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.
