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.
