Americans don't really do electric kettles, largely on account of using 110V mains, which limits power to around 1100W, making it a lot slower than ~2000W electric kettles in the 200+V world.

Americans largely don't use electric kettles because Americans largely don't drink tea at home and thus don't use kettles as often as the rest of the world. Most households I know don't even own a kettle. Not a stovetop one, not an electric one. If you were to ask most Americans why they don't have an electric kettle at home they won't say "because I only have 120V outlets in the kitchen." They'll say it is because t…

You sure? Germany is a (shit) coffee country and everybody has had electric kettles since the 90s.

I'd be very surprised to see a standard US gas range capable of boiling water faster than an electric kettle.

Yeah, even for a 1200W kettle heating a liter of water can be faster in the kettle than an average gas stove and pot.

A better way to save energy is to use an electric kettle to get the water up to boiling. This is about three times as energy-efficient as a gas hob. Combined with passive cooking it could save real money… Technology Connections on YouTube has a good video about how electric kettles are the superior way to boil water: https://youtu.be/_yMMTVVJI4c

Alec, of the Technology Connections YouTube channel, shows it's not just energy saving, but faster and cleaner. Even with US outlet power limits a kettle will boil a volume of water much more quickly than a gas stovetop, and my indoor CO2 sensor won't spike by hundreds to a thousand PPM of CO2. While the time savings is modest, if you have an electric kettle it's a no brainer to prefer that over gas. Though induction…

Your gas stove will likely dramatically outperform an 1800W electric heater if you use a proper pot:

I would still rather use a nice induction range, but it is possible to get decent efficiency out of gas.

Not sure what's so special. I would assume everybody knows that most of the energy during cooking is wasted: 1. By the water evaporating 2. By the hot gasses escaping without actually heating up anything 3. With the water poured away after cooking Which is why I: 1. Put a lid on the pot whenever I can. Once it boils it usually is enough to reduce the burner to absolute minimum to keep the simmer unless I am adding la…

Steaming does take a bit more time but I think it is still more efficient than poring huge amount of water into the pot. Pressure cooker my friend! Chemical reactions at 115C will by ~3-4 faster than at 100C. In my opinion, electric grids should give away free instant pots as a part…

What? This much, really? TIL, thanks! I never use ours (too large), but will try to adapt using it.

This is not just efficient but also saves a lot of time. I do this with rice/pasta or anything that requires boiling. Also, using a pressure cooker can save a lot of time/energy with foods like legumes/meats etc.

+1 for pressure cooker. I use mine twice a week or so. For just about anything since there are so many recipes online. And less clean up!

No mould will grow on soaking (i.e. submersed) rice.

Confidently dismissing someone else's firsthand experience, exactly the level of intelligent conversation this site is renown for.

Yes, much better to blindly believe an anecdote that contradicts known food science.

And here I was imagining that the Barilla passive cooker would be a thermal cooker -- a vacuum-insulated sleeve for a pot that can hold cooking temperature for hours. Several companies make these.

The claim: reduces CO₂e emissions by up to 80%* The asterisk: water boiling phase excluded When I boil pasta, I use full heat to get the water boiling, drop in the pasta, then let it come back up to a boil, then drop the temperature as low as possible to keep a slow boil going--about medium-low. Guesstimating that the boil takes about as long as the time to cook the pasta, I'd say that the pasta cooking portion only…

No it's not.

The most efficient (and fastest) way is an induction hob with copper disc pan. Something that Technology Connections didn't include in his video.

It’s not that slow. 1. They sell plenty of kettles in the US (touch grass and go to Target sometime or something) - a large portion of those sales are probably to Asian households. It is simply that if you have a drip coffee maker and don’t drink much tea why do you need a kettle.

No idea where this dumb myth comes from - kettles are not hard to find in the US, they work fine - there is a ton of demand it is just relatively miniscule.

This is the epitome of what is - unfortunately - wrong with capitalism.

Lofty claims of CO2 saved, while the marketing and production of a single device alone emmitted X times of cooking pasta without it.

Makes me truly question if technology & capitalism, for all the massive good they have achieved so far are the solution or our doom.
