Today's tip is pulled from an amazing organization across the pond called We Are What We Do. In the land of the tea-drinkers, kettles are electric, and they say: "Only fill your kettle with the water you need. If everybody did we could save enough electricity to run all the street lighting in the whole country."
It's true. And it relates to more than just tea! Boiling water for pasta or potatoes? Why fill that pot all the way up? It's only going to take longer to boil, and you'll probably have your bowties floating around in way too much water. The longer it takes, the more energy you use!
