Energy labeling is a system that provides consumers with information about the energy efficiency of products, such as appliances and vehicles. These labels typically display a rating scale, often from A (most efficient) to G (least efficient), helping buyers make informed choices that can save energy and reduce costs. The purpose of energy labeling is to promote energy conservation and reduce environmental impact. By choosing products with higher energy efficiency ratings, consumers can lower their electricity bills and contribute to a more sustainable future. Energy labels are commonly found on items like refrigerators, washing machines, and light bulbs.
