New submitter MBAFK writes "My coworker Geoff and I have been taking power meters home to see what the true cost of PC gaming is. Not just the outlay for hardware and software, but what the day-to-day costs really are. If you assume a 20 hour a week habit, and using $0.11 a KWH, actually playing costs Geoff $30.83 a year. If Geoff turns his PC off when he is not using it, he could save $66 a year."

Some idiot in Cali was complaining about his power rates. Mine are a third of what his are. He said that I have no right to complain. Mine are still high. Is he right?

What do you _mean_ by "too high"? (3, Insightful)

Anonymous Coward | more than 2 years ago | (#40142007)

Everyone always has a right to complain, but some people's complaints are silly and make me think they're idiots, or to put it nicely, their personality is generously infused with irony.

I can't say whether or not you're an idiot, though, because you merely said "too high" rather than explaining why you think your rates are "too high" -- you might have good reasons which expose corruption in your state's PRC, or you might have amazingly stupid and arrogant reasons, based on arbitrarily saying things without thinking hard about them, and where even those shallow thoughts are founded completely on a lack of information and evidence.

So who knows? You didn't even give numbers for "too high" (which wouldn't tell the whole story either, but would probably bias me one way or the other).

Running PC games can easily take 300-500W with a high-end graphics card. Posting on Facebook probably uses 30-50W on a modern desktop PC (plus whatever the monitor uses in both cases).

Actually typical modern desktop uses more like 60-150 W while browsing. My desktop (not that new Phenom II X4 rig) uses about 90 W (computer itself only) when idling. Maybe a new Core i3 could get to level of 50 W or maybe even 30 W, but that's not something everyone has around here. There are not that many Phenoms either but something older. Laptops could easily be in, lets say 20-40 W category. But I'll wait when some Rapsberry Pi owner tells his numbers.

Btw that desktop of mine uses around 250 W while playing Minecraft. Some other 3D games I tried used similar amounts of power.

Actual data that I've taken from my home server:

Idle: 53W.

One core at 100%: 73W

Both cores at 100%: 93W

These are measured at the AC plug.

I didn't measure differentials for optical disc activity (DVD burner was idle when testing) or for high levels of disc activity (disc was spinning, but not being actively used during testing) but the thing that stands out to me is that the background power usage of this machine is larger than the differential caused by CPU utilization.

I also can't help but notice that CPU clock scaling doesn't seem to contribute to energy savings on this particular machine, else the differential between idle and 1 core busy would be larger than the differential between 1 core and 2 cores busy, owing to the fact that the cores are clocked together.

The machine is an Athlon X2, 2600 MHz. The motherboard has an integrated nVidia GPU. 1.5 TB Seagate HDD (7200 RPM), cheap-ass Optiarc DVD burner (don't get one, seriously), 6 GiB of RAM. Power supply is a 450W Corsair.

Yes, but the article was specifically about saving money by turning your computer off when you're not using it. Sure, a high-end gaming system is going to draw more power even when idle than a crappy underpowered and outdated system (like my mom's) but I don't think the difference is going to be significant enough to make the claim that this is something that will specifically help PC gamers. Everyone can save money by turning the machine off when not in use, whether you're a gamer or not. (Although for my money -- pun intended -- the savings isn't enough to justify the annoyance in having to boot the machine every time I sit down to use it. I do put mine into sleep mode, but that's as far as I'm willing to go.)

There are definitely some offenders out there; but contemporary GPUs are increasingly good at cutting back when they aren't needed. Laptop OEMs won't touch an architecture if it will utterly toast the battery just to dump the desktop to the screen, and desktop cards(while their maximum draw seems to edge ever upward) have inherited a similarly parsimonious lower end.

Sleep on a modern machine is pretty damn good. On my main gaming PC if you turn off the monitor and sleep the system it uses 3.18 watts. If you turn the machine off rather than sleep you use 2.92 watts.

Current generation of video cards, even the high end, draw maybe 2-3 watts when idle. The Ivy Bridge CPUs are 77 Watt TDP rated and idle they consume peanuts. With a good PSU and SSD, I seriously doubt these systems will draw more power idle than a crappy outdated system.

gmack (197796) | more than 2 years ago | (#40143777)

It really would have been helpful to know what hardware you tested on. I get that the CPU and GPU both likely downclocked when idle but Does it have a HD that spins slower (WD greendrive and friends) when not in use? Does it have an SSD card? What monitor did it have? Was it an LED backlight or one of the older ones that use more power?

I also can't imagine anyone not setting their monitor to power off when idle.

Re:PC gaming? (-1)

Sure, if your PC sucks ass. 5760x1080 on 3 screens with SLI FTW (900 watts). Real gaming costs $103/year if you're cutting yourself back to 20 hours/week.

Sloppy (14984) | more than 2 years ago | (#40142125)

If your mother only uses her computer for Facebook and Turbotax but draws 100W while idle, then your mother needs building advice. Nudge her into moving to Ivy Bridge Core i3 (and use the integrated graphics; don't add graphics card) when they come out in a couple months.

(Actually if that's all she does, maybe even an Atom or Bobcat system will be enough, but in 2012 I don't recommend going that way.)

TheLink (130905) | more than 2 years ago | (#40143261)

Yeah every now and then Slashdot has these silly articles about PC power consumption, "kill a watt" etc.

The power consumption of modern PCs (post P4) has gone down to a level where most home users would usually be better off looking for savings in other areas. Driving more efficiently, not using as much cooling/heating (and making it more efficient - insulation, sealing etc).

As for gaming, sure a high powered gaming rig will use a few hundred watts (and usually less if you're not doing SLI). But that's far from the most energy hungry way of having fun. Your hobby could be drag racing, or hiking/rock climbing somewhere that requires a 1 hour drive, or even baking cakes. FWIW even cycling and other sports might be more energy hungry if you replace the calories burnt by eating more of stuff that requires a fair bit of energy to produce ( e.g. US corn fed beef).

From various sources:
1 pound of beef = 13-15 pounds of CO2 ( http://www.usatoday.com/news/nation/environment/2009-04-21-carbon-diet_N.htm [usatoday.com] )
1 kWh = 2.3 pounds of CO2 ( http://cdiac.ornl.gov/pns/faq.html [ornl.gov] )
so 1 pound of beef = 5.6-6.5kWh

So if all that exercise makes you eat an additional half pound of beef (400kcal), that's about the equivalent of running a 300W gaming rig + monitor for 9 to 10 hours.

In contrast 1 pound of chicken = 1.1 pounds of CO2.

I've even seen many people here who say they still prefer to use incandescent lighting. It doesn't take that many bulbs to use as much as a gaming rig, even fewer for a facebook/browsing PC/notebook. A single fluorescent tube lamp uses about 40W already.

As a ballpark, for most regions I find calculating the yearly cost of an item on 24/7 to be about $1/watt.
13 watt cfl on 24/7, $13/year($4.33 for 8 hrs/day, etc), my Emachines e725 laptop, 24/watts so $24/year(less when screen is off,but it is 'on' 24/7). etc.

Great tip when buying large TV's etc you can quickly figure if that plasma is worth buying or not(for me, not).
And of course everyone should buy a $15-25 Kill-A-Watt or equiv. to see what appliances might be leaking etc(We found a fridge so wasteful a new one was paid for with the power savings in 3-4 years).

Rephrased, at 8.76 cents per kilowatt hour, one watt year costs about a buck per year. Plus or minus leap years and leap seconds. After endless add on taxes, and fees, and fees disguised as taxes, and taxes disguised as fees, that's probably about what I'm paying when I write a check.

Re:Power (2)

Re:Power (0)

Anonymous Coward | more than 2 years ago | (#40143279)

A rule of thumb that's very close for people paying a bit more for power is that each 10 Watts used 24 hours a day costs $1 per month. (divide by three for eight hours, etc).

It certainly makes it obvious that keeping an old faster-clocked P4 machine around left on as a router, server, p2p box, or general use machine, isn't so cheap after all.

Are modern machines as good at throttling back consumption by the the GPU as the CPU when peak performance isn't needed? Considering that even tablets can decode h.264 fine with optimized low-power hardware, most of us should probably avoid powerful GPUs if they aren't good at throttling down consumption. Having extra GPU power "just in case" might be a costly choice. What's in the better laptops that manage long battery runtime?

Perhaps someone can post some detailed data on GPU power use?

Re:Power (3, Insightful)

TWX (665546) | more than 2 years ago | (#40142133)

I have a meter as well; one thing to consider with replacement appliances is the reliability and longevity of the appliance.

I have a 33 year old Sub Zero built-in refrigerator in my new house. It's so old that it has only one knob for temperature adjustment, and the refrigerator compartment on top is slave to the freezer setting. I've removed the cover to the compressor and coils to clean them, and I've found some indication that a service or two have been performed over the years, but compared to a friend's brand new LG unit that's had to be serviced twice in eight months and had cost them $1600 to purchase, I'm happy to use this fridge for the moment. Plus, a new built-in refrigerator will cost between $4000 and $8000 depending on what brand and features are chosen. This unit can run for a very, very long time for $4000 worth of electricity.

As for TVs, one doesn't necessarily have to use the fancy, big TV all of the time either. For many years I had a projector screen that could roll down in front of the entertainment center, blocking the 27" TV in it, so I could use my projector when I wanted to watch something of substance. Now, I have the projector in a different room from the TV we watch the news on, and we only use it when we actually want to watch a movie or some other thing where surround sound and a big image matter. Obviously the roll-down method won't work with a fixed TV, but putting the fancy home theatre TV into a different room would.

My current PC (an old Dual-Xeon box) has a hardware sleep switch that ties into some pins on the motherboard, and when pressed the computer drops down to a low power state. When I'm done using it I just put it to sleep, and when I want to use it again it comes back in about three seconds. Works well, keeps all of my programs running fine, and saves power.

There are lots of techniques that can be used to save power, but the biggest hogs in the house (HVAC, hot water heater, refrigerator, oven/range/cooktop) don't hold a candle to the consumer devices that everyone always panics about. If you want the most bang for your buck, insulate your house. Change your windows. Plant some trees that increase shade on the structure. Turn your thermostat up a couple of degrees and install some high efficiency ceiling fans to keep the air moving a little. Sure, turn off the electronics you're not using, but don't assume that it'll be earth-shattering on your power bills just by doing that.

SJHillman (1966756) | more than 2 years ago | (#40141981)

What about switching out power hungry gaming cards for newer, more efficient cards? This year's mid-end model may have comparable performance to last year's mid-high end model but might draw half the power. Over time, the lower power consumption adds up, not to mention you can get by with a smaller power supply. Likewise, trading in your hard drives for a solid state drive (maybe using a green HDD for extra storage)? And for old timers, switching out CRTs for LCDs? Overall, I think it'd be easier for people to upgrade to more energy efficient components than it would be for them to change their PC usage habits. Lowering the sleep/HDD shutoff/monitor shutoff timers can make a big difference too without having to remember to shut down your PC every day or waiting for it to reboot. Not an option for everyone, but gamers usually aren't on a shoe-string budget or else they wouldn't be able to afford the PC and the games in the first place.

xdroop (4039) | more than 2 years ago | (#40142315)

This doesn't work for the same reason that virtualization rarely yields absolute savings. Instead of "doing the same with less", the pointy heads see all this newly-freed up hardware and decide to re-use it. You end up "doing even more with the same". So your costs-per-work-unit go down, but your absolute costs stay the same (or go up once virtualization costs are factored in).

The same goes for people buying hardware. We rarely say "oh, I can buy this computer that has A) the same performance and B) better energy consuption rates as my existing one for less than I paid for it" -- we say "oh, I can buy one that is so much faster and powerful (and ususally, energy-hungry) than my existing one for the same as I paid for the originial".

Why spend more money to get what you already have, when you can spend more money to get -- more?

laffer1 (701823) | more than 2 years ago | (#40143387)

It really depends on the situation. For example, I build packages for my open source project. The computer science department donated 20 machines for use in a cluster while I was there. I could build around 2000 packages in 10 days. After I left the university, I had to do it with my own computing equipment. Today, I can build the same software in about 2 days with my desktop computer. If I were paying for electricity use to run 20 Dell optiplex systems with pentium 4 1.7Ghz-2.0Ghz + IDE disks to the Phenom II X6 1090t with raid 0 IDE + 2 SATA disks I use now, I'd save a lot of money with the new build.

Most people don't do what I do, but I think it does simulate a CPU and disk intensive work load one might see in some business settings. There are times that virutalization can save money on electricity. Of course, the cost for the disk subsystem to pull it off may far outweigh the savings. In my case, it wasn't that bad and I don't use virutalization for the setup. The software is setup to run multiple jobs in parallel.

Back when I ran builds for SPARC, the two sun machines I had used about $30 in power including air conditioning.

I don't think buying new gaming hardware is going to save anything because video cards seem to use more power now. I just bought a 750 watt power supply because I finally upgraded my aging video card and between that, 6 hard drives and my Phenom II, the system was blue screening during gaming. I've also got a mac pro that uses about 300 watts when idle not counting the display. Conversely, my laptop uses about 32 watts (AMD A6 quad core 1.4Ghz) There's a massive difference between what consumers buy and what some of us run.

L4t3r4lu5 (1216702) | more than 2 years ago | (#40142365)

I don't think the parent is suggesting that you buy components to replace fully functioning and useful parts just to save electricity. Potentially, though, you could save real, actual money buy buying newer parts than upgrading your current, old hardware.

I ran an 8800GTX until it died, but it was around 6 months ago and I decided I needed an upgrade (before it failed). If I had gone ahead with the upgrade, I would have paid £100 for the card, and another for a 1kW PSU to handle the draw. Those cards pull north of 320W under load! Thankfully (?) it failed before I upgraded, so I went with an AMD HD6950 instead, and haven't looked back. Performance improvement is wonderful, power draw is down 50%, and I didn't need to upgrade the PSU (meaning the £200 budget could go on the card).

However, having just also upgraded the bare-bones too, I can safely say that the biggest power saving you'll make is upgrading to an SSD. Power draw isn't the issue; It's the fact that you can go from power-down (hibernate or cold start) to working in ~20 seconds. It makes sleep and low-power (but still working) states pointless, so you'll power-off almost every time you leave the thing for any period of time. Again, only if you're looking to upgrade, but worth considering.

I should have stipulated that the graphics card upgrade was going to be a second 8800GTX in SLI, meaning graphics alone would have drawn around 650W.

Yes, I was referring to regular upgrades you might do anyway. For example, the Radeon HD 7850 (this year's mid-end model) and the 6950 (last year's mid-high end model) have comparable performance, but the 7850 draws about 2/3rds the power or less depending on benchmarks. The 6950 sells for less, but the power consumption may make the total cost of ownership similar to or greater than the 7850.

Even with a lousy HDD-of-no-particular-importance, I find that the big timesuck on boot isn't the booting; but the "getting all the browser pages and documents and whatnot back to where I left them(yes, even in applications that support session restore, you still run into issues like webpages that have decided to nuke the contents of form fields and such)" problem.

For that reason alone, the only real choice is between suspend-to-RAM and suspend-to-disk. With your contemporary soft-off PSU burning a few watts so that it can detect you waking it up, the difference between 'off' and 'suspend to RAM' is the relatively low, unless you have absolute piles of the stuff, cost of keeping your RAM refreshed.

Waiting for it to reboot? I'm still running spinning disk on a Phenom II X4 system and it takes maybe two minutes at most to get to the desktop and finish login processes (Kaspersky is a different story). Turn it on and take a poop or something. Watching that Windows flag just makes you perceive it taking longer. Now, I'll go ahead and leave my work laptop with full disk encryption out of this. *That* is painful.

He's comparing apples and oranges.

Let X be the cost of normal, non-gaming usage
X + $30.83 = cost of gaming 20 hours a week in addition to (or in place of?) normal usage
X - $66.66 = cost of non-gaming usage if you shut down the PC when not using it

But what is his time worth? If I value myself at the same rate my employer values me, then the startup time of my computer costs about 15 cents. I use the PC in the morning before work and in the evening after work and throughout the day on weekends, so that's 30 cents a weekday plus 15 cents for each weekend day or $1.80/wk. 52 weeks in a year, so it costs about $93 of my time waiting for it to boot up. If you have downtime in which you'd be doing nothing otherwise, then it may be worth it. If your schedule is usually tight, then it's cheaper to leave it on all the time.

Turning off something saves money? Really? (2)

Liquidretro (1590189) | more than 2 years ago | (#40141999)

Wow, earth shattering news here, turning off your PC when your not using it saves you a significant amount of money! What about factoring in cooling costs. High end gaming machines put out a lot of heat too. Since many gamers are using SSD's these days, sleeping your computer is great, they resume so fast. It's just common sense. I make sure everyone in my house shuts down or sleeps their machines at night if there is not a valid reason why they are on. It really does help. The real problem with this list is where is the spec list? That dual or triple GPU machine, that is water cool, and has a huge overclock will use a ton more power then your i5, single GPU machine. Finding an average gaming machine is tough to do.

Everything on my computer from Outlook to Chrome to Office shits itself when I resume from either sleep or hibernation. Mapped network drives give me popups saying the server is unavailable (on top of the explorer window where I'm browsing said "unavailable" server). Outlook either tells me my inbox is unavailable or sits stuck about halfway through send&receive until I close it or it eventually errors out and then I have to close it anyway to get it to reconnect. I once made the mistake of leaving photoshop open and minimized overnight, in addition to having to wake up from sleep I had to wait about 5 minutes for photoshop to finish unswapping and redrawing all of its tool palettes before I could close it. Chrome sometimes comes out ok and sometimes does this thing where when I type in a URL, the tab's icon spins and spins, but there's nothing happening (the status bar doesn't even say Looking for... or Waiting for... and the mouse doesn't show the spinner either)

And people whine about the state of Linux's power saving? If I've got to close all my programs before I let the computer go to sleep, I might as well choose shut down (and I do.)

Sentrion (964745) | more than 2 years ago | (#40142593)

I have always seen these types of problems with the so-called "hibernate" or "sleep" modes. I always disable this feature the first chance I get. The ridiculous amount of time required for the rebooting process hasn't improved much since Windows 3.1. The more software you use on a daily basis the worse your problem gets. Let's say to like to keep track of your schedule with a PC based organizer. If during any particular weekend day you only need to update your schedule four different times and random intervals throughout the day, you are not going to be using you time efficiently if you wait 5, 10 or 15 minutes to boot up, log in, open your software, etc., especially if the task you want to perform only takes 30 seconds. So, most people who like to use their PC software throughout the day but for short intervals at a time, it almost becomes impractical unless you keep your machine on all day long. Now, of course, you could always turn off your machine and spend 3-4 hours each day doing things that don't involve your PC, but if you need to quickly look up something that you have recorded on your hard drive or somebody calls you and needs you to do something quickly for them, then keeping your machine on all day, even if mostly unused, is an unfortunate fact of life. Mobile apps might help to liberate you from your machine, but that depends a lot on your particular situation. Saving $60 each year might be worth it for some people, but not for everybody.

Of course the benefits are, water savings because of less baths, no social costs (coffee shops, movies, dates, video rentals, vacations, etc), not expensive presents for friends, less electricity used in the house because no other lights are used, furniture reduction, lower vehicle maintenance costs, lower automotive fuel costs, and more leet gear

I would suspect C3 sleep states are supported on a majority of systems by now. Perhaps I was just lucky when I picked up the hackintosh board a few years ago. Now, I simply use a reasonably long idle timer and the system goes to sleep/power off. It takes a few seconds to come back out of that state and wholly beats a cold start.

I guestimate my home system gets about 3-4 hours of usage each day during the weekday. In addition, there are plenty of other device around the house which support other core services.

I don't know if it's so much about being green as it is the sensibility to turn a light switch off if it's not in use.

Lame (0, Flamebait)

vlm (69642) | more than 2 years ago | (#40142049)

Lame as heck.

Does he game in a pitch black room? My basement (my basement, not my moms basement) used to be lit by 800 watts of incandescent lights on tracks (which isn't all that bright for 30 x 30 feet), and as they burned out (which took awhile) I replaced then with $50 LEDs that will pay for themselves in saved ecological and energy costs in a mere five million years of operation. Anyway the point is my lighting electrical budget in the basement was an order of magnitude greater than my video card power budget and the capital costs are darn near as bad. Depreciation schedule is much longer however.

Another issue is my property tax is very roughly $2 per square foot of my house, and my desk (which is admittedly pretty luxuriously large) is about 20 sq ft and my elaborate "executive reclining office chair" is probably at least 4 sq ft extra, lets call that 25 sq ft * $2/sq so you're looking at $50/yr rent to the city (aka prop tax) simply to store the machinery, which is about twice the supposed electrical consumption. Now if you want to see high annual average specific power consumption per sq foot, try the 4 sq feet where my clothes dryer resides... Or my furnace, or air conditioner compressor...

Another way to look at it, is I splurged and dumped $200 of environmental and energy degradation into purchasing my last video card a couple years back. The electrical cost will approach the capital cost of the card, assuming the video card is the only consumer of energy (LOL) at $30/yr, in 2017. Of course the card will be functionally obsolete before 2017.

So if you can afford a gaming rig and can afford to upgrade it every five years or so, you can simply ignore the costs of operating it as a rounding error. Or the operational costs only matter if you stole the gear or got it as a gift.

Kind of like, if you can afford to buy a $60K SUV or pickup truck, then $4/gallon gasoline is merely a rounding error to be ignored. Or if you buy a $2M california mcmansion, a $1K month air conditioning bill is a rounding error compared to the mortgage (to say nothing of the decline in property values)

Re:Lame (3, Interesting)

Simon Brooke (45012) | more than 2 years ago | (#40142333)

My home has on average 100 watts of power available. I can use more in the short term, but doing so depletes the battery and means I'll have to use much less for some part of the week. The wind turbine which is my sole source of power is rated at 750 watts, but only generates that much in absolutely perfect conditions. So I know quite a bit about how to use power economically. I can light my whole house effectively with just 18 watts of LEDs. They're strategically placed, yes - but you can easily read more or less everywhere.

In this situation, the graphics card on my computer (Radeon HD 6850 at 127 watts TDP) is actually the biggest power drain I've got. Obviously, my gaming is limited to two or three hours a day... Power is worth thinking about.

While I'm not against conservation, and indeed I do turn my PC off when I'm not home because why use what isn't needed, you can't try and use your situation to apply to the population at large. 100 watts is NOT something I have to think about. My house has about 15,000 watts of power available to it at all times. 100 watts more or less is not noticeable and is well within the margin of error I get depending on how the AC is run.

All in all, that is really peanuts in terms of electicity bills. If you are spending roughly 2 hours a day gaming, a normal person with a full-time job and a family would have very little time to do much else that can sink money.

Considering that yearly electricty bills routinely reach about a $1000+ for a standard household [eia.gov] , this added 10% due to gaming is pretty insignificant when compared to other hobbies...like racing cars for example.

Sure, there may be cheaper hobbies, but I honestly don't think anyone well-settled enough to be practising a daily hobby and deriving enjoyment from it finds it a problem to spend 8 bucks 50 cents a month for their recreation.

I'm not sure what exactly the article is trying to convey here, as measuring electrical consumption is merely fine-tuning an existing expense related to a hobby, and an obscenely small amount of money being measured at that (c'mon, ~$30/year? People who will spend twice that much in a month on caffeine just to play said hobby).

Compare playing video games to spending money on cable TV. Or going to the movies. Or riding a bike outside. Discussing literally pennies of electrical savings per day seems rather pointless when you're spending considerably more to sustain that kind of hobby in the first place.

why do all such examples use the cheapest rates? (1)

0111 1110 (518466) | more than 2 years ago | (#40142413)

As of my last month's bill I am paying 28.8 cents per kWh. I'm not sure how much power my computer uses, but with my Nvidia GTX280 and an overclocked 4 Ghz dual core CPU I would assume at least 400 watts. Particularly while playing a game. So let's say 12 hours for a day of gaming. So 4.8 kWh or $1.38 per day of marathon gaming. If you assume 4 days per week that would be $22.12 per month or $265.42. Of course my computer may actually use 500 or 600 watts while gaming. What interests me more is how much power my computer uses when I'm not gaming. There have been times when I've just left my computer on all the time. I would suspend to RAM, but I usually run Windows and I have yet to find a version of Windows that will properly wake up from an STR properly. That's why I'm thinking of switching to Linux. Suspend to RAM works perfectly for me in Linux.

So maybe instead of blabbing crap about you do something about it?

1. get a kill-a-watt meter - it's $20 in ebay
2. plug it in and see

Guessing how much power you use is stupid without actual measurement.

Secondly, this is not the "cheapest rates". These are typical rates in the US. Where I live, I pay 6.5c/kWh, which is one of the cheapest rates.

1W power usage => 8.76kWh/year utilization.

So for me, each W reduction, it saves me about $0.60. 100W = $60.

For you, 1 W reduction in usage (eg. standby) yields $2.52. So maybe your usage of suspend to RAM is not a good thing - it costs you $10-$20/yr.

Anyway. Spread the cost of time across the year while waiting to boot. This could easily be higher than $66 for those of us making a reasonable wage. As an object exercise, 30 seconds per day for 365 days is about 3 hours. If you make $22/hr then the savings is a wash. Just a simple example.

what is the true total cost? (0)

Anonymous Coward | more than 2 years ago | (#40142671)

this is only the immediate direct cost. the true total cost is higher. this is because there is an environmental cost that is not accounted for in the generation of electricity. we don't live in a static universe, so if we don't take the hidden costs into account the full repercussions of our choices will not be apparent.

also, assessing the cost simply in monetary terms has a feedback effect that keeps us unconscious of the actual impacts of our decisions. we stay focused on things like saving more money, or making more money, etc. what i'd love to see is a holistic analysis in terms of money and something like (say you were using hydro-power) the number of salmon that the dam prevented from spawning each year for a year of gaming. which would provide a less abstracted context for decision making.

as someone who cares about the state of the world, imho, maintaining a holistic perspective on *everything* is a requirement for being a good steward (a responsibility we are all born with whether we take it up or not). whenever i fail to looks at things holistic i have failed as a steward. this is because we are all (humans, rocks, air, animals, etc.) interdependent.

You're working on one of the smallest possible incremental changes in your house's electrical usage. What's the point?

The wall warts (AC adapters) scattered about your house almost certainly use and waste more electricity than your PC. The US EPA guesstimated in 2005 that around 200 gigawatts (6% of US total power) goes through these things, and a significant portion of that (30 - 50%) is wasted.

See http://www.buildinggreen.com/auth/article.cfm/2005/3/1/Efficiency-Standards-for-AC-Adapters/ [buildinggreen.com] Getting all your wall warts onto centrally controlled power strips would seem like an interesting and money-saving challenge. If anyone has done that, I'd love to hear about it.

If he weren't interested in gaming he could likely make do with a much less powerful GPU and/or possibly a more power-efficient CPU. The combination of those two would reduce his power consumption even further during non-gaming-related computer usage (or idling).

HangingChad (677530) | more than 2 years ago | (#40143827)

To really figure the electrical cost of gaming, you have to figure out what else people would be doing if they weren't playing games. Some activities, like watching TV, would use as much or more power.

My guess is if we calculated the energy use of those other activities, gaming might be a net energy saving activity.
