Do you think this is an accurate figure?

Hi,

Firstly, I hope this is in the right place. If not Modsd can you please move it for me and accept my apologies.

I found this whilst having a bit of a look around. It seems like an awful lot per PC to me. What do you people think?


UK companies lost £90 million this year by failing to turn off their computers.

Computer experts 1E says businesses could save up to £100(Approx $150) per PC in unnecessary electricity costs each year just by switching PCs off at night.

But few firms bother with the potential savings and 63% of computers are left on at night.

The consultancy says the result is also an extra 2.8 million tons of harmful CO2 gas being pumped into the atmosphere.1E, whose clients include Tesco, BA and Microsoft, used research from the University of California and UK government studies.

Government statistics show that 50% of office energy is consumed by PCs and half that energy is wasted, says 1E.

Wasted energy is not only bad for profits, but also bad for the environment, according to the figures from California.

A PC switched on for 24 hours a day will emit up to one ton of the greenhouse gas CO2 a year, contributing significantly to global warming.

In addition to the 2.8 million tons of CO2 gas pumped into the environment in 2002, 1E said the pollution is set to rise to 3.7 million tons by 2020.

Where's the source article from?

The story has no credibility if there is no source.

I shouldn't jump on this...but I will. I am highly doubtful of your stats as far as greenhouse emissions from a PC. I have done my studies, and the findings on global warming are, in general, deceptive. Where did you get your sources from? A scientist - or a journalist?

For comparison - how much more CO2 is a PC going to output (no burning of fossil fuels here) than a person breathing?

[Theophylact]

I haven't run the numbers, but "greenhouse emissions" by a pc is going to mean primarily from the fossil fuel used to provide the electrical energy to run the thing (plus any produced in incinerating dumped ones, I suppose).

i say blah. bunch of poppy ****. i leave my three computers on all the time. 24/7 except for reboots of course. servers have to stay on 24/7 so thats a nada. thing is, all the companies I know of in the U.S. (medium sized ones anyway) turn all workstations off at 5. servers stay on for months at a time and are only rebooted for patches and security updates. i think alot of the global warming stuff is non-sense. i think we need to be careful with what our Creator has given us, but lets not go to the extreme.

many computers consume less energy than their older couterparts ie: 486/pentium machines, windows has numerious power saving functions, newer intel processors have power saving abilities, more and more machines have TFT monitors which use much less power than their crt brothers.

my yearly power for my 2 computers being left on 24/7 is around £50 a year, i switch my monitors off when not in use, also any devices such as printers.

with reference to tesco, i work for a similar company and the work stations here have all been replaced with newer ones that go into a deep sleep after 10 minutes of non-use.
in the uk councils are now implimenting recycling procdures for computers and charging people if they don't recycle them.
personally i dont throw any computer stuff away i recycle used cd-r and cd's and give or sell other stuff.
i have a paper bin that all paper from is re-cycled.

i do this because when i have children, i want them to enjoy this world like i have.

[capybara]

well if u turn the computer off, you will save electricity, BUT....
the computer will fail sooner and require more tech support.
imho, to keep computers running the longest, dont shut
them off.

[thronka]

hehe.. global warming.. whatever.. its a bunch of pure crap from these government agencies trying to control us.
Althought if you are gonna be gone for about a month then turn your PC off to save the money because you aren't gonna use it. Thats what I do when I go on long vacations during the summer and thanksgiving.

I recycle my paper and old CDRs with old backups to save plastic and paper. I need them for :::crawls:: music! Save the planet for my music!

Just looking at the $ saved from turning the PC off, not the greenhouse gases.

Computer experts 1E says businesses could save up to £100(Approx $150) per PC in unnecessary electricity costs each year just by switching PCs off at night.

While this figure might be true, how much would it cost the company if the machines were not being used during working hours because of updates and such. The company I worked for left the PC's running 24/7 because we pushed updates and patches during non business hours. If we were to push them during business hours we would have lost $150 per person per update.

I am sure that this source has some validity in the Electrical cost section, but i wouldn't believe the CO2 thing even if the plants thrived around my computer. Nobody has the time to waste to make up figures that sound within reason and post them up on the net to screw with people. I find it funny that someone would post up how many Tons of CO2 was released, and causes global warming.

Did anyone in here forget that this world and everything that operates here, operates in balance? Soo if you get more CO2 in the atmosphere, plants will begin to grow faster as there is more material to synthesize with water and sugar, and this results in more CO2 being absorbed, faster. And more plant life means more moisture to be evaporated, which means clouds, and clouds means cooler air, and clouds=rain, and rain=cooler air, and then the sun evaporates this water and evaporation=cooling. crap, id be more worried about global cooling than global warming. Not only that, but if any of you remember Science 101, the atmosphere is <70% Nitrogen, 2% CO2, 10% O2 (is that right?) and the rest is fluff. So techincally we should be dying nitrogen deaths rather than a massive 2 percent co2 death.

*breathes*

but we could also look at the other end of the power spectrum. What percentage of your power is nuclear/coal/oil/hydro? In my area we are 20%/65%/0%/15%; so this means that in order to power my computer, i might as well be using coal to burn. thank God we are using "clean" coal these days. and then a touch of Uranium 235 in my PSU too. so if we turned off our computers at night, we would be directly contributing to global pollution, rather, that power that isn't used is wasted, so would you rather waste or use?

That decision is up to you.
