MODERATORS
That depends on how well vented they are. Most people undersize their range hoods for aesthetics and don’t take venting seriously. Of course recent findings show it’s a bad idea to cut corners on that with gas stoves, and ovens to some extent. But it’s mostly stoves that have the issue you describe.
While they are less of a problem when they’re better vented, they’re still a really big problem. You can’t possibly vent them well enough.
Still sounds like you’re talking about stoves. To use a stove, you inherently need to stand next to it and your face is between the flame and the vent. Ovens are well insulated (this is important for energy efficiency), they vent to the outside, and you are not generally standing over the oven throughout the baking.
Where do you think the oven vents its exhaust gases to? The outside? So you have an exhaust vent directly attached to the oven? Which model of stove does this? Most of them vent into the range hood like the stovetop, or just into the room.
Let’s give a better example…. A well vented stovetop…… and you burn something on it really badly….
Does the vent catch ALL the burning smell? Or does the kitchen still smell of burnt food?
Yeah, that smell is the gases and particles that the venting didn’t catch…… there’s still a fair bit, isn’t there….. can you smell the burning?
The amount of gas that’s healthy for you to consume is basically zero, so even if the range hood catches 90% (I think it’s closer to 60, but I don’t have a source on that), there’s still a lot in the air.
K, so put the condescension away when you can do these experiments at home with the help of a responsible adult.
I think they're talking about ovens in the kitchen, not heating with gas.
Oh, thanks, now I see.
Was it always the case though? You should probably roll back to data in the 70's for wider house appliance rollout. Then if it's not a thing for a generation, it's never gonna be a thing. For today, electricity is easier to decarbonate I guess
That's it. Gas used to be cheaper.
Why do you say that in the past tense? You can see from my figures that in Belgium gas is still cheaper.
This is something that varies from one region to another. In the US, some states have cheaper electric than gas. Electric is less efficient because of big losses in all the conversion steps:
fuel energy → heat energy→ steam → turbine → transmission → heat energy
Gas simply has:
fuel energy → transmission → heat energy
It is important to note that gas transmission is also lossy due to the impossibility of leak-free main lines, but it’s still more efficient in the end. Thus in most of the world gas is also naturally cheaper due to the efficiency difference. It gets inverted in some regions because of pricing manipulations as well as the drive to promote green energy (and rightfully so -- social responsibility should be incentivized). And in some regions they cut down on the transmission losses by putting the power plant inside or close to the big city. But in Belgium gas is still cheaper than electric even despite Russia’s war and efforts to get off Russian fuels.
Your mistake is assuming electricity always comes from fuel.
Electricity is usually not made from fuel, though, but from a wide variety of resources. And you forgot the last step – transmission of heat from the stove to the food. Gas stoves are far inferior in this step, losing most of the heat into the surtounding air. Induction stoves have almost no transmission loss.
Another reason is installation. In order to use gas in the kitchen, you have to have a gas pipe in the kitchen, which has become very unusual. During construction, it's easier and cheaper to not lay gas pipes. Most people do not have a choice – either you got an old house witha gas pipe in the kitchen or a newer one with a 400 V power outlet.
