I'm very environmentally conscious but personally I'm gonna switch to an electric vehicle and heat pump before changing my stove to an electric one I think. I will make sure to have proper ventilation when cooking though from now on, I wasn't aware of the health aspect of all the byproducts of cooking with gas.

To be fair. Your gas stove in your home can pose health risks due to often poor ventilation of the fumes. Your personal and childs health might improve by moving to induction.

True, I hope that being more mindful of ventilation, especially while cooking will have a positive short term effect.

While I am generally supportive of electrification efforts as a major tool in combating climate change, I am wary of having a single energy source to my house. Particularly in light of the grid failures in Texas last winter. We would have been in big trouble without uninterrupted gas service. Running a small (1500 watt) generator to power the blower and control circuits, we were able to heat the house and cook withou…

In all fairness the Texas grid failures were the result of intentional choices made by the Texas government. Other states with similar weather had nothing like the catastrophic failure TX had.

My father in law, a quite intelligent person with a non-technical background, asked me a really good question re: electric appliances and vehicles. He was holding off on getting an electric car, because he didn't understand how it could possibly be more efficient and cost-effective to use gas appliances in the home, but suddenly it's more efficient and cost-effective to use electric motors in cars. Of course the prob…

To add confusion; induction is drastically more efficient than resistance heating; heat pumps are drastically more efficient than gas or traditional heat. So the communication problem is also one of changing technology. Technologies that adults learned 30 years ago are not the same as those today.

Resistance heating is 100% efficient, how can inductive heating be more efficient than that?

Absolutely true. But redundancy is still a good thing.

I recently read that most fume hoods aren’t powerful enough to remove the worst of it, but can’t find my source.

Resistance heating is 100% efficient at heating the element, but to heat the pan, it has to transfer through the pan/element interface.

100% isn't the highest efficiency you can get though. It's even more efficient to use the electrical energy to concentrate existing heat than it is to create new heat

Outside is a really large heat sink. So you can dump unwanted heat or cold outside to heat out cool your house using a heat pump.

Resistance heating is 100% efficient at heating the world. Considerably less efficient at heating the one specific pot you are trying to heat.

Many hoods are ductless and recirculate the air after passing it through filters. I imagine these likely do nothing or close to it regarding removing the offending substances.

All but a very few instances of natural gas malfunctions (like a completely severed pipe) are safely mitigated by mixing and dilution.

Most common gasses are only dangerous in large amounts, when stratified and consentrated in a small confined space.

Which is why ductless hoods are able to meet code in the first place.

Ironically, this has become a bigger issue because of houses being more tightly sealed due to efficiency regulations. Old houses would naturally draw and vent in the event of any sort of out-of-equilibrium gas buildup.
