Gaming Computers Offer Huge, Untapped Energy Savings Potential
Required Snark writes: According to Phys.org, a study by Evan Mills at Berkeley Lab shows that "gamers can achieve energy savings of more than 75 percent by changing some settings and swapping out some components, while also improving reliability and performance" because "your average gaming computer is like three refrigerators." Gaming computers represent only 2.5 percent of the global installed personal computer (PC) base but account for 20 percent of the energy use. Mills estimated that gaming computers consumed 75 TWh of electricity globally in 2012, or $10 billion, and projects that will double by 2020 given current sales rates and without efficiency improvements. Potential estimated savings of $18 billion per year globally by 2020, or 120 terawatt hours (TWh) are possible. Mills started the site GreeningtheBeast.org.

So I should swap out my video card to save a little power, drop a few frames and die a virtual death? I think they have their priorities backwards.

Wouldn't it be easier to TURN OFF the gaming computer when you're not using it?
If you read or even browse the paper, all he really says is if you use newer components, they are more energy efficient. Which is like well, pretty much everything else on the damn planet.
Power saving settings on computers are super annoying. I work for a company whose software is ran in the cloud and the dang power saving settings on network cards make our program freeze in about 2 minutes of inactivity to save power annoying as heck to walk non-technical people through changing their windows power settings.
Aside from the GPU and CPU, which these days down-clock themselves automatically anyway to save energy and reduce noise, modern gaming rigs are just the same as any other PC. If anything, they are more likely to sport SSD drives than HDD and variable speed fans as well.
From a quick scan of the PDF, it looks like the initiative is concerned with "vintage" gaming rigs that don't necessarily feature what I just said. So it seems that it's a problem that will "solve itself" as time passes. We just need even more demanding games to push the need to upgrade!
Newer hardware is almost always more power efficient. The question is whether or not I have $1000 laying around to buy new equipment. That money is way more than I spend on electricity to run my inefficient old stuff.
This is no different than saying "we could save x brazillion gas/dollars/whatever if everyone would simply just buy a new electric vehicle. Don't worry, you can get almost the same performance if you choose carefully. Like a nice Telsa." Yeah...

1) Don't care. Seriously. I pay for the power, if it gets more expensive, I pay for more units of electricity.
2) I don't go and blow a couple grand on PC components to have to worry about S3, S6 and other sleep states effect when recovering a power rig.
3) A great way to start the conversation is calling people's gaming computers "the beast" and suggesting someone should "green" anything. (/sarcasm)
4) greening the beast only works with no preceding subdomain (like www.) www.greeningthebeast.org fails
5) A google site? Seriously? Welcome to geocities in 2015.
6) Did this site publish a "market survey"? Really? Its a massive spreadsheet that is pretty much unexplained and someone expects gamers to make use of this? I've got experience in statistics and finance from my day job and some of this thing is still hieroglyphics to me.
6.5) Did I mention, I don't care about greening when it comes to my gaming rig? I think I did.
They go by nameplate component watt requirements, installed PSU, and watt per GHz instead of performance
I used the newer video cards power improvements as one of the reasons to replace an older card*. The other reason for the upgrade was so I could play more of the new games coming out on Linux. I didn't factor in that I would spend more time gaming though...
*Replaced a Radeon HD 3870 for an Geforce 750 Ti.

How is it possible to take 20 pages to say so little that is actually meaningful? It basically boils down to "newer and/or lower performance components draw less power". No shit, Sherlock.
It's also rather misinformed when it comes to the availability of power-consumption information for gaming PC components. My current PC is a self-built gaming PC and I can assure you that when I was putting it together, power consumption information was absolutely something I looked at, because it affected my choice of PSU. And if you go to the manufacturers' websites, power consumption information is usually available upfront. If it's not, or if you want to know how it varies depending on loads, then there are any number of testing, benchmarking and review sites just a google search away.
There is probably an interesting article that could be written about minimising power consumption in a gaming PC, but it's not this one. In reality, power consumption is one aspect of a sensitive series of trade-offs. On graphics cards, for instance, you get get the same brute-force performance from AMD cards as you can from Nvidia cards at (usually) a much lower price - but the trade-off comes in heat and power consumption. So you can base your decision on a balance between how much you care about the up-front purchase costs of the card, vs ongoing power costs, potentially the cost of a new PSU and the noise/discomfort factor of having something that burns with the heat of a billion fiery suns in your PC. Most people building gaming PCs are not blind to this stuff.
The article reads like a lightweight piece of political advocacy for more regulation, trying to solve a problem which increasingly doesn't exist (the general trend over time is towards more power-efficient components and electricity prices act as a further restraint). So the author can, to be blunt, fuck right off.
How about we charge people according to the electricity they use?
That way, people can weigh what's important to them. If I want to work an extra little bit each day so I can make more money to spend on things like electricity for my gaming computer, I can.
I have this friend, Adam Smith, who I believe has explained it all pretty thoroughly. It's not a perfect system, by any means, but it's better than most, and pretty practical.

and a choice quote FTA
"One problem the authors found was an immense variation in the nameplate power; for example, graphics processors ranged from 60 to 500 watts."
where can I find me one of these 500W GPUs?
Everyone quick, "upgrade" your gaming rig to a quad-core intel Atom with built-in GPU!
I am pretty certain the person who spent thousands on a top end gaming rig does not particularly care about saving $126 over the course of three years.
But point out that besides saving him electricity, that the better power supply is less likely to fail and will scream less, and he's interested again.
A gold rated E80+ power supply is less likely to quit.

Racing drivers can achieve energy savings of more than 75% by swapping out some components and driving more slowly around the track. This will improve reliability and efficiency!

Where I live, three months of the year we need our central air conditioning. The remainder of the year we either need a small amount of heating, or a LOT of heating. Having my gaming machine add to the heat of the house is just a bonus. My TV providing 700W of heat? Bonus! Of course, the cost of electrical heat is higher than natural gas heat, but that heat pushed out from the computer reduces the total heat I need from natural gas. A bit of lost efficiency ($/but) yes, but you cannot consider it waste heat for most of the year.
Oh, and I upgrade on a 3 or 4 year cycle, so there is ongoing power efficiency gains, but there is absolutely no way that spending $1000s every 3 years will balance out the "savings" in lost electricity. In terms of effect on the environment, where I live the only fossil fuel used to generate electricity is natural gas, and that represents 15% of electrical generation.

I'm not usually one to be the person to call out the study, but as soon as I saw the test system for efficiency using a G3258 while performance remained consistent from the original system which was equipped with a 4820K I knew something was wrong. Their entire gaming benchmark suite consisted of Unigen Heaven which is specifically designed to test GPU performance excluding external factors like a CPU holding things back.
They need to redo the test and show the same performance scaling in real world gaming scenarios if they want gamers to take them seriously while still making power conscious decisions.
Although it's not perfect, money is a decent proxy for environmental harm.* So, if a $100 upgrade will save you $200 in electricity over its lifetime, then the upgrade will probably do more environmental good than harm. However, if a $500 upgrade will save you $100 in electricity, then you're probably doing more harm than good.
* At least for normal consumer goods, the price _roughly_ reflects the amount of energy and resources to manufacture the good, which roughly reflects the environmental harm. It's by no means a perfect metric, but it's a start. Some goods clearly do not fit this model. For example, a painting costs almost no resources to produce but can sell for a high price. Some computer parts are similar. For example, sometimes identical graphics cards are deliberately crippled (lower clock speed, parts of the processor disabled, etc.) just to create different price points. Both cards have the same environmental cost to produce but can have very different sale prices. However, that means the environmental cost is best represented by the cost of the _cheapest_ version. So maybe the aforementioned $500 upgrade really costs $50 to produce and thus has a positive environmental impact.
(Totally off topic: I wonder about the environmental impact of moving to cities. Say you move to a city, sell your car, etc. but your income remains constant; you instead spend money on a new TV, more beef for dinner, etc. Then it's not obvious to me that you're having a significant, positive environmental impact.)
A huge energy saving could be made if this guy just fucking dies.
His numbers are way off. First a gaming computer is not "three refrigerators." A fridge/freezer combo uses like 400-800 watts when spun up depending on size and if it is frostless or not. Your typical reasonably high end gaming computer (high end quad core processor, single high end GPU) uses in the 300-400 watt range when fully spun up. There are, of course, higher end systems but they are not common as they cost a lot, for not a ton of gain.
Well the idea that there are tons of components or settings that'll just tank energy use is stupid. In terms of settings, ya those are default. By default a system will put its processor and GPU in to an idle state when not heavily loaded, and indeed most systems draw 90 watts or less when idle. In terms of componentry, there really isn't a ton of room for gain.
Like with PSUs. Any reasonable quality PSU that you might see in a gamer build is at least 80% efficient, and usually more like 85%. Go all the way to the high end, which many gamers already do, and you are only pushing 90-92% max. A gain, sure, but not much. If a system draws 300 watts DC going from an 85% (bronze) PSU to a 92% (platinum) PSU is the difference between 350 and 326 watts at the wall.
Then there's things like GPUs and CPUs. Well guess what? A give one is as efficient as it can be at a given performance level. There aren't the better and worse ones. You can't buy the efficient model GTX 980 and the inefficient model. They are the same. You can swap one kind of component for another and maybe gain efficiency. Like you can swap an AMD 390X for an nVidia GTX 980Ti and that'll use less power, but what if you want the AMD card?
Also there's the issue that usually the new ones are more efficient than older ones. Fair enough but in addition to the cost of upgrading that ignores the energy cost of producing the cards. Suggesting that everyone buy the newest shit all the time is not realistic, or energy efficient (a lot of our energy use goes in to making things).
This guy just doesn't know anything about computers. He's convinced that there's these vast optimizations that could happen, if only people wanted it. Not really the case.
Sounds good, where do I pick up my Green Gaming subsidy for the new hardware?
Murphey's fighting Occam, and we're in the stands.
Guy doesn't know anything about what he's talking about.
For one there is the newer thing as you note. Yes, newer stuff is more efficient. At a given performance target (FPS for a given scene complexity, number of MFlops, whatever) newer hardware is better than older stuff. Ok, fine but cost of always upgrading aside (something gamers do more than most people) there is the issue of energy of production. A large amount of human energy use goes in to making the stuff we use. If you want to save energy, a big part of it is buying less shit, trying to make stuff last longer. You don't see that energy cost directly, it is rolled in to the product, but it is very real.
Then there is the fact that, as you note, gamers tend to use better components anyhow. Like the PSU thing. The higher end the gamer, the better the PSU they tend to want and thus the more efficient it tends to be. I personally have an 80 Plus Platinum unit in my system because it was the highest efficiency, best built, longest lasting unit I could get my hands on. It was expensive, way more than most people are willing to pay for a PSU, but as a crazy gamer I'm ok with that.
Guy is just an idiot.
Puns aside about consoles insomnia. Wasting $100s of dollars of you power bill every year is not a serious concern for the video game industry. In 2008 the NRDC, the US EPA with their EnergyStarWalmart beat the console industry about the head and neck and the video game industry managed to sandbag any regulation that even a GE or Sylvania could not for lighting. The reason is simple sloth and incompetence. Simply put the problem is not energy used during game play , but the lack of a meaningful sleep mode. This lack of sleep mode is driven by poor APIs to book mark game status and put the console into sleep mode. The other energy driver is the console companies instant on collecting detailed data of how you use your device and uploading it when you are not playing plus forcing add and other "content" down to your console when it should be sleeping.
Power consumption is really only a problem when my gaming computer is awake and that's not that often. The power consumption when sleeping is minimal and not worth worrying about. Even if I were to run my gaming PC 24x7 and never have it sleep, it only costs about $5 / month and I don't really care about that. If we were talking about a major household appliance then sure, I care about its power consumption but not when it comes to my gaming computer.
That sounds like something that could be applied to a lot of existing hardware quickly, and should logically have its own heading, but I didn't see it in a very quick skim of the PDF. What kind of settings are they talking about?
PHEM - party like it's 1997-2003!
I didn't see it either. If you find it, I'd love to know.
1) A PS3 is not a gaming PC, which is what we are talking about.
2) PCs go in to idle states BY DEFAULT, you have to work to turn them off. My PC, an exceptionally high powered one, idles at about 90 watts. A more normal PC idles at 50 or so. Not turning off, not suspending, not doing anything special. The processors normal C-states and throttling which are enabled by default.
3) You can turn your PC off. I do.

It's the classical "iron triangle" (aka constraint triangle): you have three sides to a triangle; performance, power consumption, and cost. Pick any two that you want to be favorable, and the more favorable you make them, the more unfavorable the third will be.
Nvidia and AMD discrete cards for desktops are designed to tug on the performance and cost sides as much as possible, leaving only a passing thought for power savings. Granted, it's reasonably efficient when in standby and not that bad at idle, but it's horrendous under load.
If you want a GPU that's less horrendous under load, without compromising on performance, expect to pay a LOT more for it. And in most cases, because of market forces, you're also going to take at least a slight performance hit.
For instance, the GTX 980M is way more power efficient than the GTX 980 desktop card, because of the design constraints of laptops. It's effectively power efficient by design because of the form factor. But the performance is notably worse, and buying a laptop that has one is way more expensive than buying a desktop with "good enough" components (some kind of recent i7 and 8GB or more memory) and a GTX 980 or even 980 Ti.
We're not going to see chips that maintain the desired performance level (the one constraint that most people are unwilling to compromise on if they're owning a "real" gaming PC) while saving on energy, unless the cost goes so high that only the most elite can afford it.
We see similar problems in the car market, too. The Prius and Prius C are relatively inexpensive (the C is very inexpensive), great fuel efficiency - though not as good as an EV or PHEV - but the performance is terrible. The Tesla Model S achieves amazing performance, range, and efficiency in a pure EV package, but no "commoner" can afford it, only the upper crust. Then there are loads and loads of cars that are not particularly efficient, very cheap, and have serviceable performance.
Who's paying for the more expensive chips that give us the same performance we're already getting but with less energy consumption? The gamer? Why would they do that?
P.S. - Before you accuse me of not thinking of "the greater good", I *drive* a Prius C. I bet the same scientists who wrote this paper drive conventional SUVs.
Although this isn't high-end gaming, I noticed a couple of interesting power measurements at work:
My 10-year old Dell desktop, running Windows XP and no anti-virus (AV) boots ~25% faster and draws ~30% less power overall (idle & taxed with performance software) than the new guy's new Dell laptop that runs Windows 7 & Norton AV. We can both run all the same software effectively (albeit all my versions are several years older), except that I have a different brand of PCB design software than he; I'm guessing if I ran his PCB program my computer might drag.
Also, my ball mouse draws 1/5 the power that his optical mouse does! That was a surprise, too. I wonder whether a ball mouse is a better idea for laptop users when it comes to extending battery life.
My single CRT drew 1/3 more power than an LCD. My new, micromanaging, pointy-haired boss forced me to toss it(?), and replace it with two LCD widescreens. So now I draw 50% MORE than my single CRT did. My productivity is unchanged. Sigh...
Did you know, if you buy a solar panel, attach it to a 12v regulator, buy multiple batteries and operate on solar power only, you can significantly reduce the power your PC consumes and pay less in hydro? You'll only need to charge it on grid during colder seasons when there's less sun and more cloud!
We can always spend more money to consume less of a resource. You can buy a small car instead of a truck too. It doesn't always work. Sometimes we need / want a truck for the things we do.
Sometimes I need 8 cores. However, I do let it balance power, reduce clock speed when not in full use.
A larger power supply consuming more power is a common layman's misconception.
A double-the-load power supply being more efficient is a common gamer's misconception that came from a rule of thumb that is no longer true.
For a power supply to get a 80+ gold rating, it must be independently tested to have at least 90% efficiency at 50% load and 87% efficiency at 20% and 100% load. In the past, when I searched for the actual efficiency curves of Seasonic power supplies I was shopping for, I found that in reality, it's a plateau with less than 1% dropoff until almost reaching 100%.
However, the sub-20% load mark is a different story. There is no efficiency requirement here, and most power supplies have very bad efficiency below 20% load. An overly large power supply can cause your idle usage to fall under the 20% mark. If your max load is 500W and idle is 150W, then a 1200W supply is probably at less than 50% efficient at idle (from most efficiency curves I've seen - ymmv), and that's 150W lost. In this case, I would recommend a 600W or 650W power supply. Definitely nothing over 750W.
So, we can either lower our framerate (which is already below 60 fps because of shitty ports) or buy more efficient hardware.
More efficient hardware will cost hundreds of dollars. This hardware will only get maybe 30 % better efficiency (or maybe 50 watts) than the stuff i currently have, and will last me 2 years at most.
If i left my computer running at full usage for 2 years, i would save at most 90$ worth of electricity. My game playing experience would not be any better either.
This is a very very extreme case too. I rarely play games for more than an hour a day anyway, so saving just a few dollars on electricity when spending 300$ on new hardware for the exact same experience is not worth it. It would be much better to buy LED lights.
