Every kitchen owner should know energy efficiency is important, not only to lessen their energy cost of living but also reduce their energy consumption. By measuring and tracking a kitchen appliance’s energy usage, users are able to identify opportunities where energy and money can be saved. To do this, the first step is to calculate energy costs for all appliances in the household. Generally speaking, larger single-use appliances such as an oven or refrigerator use more energy than multiple-use appliances such as microwaves or dishwashers. Then, compare the energy costs of these appliances with energy fees that have been set by your energy provider.

With a bit of preparation and effort, you can make running your kitchen as efficient – and affordable – as possible!
