Ok, a more serious and hopefully, helpful post now!
Major loss of heat in the home is draughts - front doors, windows etc. If you haven't got double glazing then get some thick curtains from your Freecycle friends

.
I ASSume your loft and immersion tank insulation is good?.A tank that loses lots of heat is eating up your electricity (making an assumption you have electric heating here of course).
Leaving appliances on standby - big no no.........TURN 'EM OFF! If you keep forgetting, it's worth investing in one of those thingies that turns everything off for you at night.
Heating water - just an hour in the morning, an hour in the afternoon / evening should suffice for washing up (OMG - you run a dishwasher right?? Hmmmm, then make sure it is FULL before you switch it on and don't be so lazy with that rinse-and-hold programme; rinse them by hand under the cold tap). Then just boost it if you want a bath rather than leave the immersion running all the time.
If your freezer is not full then stuff it full of newspapers and keep it well defrosted.
Electric cooker? With mine, I turn the rings off about 10 minutes before I want the meal ready; there's enough heat in the rings to keep on cookin'. In fact, I discovered something great the other week in a power cut. I had *just* bought some rice to the boil when the electricity went off (we get about 1 a week around here), I left the lid on the pan and within half an hour I had perfectly cooked rice - neat huhn?
Use a slow cooker and / or steamer - complete meals for a fraction of the electricity consumption and no, don't use your microwave - bad, bad, bad for your immune system (imnsho)
If you bake, do a weeks (nah, forget it, you don't bake do you??)
You really don't need to use the tumble drier AT ALL......
Only wash on a full load, despite what your expensive washing maching promises it does for you. (what me, a complete skeptic??!!

) and most washes only need to go in on 40degrees
There quite a difference between CRT consumption and LCD screens if that's applicable (huge benefits to your health too, but I won't go there)
Close warm cuddles and hot water bottles instead of that electric blanket........
Dimmer switches on your lights?
Great topic Fruity - you've got me thinking too, but this week I'm focusing on my rubbish!
