Modern gas stoves, esp. in the EU has electronics for safety and relighting if it goes out. So they're not just a bunch of valves like the stoves of the yesteryear.

We use electric stoves for ~20 years and nothing has broken on them except a regular bulb back-light. Current stoves esp. BSH made are not solid state electronics. They are relay powered industrial automations so they don't break twice a week.

OTOH, most probably the landfill nearest to you is using methane trapping technologies to use that methane to generate electricity. Ours is doing it, and it's awesome.
