use the smallest pan possible on the smallest ring and use the pan lid - you'll need less heat
heat water in the kettle and then transfer it to the pan on the hob - its quicker and more energy efficient
slow cookers are much more energy efficient than the oven (they use about the same amount of energy as a light bulb)
batch cooking in the oven, rather than turning it on for one item at a time
clean the glass in the oven door, so that you can see how your things are cooking rather than opening the door and letting the heat out. Turning it off 10 minutes before then end of the allocated cooking time, will allow you to make use of the residual heat
boiling the kettle full for 10 minutes a day costs £27 per year - only boil as much water as you need.
