Here's an old but simple tip that saves energy, time and money...
If you find yourself boiling the kettle several times a day just to make one cup of tea, what you should do is boil a full kettle first thing in the morning, use whatever you need for your one cup, and then pour the rest of the boiling water into a (good) thermos flask to use throughout the day. Saves time, lecky, and moolah!
If you don't fancy the thermos flask option, you should buy an eco-kettle, which has a special feature that allows the user to fill the kettle to its maximum, but then allows them to boil one to eight cups according to their requirements. Details here:
