I assume he was saying that a new kettle is more energy efficient than an old one, which unless you have something from the 90's or earlier then it's not true - I've been flogging them for 20 years and there's nothing innovative launched in that time. If he was really bothered there are a couple of things he could have said which will save money for people in that area. Firstly only boil what you need - a lot of people fill the kettle to the top and then boil it so essentially you can be boiling 6/7 cups of water you don't need. Secondly you don't need to reboil again because you've walked away for 5 minutes - again a habit a lot do. Thirdly descale your kettle as limescale on the element will increase the time to boil
Surreal.
