They are definitely better in appealing to first time buyers who may not know or care about their shortcomings. They look great and are easy to clean. But if you are into cooking, gas wins.
With induction, ~90% of the energy from the electricity is used for cooking while only 40% of energy is used using a gas cooktop. Induction is more efficient, and you can use a wok if one is purchased that is designed for use with induction. Induction units can also regulate themselves based on feedback from the cooking device on the receiving end.
Induction is arguably superior to cooking with gas.
> On almost all counts, induction is faster, safer, cleaner, and more efficient than either gas or electric. And yes, we've done exhaustive oven testing in our labs to support that claim.
Yes induction is efficient if you only look at the part inside your house. But most of the losses are outside your house.
If you live in a place with advanced wind or solar power like South Korea then electric probably is more efficient.
It's wasteful to spend money on gas infrastructure when it's clear electrical distribution is the future of home energy use. Infrastructure dollars are already in short supply. Just my two cents.
EDIT: You can stockpile energy with batteries, which is the likely outcome based on how much battery manufacturing capacity is coming online to build hundreds of thousands of EVs a year (which are also a great buffer for renewables and electricity in general).
Maybe for cooking with a wok. But around here most homes are heated with natural gas. And that takes a lot more energy then heating chicken and vegetables.
New natural gas furnaces are up to 97% efficient. They're no longer allowed to sell furnaces that are less than 78% efficient.
To your point, you can purchase very efficient gas furnaces, but they're more expensive and require a retrofit of the flue pipe to PVC due to corrosive properties of high efficiency furnace exhaust (not a concern in new construction).
Air source only heat with a heat pump is a slam dunk anywhere south of the 36°30′ parallel, and all of California.
We can stockpile natural gas, which is mostly methane. And we can figure out how to make methane without fossil fuels.
They're none of that, although they are less flexible than gas.

They're safe, efficient and convenient for people who want to make food.

If you're one of the people who believes they need gas to survive, you can buy bottled gas for your range.
