It also seems like a bit of a weird reason to me as a big reason. But maybe you get a lot more power outages than I do. (I would imagine somewhere with a gas main, where gas heating can be economical, would not have very frequent or problematic blackouts. With no gas main, you use butane/propane which is not so economical). Plenty of people have camping stoves lying around which can be used in a pinch.
My gas furnace will not ignite without power and the power necessary to run the blower is 15 amps or so, wiring in a portable generator would be simple.
The water heater works without any power whatsoever.
The stove has electric ignition but you can light it without power. The oven needs power (I think? never tried it).
Gas is also often more reliable than electricity as gas is practically always buried while electricity has many overhead lines in the mix.
My water heater does, but the little recirculation pump on it doesn't so it takes longer to get hot water at a distant faucet.
My central heat does not.
Yes. The gas stove does not need any electricity, same for the gas water heater. It's nice to be able to cook and have hot water showers during blackouts.
The gas furnace does require electricity to run the fan, but it's not much. So running the furnace to heat the house during a blackout is easy to do with a small generator to power the fan while all the heating BTUs come from gas.
Here in PG&E land (might be the most expensive electricity in the country, but at least it's the most unreliable!) these are nice advantages.
Practically all of the US has some renewable mix, so all the US already away from fossil fuels generating "all" the electricity (renewables + nuclear being 0%).
Over 30% of the electricity in my home is from wind and solar alone.
You also really shouldn't be using your stove to provide warmth in your home since you're probably not venting out the NOx, CO2, and CO emissions. CO poisoning kills a lot of people doing what you're claiming is a benefit.
So while I fully believe your lived experiences and preferences, a relevant question is: why are your electricity supplies so unreliable that having gas as well is even an important concern?
I don't understand the claimed causal relationship.
FWIW, I'm paying rent for my current apartment, we don't have a gas supply, and I've never had a power cut.
Indeed, while I am rich and do own an apartment back in the UK, roughly three quarters of the 16.5 years since I've last experienced a power cut was in property I pay rent for, and only about 4 years were in the flat I own and began collecting rent on when I left the country. Which, ah, also doesn't have a gas supply.
In any case, not sure what this is suppressed to have to do with reliably of the electricity supply — it's not like landlords get free shares in local power grid companies (or if we do, I missed the memo).
Sorry but this is nonsense. Your local power utility monopoly is what it is, completely unrelated to whether you rent or own.
Might be different in the UK.
I have never lived anywhere where blackouts weren't fairly regular. Currently in the backwaters of silicon valley and blackouts are the norm every time it rains, or there's any wind. Or forecast of wind or fear of rain. Thanks PG&E.
Probably depends where you are, as this is very much not the case for everyone.
We can't build new stuff which is practically obsolete on day 1 and a burden just 10 years from now.
