Energy labels are stickers or tags found on appliances and products that provide information about their energy efficiency. These labels help consumers understand how much energy a product uses, allowing them to make informed choices when purchasing items like refrigerators, washing machines, or light bulbs. The labels typically feature a scale from A (most efficient) to G (least efficient), making it easy to compare different products. In addition to energy efficiency ratings, energy labels may also include information on estimated annual energy costs and environmental impact. By choosing products with higher energy ratings, consumers can save money on utility bills and reduce their carbon footprint, contributing to a more sustainable future.
