    Yes all the energy goes into being heat but you have to put a lot of energy into the wire before it heats up. Microwaves barely use any energy in fact it takes more power to run the little clock than the microwave itself.

      That’s insanely untrue. Microwaves are power hogs up to a 1000 watts or more in some cases. The difference is the heat transmission method. The conduction of heat in a kettle is pretty slow because it forces the heat to propagate through water via convection, which is slower, while the radiation of a microwave antenna distributes the energy more evenly and faster. Consumption is mostly on par but energy transfer differs.
