Cooking with less energy
I found this article about cooking using less energy. https://www.spsnational.org/sigmapisigma/radiations/spring/2019/making-g...
Pizza is used for the example, and energy inputs all along the line are taking into account, not just the energy used at the point of cooking.
I enjoyed the photo at the bottom of the page, where obviously it is not pizza being prepared. I see in the photo some energy saving items and wonder if you might be able to identify more. If I enlarge the photo, I see farthest from the camera a pressure cooker. Then I see a knife being used, which pleases me because so many cooking sources say to get out a food processer when a people-powered knife will do. There is a "Wonder Bag" type passive insulated cooker; perhaps it is homemade and filled with straw, or crumpled paper, shredded corrugated cardboard, etc. I think in the foreground the shiny tubular thing is a solar oven.
I don't know what some of the other things are. Can you tell me?
