Update: Lloyd also covered this issue over at Planet Green, pointing out that very few Americans have electric kettles, whilst 95% of brits and canadians do. As electric kettles convert 80 percent of the energy into heat that boils the water, while a kettle on the stove is only about 40% efficient and a microwave about 55 percent, it would make sense to make the switch if you haven't already.
We briefly mentioned it in our guide on How to Green Your Coffee and Tea, but the Guardian’s latest Tread Lightly pledge of only filling your kettle with the amount of water you actually need is certainly a useful way to reduce your energy consumption. Sure, it’s not an act that’s going to reverse climate change by itself, but if we can’t get the small stuff right then there’s little hope of cracking the big challenges. And in the UK, a nation that apparently guzzles 125 million cups of tea a day, the savings would be significant if the practice caught on among the general populace:"The EST concluded that if we each boil the water we need to make a cup of tea instead of filling the kettle every time, we could save enough electricity in a year to run nearly half of all the street lighting in the country. So this week's pledge aims to contribute to doing just that."
