> In the winter, the gas stove will be more efficient since all the heat that doesn't go into your food, heats up the room (heating is typically also based on gas in the Netherlands, so this is basically free energy).

The efficiency loss of the electric kettle also gets converted into heat that heats up your home, energy doesn't just disappear.

Not the waste heat from the power plant.

As with everything in this discussion, this also depends on where you live as district heating is a thing

An electric kettle is ~90% efficient, the rest is lost to the surroundings but the electricity generation (assuming gas) is ~60% so the entire process, gas to hot water is ~60% and most of the waste you don't get the benefit of.

And gas stove kettle is ~40% efficient but you get the other 60% back as heat in the surroundings, so the entire process is ~100% efficient.

Assuming you need that waste heat of course. In the summer that 60% inefficiency really is an inefficiency.

Well the heating with gas is cheaper than with electrics in most places.

So it is "heat your house by X at price of the gas heating" vs "heat your house by X at price of electric heating". And the price of old school resistive heating, not the more efficient heat pump.
