At the present time my desktop PC uses about 1 kilowatt hour of electricity, per hour costing about 7.7p per hour.

The computer is usually in use 14 hours a day & 365 days a week.

Does any one know approximately how much electricity I would use if I was using a laptop ? I assume there would be a saving.

rubbish. unless you have triple crossfires 5970's and an Intel Presscook, you won't be using anywhere NEAR 1kW
 
when my PC & screen are on it uses about 1.6p of leccy, that means between 150-200w.

How do you know how much you computer is using? using your numbers you are spending nearly £1.08 a day and so around £393 a year just for the computer. I somehow doubt that.
 
Most laptops don't use more than 125w and for that we're talking models with Core i7s. You would probably save money switching to a laptop but would a laptop be able to take the stress of what you do on there and it being on for so long.

and by the time you factor in the price of switching, it would take 20 years to pay it off with teh savings from ellecy.

As Said you will not be using 1kw that is just the maximum your PSU can deliver.

You can also customise power saving options to suite your needs and uses.
 
My Dell D600 laptop uses around 60w,

My work pc uses around 170w, this is an e2120, 4gb ram, 3 hard drives and 2x 19" screens

Hair dryer was around 850w iirc! I should bring my plug thing back from work to test a few things :)


Not sure what my gaming pc uses, but it's always in S3 sleep mode, unless I'm playing a game. I just use the laptop for browsing the net etc
 
Macbook pro I believe uses 85watts

Your computer won't be using 1kw

And I feel a bit bad, I have 3 computers running 24/265
Although I don't pay for the electric!

You sir are rather efficient. That's what I would like to transition to, rather than read my ebooks on my main pc, view them on a notebook or less.

I also turn my pc off at the wall over night (and any other extras that don't really need to be on). Makes a nice little saving, shaving off a few pounds on my bill.

And before any one jumps me :P I'm not telling you how to live your life, just how I live mine.

To OP, laptops are expensive when you try to replace your desktop with one. Consider what your going to need it for, and then set your budget. There isn't a point in buying it if your only going to spend 10% of time using it. Also by no means does a laptop work out more efficient than a pc as Intel's motto shows, go faster to get work done quicker :D (which doesn't work with laptops since that would mean eat battery so you have less time to use it before recharge).
 
I dont bother turning stuff off at the wall, but i do turn the TV off at its button rather than standby and my PC is always off when not in use for something.

My 3 bed semi with 2 people costs 1.8p an hour to run when we are asleep. My monthly electric bill is about £20 (electric shower, electric oven, gas hob/water/heating)

Using a Meter, we use 30-40 a week. Between just 2 of us. TV is on almost 24/7 but that's it, everything else goes off. Any ideas? :D
 
My machine idles at 165w and loads at 320w, so loading my machine for 3 solid hours costs me around 14p, and the same cost would see me idle for 6 hours.

I'd say the machine is on for 70 hours a week, so splitting that 45 hours idle and 25 hours load would be about 16kwh, £2.20 a week, or £9.50 a month.
