Why do you say that in the past tense? You can see from my figures that in Belgium gas is still cheaper.
This is something that varies from one region to another. In the US, some states have cheaper electric than gas. Electric is less efficient because of big losses in all the conversion steps:
fuel energy → heat energy→ steam → turbine → transmission → heat energy
Gas simply has:
fuel energy → transmission → heat energy
It is important to note that gas transmission is also lossy due to the impossibility of leak-free main lines, but it’s still more efficient in the end. Thus in most of the world gas is also naturally cheaper due to the efficiency difference. It gets inverted in some regions because of pricing manipulations as well as the drive to promote green energy (and rightfully so – social responsibility should be incentivized). And in some regions they cut down on the transmission losses by putting the power plant inside or close to the big city. But in Belgium gas is still cheaper than electric even despite Russia’s war and efforts to get off Russian fuels.
Electricity is usually not made from fuel, though, but from a wide variety of resources. And you forgot the last step – transmission of heat from the stove to the food. Gas stoves are far inferior in this step, losing most of the heat into the surtounding air. Induction stoves have almost no transmission loss.
Another reason is installation. In order to use gas in the kitchen, you have to have a gas pipe in the kitchen, which has become very unusual. During construction, it’s easier and cheaper to not lay gas pipes. Most people do not have a choice – either you got an old house witha gas pipe in the kitchen or a newer one with a 400 V power outlet.
