How much power does it save..
« on: 18/10/2007 23:58:38 »
1.) I'm surprised I haven't posted here yet, with me knowing a little more then most poeple my age about computers and technology.

and 2 my question.

2.) Dad was complaining how high the power bills have been..And I've been leaving the laptop plugged in 24/7. Now I have it set to stand by after 2 minutes and then turn off all the drives after 3 mintues after I leave for a few hours or go to bed, but when I'm on it I just have to set to turn the monitor off after a while.

How much power does it save?

Only the equivalent of a light bulb but
1.Do your really need it on when you're not there?
2. How long does it take to power up when you need it?
3.If everyone switched everything off, when they were not using it, that would represent a serious amount of energy saved.
4.Who pays the bill in your house? (Very unfair question - I'm sorry!)

I take it that your computer is either elderly or has a lot of stuff, clogging it up if it takes 10minutes to wake up.
Tell your Dad that you'll switch it off if he'll buy you a zippy  big new one!

There is nothing slowing it down..I have ran DeFrag, all the bells and whistels and it still takes for freaking ever to start up.

For a laptop, with drives and screen powering down, I doubt it should even take as much as a light bulb (a desktop, while idle, could use about that much - although I suppose one has to ask what size light bulb).

How much power does a 70 watt lightbulb take if its running 24 hours a day for a month?

0.07X24X30=50kWh per month.
Say 5p per unit - costs 2.50
But, you're probably talking more like 10W of standby power - so  less than 50p ($1).
Hardly worth worrying about until you realise how many people X devices this applies to, in total.

I think you'll find electricity in the UK now costs more like 12 pence per kWh unit...  :o

So for the above example (70Watts 24/7) costs £6 per month.

(my latest bill is 13.55p for the first 210 units/qtr, 9.3p for the remainder, then you need to add 5% VAT on top of that)


If you're trying to get your electricity bill down, consider:
 fridge and freezer (around 200kWh/yr (£24/yr) for a big fridge, 500kWh/yr (£60/yr) for a big freezer)
    make sure the fridge doors shut properly, and the freezer isn't in desperate need of defrosting (both will increase the power consumption)
 Any kind of electric heating appliance - electric fires, and cookers use a lot of power
 Exterior floodlights typically 300-500W - will soon add up if used much.
 TV/video/stb on standby could easily add up to 30W or more, so 24/7 would cost £32/yr

There's a pattern - at today's prices, an appliance running 24/7 will cost its (average) Wattage in pounds, annually. i.e. An x-Watt appliance will cost £x per year.

I'm living in the past about electricity prices - I just didn't bother to look at my recent bill./
