Cooking low and slow can be a cost-effective way to prepare meals. A recent study found that using a slow cooker or Instant Pot can save you up to 91% in energy costs compared to using an electric oven. The study used a pork shoulder recipe as an example, finding that the slow cooker used only 5 cents per hour, while the Instant Pot used about 17 cents per hour.
