I don't know why you're downvoted.

Induction hobs cut out a loss leader for gas: gas stoves. Once you have gas in your home it makes sense to install the main moneymaker: a gas furnace for heating. It's how they upsell.

Induction hobs are great in the fight against global warming.

If the energy you use for heat is generated by gas, it's more efficient to burn it directly, and the emissions produced from manufacturing all the new stoves likely out way the emissions produced over the stoves lifetime.

So, I'd say it's only helpful if you are getting a new stove anyway.

Of course, one also has to consider the leakage of methane that occurs with all the residential natural gas distribution, which is significant. Methane being 25x the greenhouse potential of CO2 means there's a lot of hidden environmental impact.

Stoves have to be replaced at some point, especially when doing renovations or rebuilding.
