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)
- Thorrez 4y agoHow 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.
- photonbucket 4y agoI don't know if it's significant, but there is also energy to physically move the gas to your location, for the second scenario
- thomas_ma 4y agoEnergy efficiency is going to be better with induction in that scenario since it only heats the food, not the pan, stovetop, etc. On top of that, the pollution is dramatically reduced. A modern natural gas turbine at a power plant is dramatically cleaner burning than an open flame in a kitchen stove.

Not to mention the pollution from the power plant is not going directly into your home (or face). This is not a small or hypothetical impact. From the article: > The air district estimated that the new rules for homes would cut nitrogen oxides enough to prevent 89 deaths per year in the Bay Area.
- adrianN 4y agoA lot of the heat of the flame doesn't end up in the pan.
- TylerE 4y agoWell, if you’re being fair you need to include how the gas GETS to the home.

- heleninboodler 4y agoYou also need to compare: * natural gas -> home furnace -> fire -> warm air vs * natural gas -> fire -> heat -> electricity in massive generator -> home -> heat pump -> warm air The latter is, surprisingly, something like 2x the efficiency because while large scale electricity generation from gas is only about 40% efficient, you can get a COP in the neighborhood of 5x on the heat pump. The part that isn't obvious is that the fantastical-sounding "5x" isn't really about energy efficiency but rather about changing the problem from "generating heat" to "moving heat from one place to another".
