Mechanical energy because that's where all of the elements are I thought it was electrical energy but you said "gas stove" which makes it Mechanical energy because when the gas burns it burns the coal and turns it into ash and I thought it was thermal energy but then you said "power" which makes it mechanical energy.                                                                                                                                       Your answer is Mechanical energy.
