When you are making a cup of coffee, tea, or other hot item, only boil the amount of water you actually need. This will save time, use less energy, and save water. It also saves you money. Boiling too much water costs households millions in unnecessarily high energy bills.

• This action is easy. Simply, fill the mug/cup/container you want to use with cold water and then pour into your kettle to get exactly the right amount.

• When you pour the boiled water back into the cup you've got the perfect amount so you do not need to worry about over-filling!

• Boiling water on an electric stove is the most efficient, followed by a microwave, and then methane (natural gas). That is especially true if you electricity is powered by clean energy because natural gas is always more polluting than clean electricity.
