I assume I'm just being dense, but if you have to boil the potato, surely that takes a bunch of energy? Or do you burn wood to do that in this scenario
For example, one may argue in a given situation one should use an induction cooktop from an efficiency standpoint (and also particulates reduction). Another may argue in a given situation one should use a woodstove if they can source the wood in a sustainable manner and can create maintain the woodstove itself locally. Not asserting a right answer here, just outlining some tradeoffs.
