Lots of appliances use a very small amount of energy to keep memory or display a clock. I would have to say that the saving would be soooo minimal. Try unplugging everything in the house... turning off the lights.. etc (even the fridge) go check your electrical meter... make sure the wheel is not turning. Now plug in, say, the stove... set the clock. Now go look at the wheel again. It will be moving so slow because its really not using much at all.
I would take a bet that over the course of a year, you would save $5.
Someone with more electrical experience needs to post an answer.. this is just my guess.
There are many variables to answer your question there are some items I would not unplug but many I would. Anything that has standby power, a clock uses energy if it is plugged in. I have a meter called a KILL-A-WATT and what it does is you plug it into the outlet and then you plug an item into it, it will tell you what amount of energy is being used by the item so you can see a clock on a microwave is much like some answers have said and is minimal (2-4 watts)but also that some tv's, computers, dvds, vcrs use as high as 60 watts. With that being the case let me tell you about an example and you see if you are close to them I will even say that my example the family of four buys all energy efficient items and have no big phantom load items. We will say each item they have puts out a meager 5 watts
The family has 4 cell phones with 4 chargers =20W
Two cordless home phones and the associated answering machine/chargers =10W
Two TVs =10W
a gaming station (wii,xbox,play station, whatever)=5w
2 computers =10W
with a printer and either a router or at least one usb device=10W
Charging stations for power tools or rechargeable batteries, dustbuster misc =10W
Beard trimmer that sits by the electric toothbrush=5W
3 alarm clocks, a clock on the microwave= 20W
I'll stop here but when you think about this is not only realistic but in some households a very incomplete list, and it is a very low energy profile as you can tell for yourself buy a Kill-a-watt meter plug it in check out those dvds and vcrs some use almost as much energy off as they do on. In my example they are the equivalent of leaving on a 110w light forever, you pay for electricity by the kilowatt/hour in one day the example family wasted 2.64 kw at an inexpensive rate of a dime a kw that is only 26.4cents x 365 days in a year= $96.36 so if you get cheap electricity and you have less items than the example family and if all none of your phantom loads are 5W and not as high as the 60w I have seen you only wasted around $100 dollars. Not to mention if everyone does this now we need to build a new power plant better figure taxpayer money to build that in there.
HERE'S THE EASY ANSWER:
Don't work yourself into a frenzy plugging in and unplugging all your appliances, get a power strip I have one for the kids room they have a TV, dvd, wii gaming system, and a phone charger plugged into it when they aren't using it they flip one switch on the power strip and then none of those items wastes energy. I do the same with most of my electronics with a flip of three switches I save over $100 a year painlessly and feel good about showing my kids we are attempting to waste less.
I unplug everything that I can that might possibly be using any energy and also shut off lights immediately that aren't being used for anything. If something operates off a small battery in order to operate a clock or small display, then I don't worry about it.
If it's using electricity, and that electricity is something that I need to pay for, then when it's not in use and not needed for anything, then it's off and/or unplugged.
I also agree that Capuchin doesn't deserve a "disagree".
Maybe I should have said 4 Watts per device with a phantom load.
The problem with unplugging things like a VCR, for instance, is that it looses the time. Some systems loose all their information. Some use a supercap to retain their information over a short amount of time. Still other's use a small lithium battery that may be difficult to replace. Computers fall into that category.
My math was bad for estimating. I caught it and corrected it. We all make mistakes sometimes.
The answer to that is no, if the on/off switch is a real on/off switch.
The answer is yes, if the on/off switch is a stand-by switch.
Another energy saving can be obtained by unplugging unused transformers, like chargers for telephones.
There is an increasing amount of equipment that has no real on/off switch (radio-tv-dvd-vcr-display units-etc.) Also many computers are never switched off.
Another feature that draws current continuously is a bell transformer, drawing a small amount of energy. A battery powered bell would be energy saving!
All these units use small amounts of energy in the stand-by mode, but together the amount adds up, specially as most are drawing energy 24 hours/day.
So yes, unplugging or real switching off unused equipment is saving energy.
If we all would do that, it would be a considerable saving on the national energy bill.
There is even some pressure on the electronic industry to reduce all these stand-by modesm and at least install a real on/off switch.
I think we all need to think more critically about constantly unplugging some electronics like TV's or DVD players. The vampire power is there for a reason, to maintain heat in the CPU's or circuit boards in the electronics. All the extra thermal cycling i.e.. Heating and cooling of going from cold circuit board to hot by unplugging will cause premature failure. So you might save a few dollars per year, but then have to replace the electronic device much sooner. Which one is really saving you money, and the environment ? Save $5 per year in electricity or buy a $500 electronic device a year sooner ?
The other day I looked at my electric meter and the dial was whirling around like a merry go round. I was surprised since I was the only person home and no major appliances were running. I went around the house switching off power strips with computer equipment and monitors plugged in (all NOT In use) and then ran out to look at the meter. It slowed down noticeably with each strip (one per teenager and one for the xbox and stereo). My electric bill has been high lately. I just opened the electric bill... and it is $40 less this month.
$40 X 12 is $480, my maths.
Will the computers really all fail prematurely if they are turned off? I have never heard this and would like to see a reference if you happen to have one.
Hello, can anyone help? We were painting our house and my wife washed the pan and the brushes in the bathtub. Now the bath tub is plugged... we have tried with Drano-gel(twice) and still doesn't work. The water is going down but it takes about an hour :-( not sure what else to do as the paint might...
