My question, is it just a ridiculous analogy because there’s no such thing as an energy efficient kettle?
Only behaviour change with people heating exactly the amount of water required rather than overfilling kettles will reduce energy consumption, people are just going to have to be told to be more frugal and be careful when using appliance to ensure they are being energy efficient.
maybe buying a taller thinner electric kettle, so the minimum load is less, or indeed putting the kettle on the gas ring.
I do recall from O level mocks contention about a question involving the energy used to heat a kettle with a given layer of chalk inside providing some thermal insulation.
Pretty much half of the class solved it with heat on the outside going in, in the manner of a gas ring, and half the class assumed the heat from within like an electric kettle. The teacher -clearly the all modern miss with an electric kettle- was a bit surprised to be told there were 2 valid solutions.
In the intervening short time (ahem three decades, Mike), I suspect most households no longer have a kettle for the gas hob.

Still made and sold though.
