Small habits - big differences

My sons former girlfriend went through a phase of doing our laundry and dish-washing. Very kind so I didnt complain but since she isn't here anymore I have started to do it myself my bills are down so much. So, with all things electrical, I play by the rules

• Only use the tumble dryer when its largely unavoidable - I don't dry indoors as when I did this previously it made my house very damp and I dont use heating until it really cold, so it would be a waste to heat it just for the drying.
• Dont set the dishwasher going unless it is full
• Dont set the dishwasher going unless it is stacked in such a way that everything will come out clean
• Dont set the washing machine going until it is full but not overfull.
• Give everything a good spin before drying.
• Even if it not a sunny day then you can still get a bit of drying done. 
• Put shirts etc on coathangers to bring them in quickly.  
• Fill the 'clothes horse' with towels, jeans etc and you can lift it indoors in one go if the rain starts
• Hang your undies on an octopus (multi hanger thing) and again you can grab it and bring it indoor in no time.
• Drying that is already partially dry can be finished in doors, unless its really cold and damp, without making the house damp.
• Dont use the electric oven to cook things which are perfectly good in the microwave or in a dry griddle pan.

Any one have any further ideas to brings the bills down?
