Not sure if this has been scientifically studied but I’ve noticed a couple situations where continuous heat can be avoided.

My mom’s way of cooking corn on the cob: bring a pot of water to boil, lid off with two wooden spoons resting on the top to prevent boiling over. She keeps the heat continously quite high for what, ~30—40 min? Seems wasteful because with the lid off the pot is evaporative cooling the whole time so more heat is needed to offset the cooling. I just tried it this way: bring to boil with lid on. Shut the burner off as soon as it boils. The corn continues cooking as the water temp drops. I could probably improve on that even more by using a pressure cooker. (I’m stalling on buying one because I boycott InstantPot due to the fact that they have a closed source phone app exclusively in Google Playstore; it’s optional but InstantPot buyers are still financing that. I should probably get a 2nd hand manual pressure cooker).

Hydrating dried beans: soak overnight (which I skip because it seems to make little progress). So I do the “quick soak” -- bring to boil with lid on, turn off right away, and let them sit ½ the day in warm water. Pressure cooking speeds up the 2nd stage cooking for sure (I’ve tested with other people’s pressure cookers). Since I don’t have a pressure cooker, I end up doing the quick soak method ~3 or 4 times throughout the day.. which just means bring to a boil then shut off. Anecdotally this seems to reduce the time needed in the final phase of cooking.

Am I going OCD on this? This all might be a drop in the ocean.. cooking is not a significant portion of energy consumption. But maybe notable in the summer when cooling systems have to work against the kitchen heat. Which is one reason I like the electronic pressure cookers: I can set the pressure cooker outside.

Here to second the utility of electric pressure cookers, Instant Pot or other.

Best rice cooker I've done used and it speeds up cooking so many things. I cook a LOT of curries in it and it seriously reduces cook times and therefore I'd assume energy use. Get a bigger one if you do meal prep. I can make a month's worth of sambar in one go, quarter the batch, freeze 3, and defrost 1 week's worth at a time.

I make one curry like this every other week or so I have a variety of meals ready at any time.
