Upon inspection, the American Breville kettles are 1/2 the wattage with a 1 liter boil time of 4 minutes at 1500 watts.

The UK versions from the same brand are 3000 watts, but only reduces the boil time by 1 minute.

I'm not sure about efficiency one way or the other, but it's interesting to note that double the power does not yield one half boil time.

Additionally, at this elevation I would estimate my morning coffee, Americano (Italian coffee that requires boiled water), takes less time to make than it would at higher wattage at sea level. I'm only guessing.

I think it comes down to practicality more than either culture's love of tea or coffee.

Yeah, come to think of it a coffee machine is solving a very similar problem to an electric kettle. Whats more, I’ve even used a drip coffee maker as a makeshift electric kettle before. So that was just a dumb argument on my part. Thanks for bailing me out with actual data on the diminishing returns of dumping more power into an electric kettle!
