The first monthly energy saving tip is this. A kettle boiling for one minute longer than it needs to uses a similar amount of energy as leaving a light on all night, so, to ensure you don't boil too much water fill the cup up and pour the water from the cup in to the kettle, repeat for however many cups you are making.
Simple and effective, it'll also mean the kettle boils quicker!
