Cutting the cost
Only boil what you'll actually pour. A kettle filled to the brim wastes most of its heat warming water you'll tip away, so fill it from the cup you're about to use. Descale it now and then, since scale on the element slows the boil. And an electric kettle heats water more efficiently than a pot on the cooktop.
