Saving electricity
If something requires 30 minutes cooking time in the oven, check on the item at 20 minutes, then turn the oven off, it usually takes longer than 10 minutes for the oven to cool down if the door is shut.
Then if you have any wet laundry hanging around, put your clothes drier in front of the open oven door afterwards instead of using the tumble drier.

Penny pinching indeed but in the long run, if you are on a very tight budget it does all add up.

Viz style tip on the same theme.
If you cant afford to heat your bedroom, put your mattress on the kitchen floor in front of the oven after you have cooked something ;)

good advice, but can backfire.
I used to live in a tiny flat. The main room had a kitchen counter along one end with a cooker in the middle, so on winter evenings I'd cook my dinner, turn off the oven, and leave the oven door open. Combined with the thick heavy floor-length curtains covering the room's single window, this would keep the rest of the room snug until I went to bed.

Until the evening when, a couple of hours after dinner I realised that I had an awful headache and was rather uncomfortably warm... yep, I'd forgotten to turn the oven off. For about two hours it had been valiantly trying to heat the whole room to 220C (or Gas Mark 7). This was reflected in my next energy bill. Ouch.
