I often wondered. On an induction burner if it takes as much energy to heat something as say a regular contact burner or gas burner if talking BTU?
Induction is far more "efficient" in that the amount of electricity consumed vs what percentage goes into directly heating the metal is very high. i.e. there is little electricity lost as waste heat etc as it is being converted to heat in the metal of the pan. That said, electricity is far more expensive here that gas, so I am not sure I will see any actually noticable bill changes TBH.
So, a more direct answer to your question is "The amount of gas or electricity used (much of it wasted to the surrounding surfaces and atmosphere) in heating a pan using traditional cooktops is considered to be much higher..." everywhere I have ever read....we are just considering moving from gas to induction right now and I've been exploring the topic.
We want to move to induction mostly because there is so much heat on our gas stove lost to the exhaust fan, and along with that we create so much excess grease in our kitchen from the rising heat - it is really horrible. I love cooking with gas, but the side effects are really pretty bad for both home and health unless you aggressively exhaust...
I also kinda hate my gas oven...it's too "moist". I would prefer an electric that is more insulated as well. I can almost heat my entire house when the gas oven is on for a bit on high temps...so much heat leaving the exhaust vent it is crazy.
