OK, have now dug out figures from my household (bearing in mind light bulbs used to be 100W, 60W and 40W, and are now approx 20W, 14W and 7W).
LCD flatscreen TV
standby: 12 W
on: 49 ? 65 W depending if I'd used energy-saving setting in menus
laptop
(sorry, no figure for "sleep" mode - but DP says vv low)
in use: 21 ? 59 W depending what it was doing - starting up and charging both heavy use
HP inkjet printer
on at wall but printer's little blue light off: 14W
printer's little blue light on, but not doing anything: 21 ? 24W
printer scanning or faxing: 24 ? 26W
bathroom extractor fan
in use: 16W
fridge
I'm can't find published figures but fridges/freezers are power-hungry. When we were investigating solar for some of my African family, having a fridge was going to double the number of solar panels needed.
So it took the same as old-fashioned lighting, small TV and computer put together.
The conclusion I came to is, if it's easy to switch off printer and TV, etc at wall, do so. But the savings are less than from switching from old to energy-saving bulbs, or from replacing an elderly fridge with an energy-efficient one (if you can afford it, of course).

DP has just added, newer printers are much more efficient, and you should be able to look up your model's power consumption (google "Epsom" and the model number, there should be a data sheet). If you have any probs, tell me the model number and DP will try.
