Given that heat pumps and other technologies have proven themselves quite well at this point it is not a bad idea for SF to lead the country on this one and shows that one can electrify most stuff (if not all stuff)

Yep, until the next earthquake or forest fire or another natural disaster happens and your power goes out. Then you are out of luck to cook, and/or warm yourself. Relying on one type of energy source is a single point of failure.

Hope their electricity isn't being generated with natural gas

This code would be about home appliances. But it turns out that massive generators are pretty efficient since they can operate at a huge scale. So even if the electricity replacing the gas stove was generated with gas, it'd still be better for the environment (and human health)

How does the efficiency of

* natural gas -> fire -> heat -> electricity in massive generator -> home -> induction stove -> pan

compare to

* natural gas -> fire -> heat -> pan

? And resistive is worse than induction.

Good luck getting natural gas service after an earthquake severe enough to knock out power. Natural gas lines are far more at risk of breaking during such an event, and the gas utility will usually shut off gas supply until they are sure there aren't major leaks. After an earthquake, you are supposed to shut off your own supply at your meter with a gas wrench.

> The rules would essentially require all new residential construction to have electric water heaters by 2027 and heat pumps instead of furnaces by 2029. By the time this is fully in effect for a significant number of people (i.e., basically the 2030s), yeah, the electricity will be pretty green. The target is 90% renewable electricity by 2035, and the mix was already around 34% renewable in 2021 statewide. It seems…

Why are people so attached to gas stoves when we have induction anyways? I love to cook and have a gas stove, but I bought my parents an induction unit a while back. Sure it can't provide an open flame, but the ludicrous speed at which it heats things up vastly outweighs that drawback. And not having to worry about ventilation nearly as much as just a bonus. My range hood needs to be on full tilt when I cook over lon…

> Why are people so attached to gas stoves when we have induction anyways? People are attached to gas stoves because the usual alternative you see in rented units is shitty electric stoves bought at the lowest cost, not induction.

As an SF apartment dweller, this is my main concern.

My apartment has a shitty stove, but you know what? At least it's gas.

If it gets replaced, I am 110% sure it will not be with a nice induction stove. It will be with the cheapest electric stove that's available.

My house is already maxed out on electric capacity because I have an electric car. I've investigated increasing the current coming into the house, but changes in code mean that making that upgrade would cost $20K. So if my hot water breaks, it will cost me $20K+ to fix it. That's not reasonable.

It'd be quite a talking point if this forced you to get an ICE car again

Don't forget the government wants to drain your car battery each night to deal with all the new load this is going to generate. :)

Because cooking with gas provides more, and better, temperature control than even very expensive induction setups. If you stir fry, there is no comparison. Also, low temp induction sucks. Even good units do low-frequency PWM to approximate low heat settings that come naturally with gas. Induction is a big step forward compared to the older, resistive-style electric elements, and there's a lot to like about it. But wh…

Haven’t tried stir frying yet (and I’ve read claims that any home and even restaurant wok burner can’t match the flavour from the very high-power outdoor gas burners used on the streets of Asia) but low temp induction works just fine, thanks. My $50 Ikea hotplate does a better job at very low heat than our gas burners, on-off cycling and all.

Indeed, if you’re keen, you can buy specialist induction hotplates with connected thermometer probes that can give you way more precise control than gas ever could. Pricey but if you’re into fancy stuff like tempering chocolate they are excellent.

when the power went out for 5 days two weeks ago, I could run the entire house on a $1200 generator. The gas furnace (600 watts), gas stove, gas dryer, and gas water heater used very little electricity. At some point Ill connect the generator to the natural gas line too.

My friend with a brand new heat pump could not run the heatpump off his generator (6kw).

I do like induction and use an induction hotplate for a few things and actually wouldnt mind having an induction stove with a small propane stove for when the power goes out.
