There are many ways to create a more energy efficient kitchen, but few changes will make a bigger impact than addressing your major appliances. If your refrigerator, dishwasher or oven are more than 10 years old or aren’t energy star certified, it may be time for an upgrade. Older appliances may not run efficiently, wasting more energy in order to function day-to-day. While there is an initial investment cost, the savings over time on water and electricity can be significant. You’ll also give your kitchen a sleek new look with beautiful and modern upgrades. However, don’t stop with just purchasing a new item; make sure you maintain it and keep it clean. A well-cared-for appliance will last longer and perform more efficiently, so follow the manufacturer’s recommendations for regular maintenance.
