What causes power outages

Power outages can happen at any time. That’s why we’ve outlined what causes electricity to fail and who to contact when the power is out.
There’s nothing as simple and comforting as putting on the kettle and sitting down with a hot cup of tea. The science behind how it works is really quite straightforward too.
In part three of our ‘how stuff works’ series, we take a look at how electricity powers our kettles.
When gas cook-tops became more widely available around 100 years ago, the whistling kettle, otherwise known as a steam kettle became a popular kitchen appliance. The premise was simple, water in the kettle would boil, building pressure which was forced through the lid, releasing a high pitched whistle1.
By 1922, steam kettles were replaced with electric kettles, invented by Arthur Leslie2.
Russell Hobbs then manufactured their K2 kettle in 1959, which featured a cool-touch handle and lid, preventing people from burning their hands3.
If you’ve ever wondered how kettles work, we’re going to break it down for you.
Inside each Kettle is a metal coil. Electrical energy travels through the coil, turning into heat and warming the cold water inside it.
The process looks a little something like this:
Kettles are already 50% more efficient than stovetops when it comes to boiling water, but you could save even more energy by avoiding these three common mistakes:
Did you know that kettles run more efficiently when you clean them once a month?
