> Where's the energy loss from the kettle that's not present in your proposed method?

You're not heating the water directly, you're heating it through a piece of metal. The wasted energy is heating that piece of metal up to more than 100 deg C. A surprising amount of energy lost there.

If you use the induction hob you're only heating the metal that you actually need to heat to do the cooking.

For us in northern climates, none of this energy is really wasted during winter. But many of us now have heat pumps, which are more efficient than resistive heating.
