Use pieces of wood of different thicknesses, a set volume of water, and a small pot.

Test & time how long it takes the water to reach a rolling boil.

a difference of 1-3% could be significant in expenses over a year but would be hard to detect reliably in home experiments without going for countless tests

1-3% still isn't much, because that's only the net power used by the induction plate, vs your total daily power usage.

If you have a desktop computer & graphics card, that's probably eating more of your power.
