I see only more abuse in the future. Screw IE.

Bloated web pages are the real power wasters

[linebackn]

Of course, I've already dropped FIrefox's power consumption significantly using Adblock, Noscript and so on, so it's unlikely I'll see a full Watt of improvement by switching to IE, but for others, this could be huge.

And you have found the real power guzzling culprit!

Browsers wouldn't have to waste so much power if they didn't have to spend so much time processing crap rather than just displaying your content. On some web sites I have managed to vastly increase the speed and responsiveness of the sites just by blocking certain "analytics" scripts. And only the insane would browse the modern web without Adblock. Less processing time translates in to power savings, and which browser someone is using is mostly irrelevant since they all have to process the same junk.

If a large company really wanted to save power and increase productivity, they would install such blockers on clients or a central proxy. Or better yet, demand sites embed less of this crap to start with.

* Debian Wheezy, YMMV

Putting it into perspective

[Anonymous Coward]

it's about one Watt when browsing. Browsing for 20 hours at this rate, the IE user would save enough power to make a cup of tea, compared with Firefox and Chrome users.

Putting that into perspective, that savings means that /. readers could power a small city if we all switched (back) to IE.

Re:Putting it into perspective

[Anonymous Coward]

Sure, with the fine print reading:
* Assuming everyone runs Windows 8 with IE 10
** With IE's JS engine switched to power conserving mode in Windows control panel ("We found, however, that the default Javascript time frequency for all
computers tested was set to âoemaximum performance.â We did not investigate the impact of this setting upon browser power draw." as the fine paper states)
*** On certain models of laptops and desktops and for certain sites
**** Assuming we browse the net all day long
***** For a really small town of ~1000 conservative families and no industry at all.

And consider what savings we could have if we'd all switch to Damn Small Linux and Lynx for browsing!

Yes but how much power does Windows 8 use...

[skiman1979]

How much power does Windows 8 use compared to other operating systems? Perhaps you'll save enough money to make 2 cups of tea per week, but is that savings negated by running Windows 8 with both the Metro UI and the "desktop" mode with a separate version of IE in both modes? Compare that to Safari on OS X or Firefox/Chromium on Linux (gnome 3 vs fluxbox vs xmonad vs KDE...)

I mean if we're just looking at power consumption here...

do less, use less

[xcix]

Maybe it's the lack of WebGL support, IE does not need to use computation power to render the pretties. Or maybe it's the lack of support for modern Web standards in general. "Choose my app! it does uses the less power! It does one single thing turns off the lights in your monitor!"
