out of interest, is stove top more or less efficient than electric?
is that even possible to quantify?
answered my own question
Electric kettles are slightly more energy-efficient, coming in at around 80%, vs 70% efficiency on the stovetop. However, this is evened out by the fact that gas is cheaper per unit than electric. Then you need to factor in the fact that stovetops take longer to boil water vs an electric kettle. On balance, it probably works out roughly the same, but perhaps slightly cheaper to use an electric kettle.
