If you own an electric range, here’s a way to use just a little less power without expending any effort at all:
Use the correct burner.
This seems like a small thing — and it is — but it takes zero effort, there’s absolutely nothing to be gained by not doing it, and if it shaves a penny or two off your power bill, why not?
Most electric ranges have four burners — two large and two small.
If you’re cooking something in a big skillet or stockpot, use one of the big burners. If you’re cooking something in a small skillet or saucepan, use one of the little burners.
If you’re not sure which size is best, before you turn on the stove, set your pan on a big burner. If you can see the burner sticking out around the bottom of the pan, move to a smaller one.
If you’re using a large pan, it makes sense to use a large burner. You want the bottom of the pan to heat evenly, and you don’t want to end up throwing food away because it didn’t cook right. But when you use a small pan on a large burner, you end up heating more of the cooktop than you need. According to the American Council for an Energy-Efficient Economy’s website, SmarterHouse.org, using a six-inch pan on an eight-inch burner wastes more than 40 percent of the electricity produced by the burner. (Bonus points if you can figure out how they arrived at that number.)
Food won’t cook faster or taste better if you heat an inch of empty space all the way around the pan. That hot surface protruding from under the edge of the pan just wastes energy and creates a hazard in the form of an exposed hot surface.
SmarterHouse offers several other good tips on saving energy in the kitchen, such as using an appropriately sized pan (putting a big pan on a big burner to cook a little bit of food is no better than putting a small pan on a big burner), keeping your appliances clean and well-maintained, and considering which appliance is most appropriate for whatever you’re making. I’ve touched on some of that in previous blog entries, but SmarterHouse goes into more detail. I think it’s well worth the time to click on over to their site and look around.
