IH cooking is so economic, just read article comparing the gas range and induction cooking for a simple pancake making.
The bad thing about IH cooking is that you have to use a certain metal bottom for your pan and cookware. For instance, if you wanting

enough heat. So ideally, it is best having the regular propane/NG heating device along an IH cooking source.
