A surprising number of gas stoves do not work without electrical power. It's supposedly for safety reasons because a user might leave the gas on after the electronic igniter fails to fire. Of course, it's possible for a sufficiently incompetent user to turn the knob past the light position and achieve the same result when it does have electrical power, so this feature strikes me as nonsensical. I had an annoying experience with this during a multi-day outage in Alaska last year. We did have other options including a generator, but I'm not a fan of being patronized by an appliance.

Why is that a feature? ...interesting :) Our stoves here usually have some heat-based protection, where you have to hold the knob pressed in until a tiny rod heats up (usually 2, 3 seconds) and after that you can release it and the gas will stay on. Without power, you just need a ligher (or anything releasing a spark) to ignite the gas. Also, the default configuration for gas stoves is 3x gas cooktop + 1x electric, so most people are covered in both cases.

  I've used the design you're describing with a heat-based valve, and it's definitely superior. I've never seen a cooktop with both gas and electric - is this redundancy in case one service or the other is interrupted?

    I have no idea what the reasoning behind it was then, but it was a standard carried over from yugoslav times (usually 3 gas + 1 electric or 2+2) :) So yeah, could be redundancy... https://i.imgur.com/rHDaZxm.png https://i.imgur.com/rHDaZxm.png <- something like this was standard, also back in the time the colors were browner ( eg. https://i.imgur.com/RJkq5GK.png https://i.imgur.com/RJkq5GK.png ) :) The modern variants look more like this: https://i.imgur.com/iJvKQjy.png https://i.imgur.com/iJvKQjy.png or with inductive heat instead of resistive: https://i.imgur.com/BOetXJz.png https://i.imgur.com/BOetXJz.png I remember only one gas outage (some repair work done somewhere and they closed the valves) but there were quite a few power outages, where you had to use a lighter.
