I try to resist the urge to turn off the heat immediately before serving food because the pan is still hot for tens of minutes – all wasted energy. I try to turn off the heat ~10—15 min before the food is done cooking. Most people are impatient, addicted to convenience, lack self-control, and probably don’t even consider the wasted energy.
Electronic pressure cookers at least steer people toward using residual heat because when the cooking is done pressure protections block access to the food until pressure drops. OTOH, that’s due to temps being higher to begin with (above boiling).
Anyway, cooking food is rarely critisised as a significant climate factor. But you have to figure 8 billion people worldwide are wasting energy in this same way on a daily basis. Maybe it should be studied?
LED are a massive reduction in power consumption. You can feel the difference, even in a 25w bulb.
My 1600 lumen led bulbs put out less heat than a 25w incandescent, yet are the light equivalent of a 100w+ incandescent.
LED are typically about 10% the power consumption of an equivalent incandescent. And today you can get color-selectable LED.
As a bonus, all of the ones I’ve tried last way longer than incandescent bulbs, by a huge margin (at least 5x longer, some far more).
LED’s are awesome! I replaced my bathroom lights when I got into this apartment, that saved me 90 watts. And this may be unusual, but those are on for about 8 hours a day here
