Do you think you can make a difference during the daily coffee-making ritual? Well you certainly can. Next time you are boiling the jug, check how much water is in it and only boil the amount of water that you need to make the required number of tea or coffees.
What difference does this make? The amount of water in the kettle determines how long the kettle needs to be running to boil the water. So the more water you have in the jug, the longer it takes to boil the water, the more electricity is required and more resources are needed to supply the electricity to your house.
Make a difference, boil only the water that you require.
