The Times had this article:

The most intersting fact I noticed was that he power wasted by phone chargers plugged in in Britain each year could power 66,000 homes. It doesn't mention cordless phones, though other sites suggest they fall into the energy wasting catagory too.
Clearly each household's contribution to this is small. But it's the combined effort that counts.
The BBC mentions that an average PC on standby consumes about 10-15 Watts. A few similar appliances and you have a 60W bulb's power being used unecessarily.

I tend to agree with Everhelpful, but maybe for different reasons.
People who never stop nagging tend to say "what if everybody did it/stopped doing it". Point taken, but in this case my action/inaction won't persuade anybody else to change.
So what I do has no significance whatsoever. The only consideration is the cost to me and whether I think it worthwhile.
If stand-by buttons are to be made illegal, that's an entirely different kettle of fish!

I'm not sure that whether your action/inaction brings about a change in others is the point of the "what if everybody did that" argument.
I give a set amount to charity each month. I know that whether I do or not will not affect the giving of others at all. I also know that the charity to which i donate receives millions of pounds each year, so my contribution is minuscule in comparison. Does this mean that my giving to charity has absolutely no significance whatsoever? I'm not convinced.
It's not about whether you can effect others, or whether your contribution makes a noticable difference. It's about changing anyway and hoping others do the same. At least for me it is.

There is another side to this debate. First in Winter. On standby, the devices radiate the power as heat. Assuming that you have some form of thermostatically controlled heating, then leaving things on standby just reduces your actual heating consumption
Different story in summer though as, if you have aircon, it will work harder.
