High-efficiency appliances are designed to use less energy and water compared to standard models. They often carry the Energy Star label, indicating they meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. These appliances can include items like refrigerators, washing machines, and dishwashers. Using high-efficiency appliances can lead to significant savings on utility bills over time. They not only help reduce energy consumption but also contribute to a lower environmental impact by decreasing greenhouse gas emissions. Investing in these appliances can be beneficial for both homeowners and the planet.
