Energy-efficient refers to using less energy to perform the same task or produce the same result. For example, LED light bulbs use significantly less electricity than traditional incandescent bulbs while providing the same amount of light. This means that homes and businesses can save money on their energy bills and reduce their impact on the environment. By choosing energy-efficient appliances, like refrigerators and washing machines, consumers can lower their energy consumption. Many of these appliances come with an Energy Star label, indicating they meet strict energy efficiency guidelines. Making these choices not only benefits individual households but also contributes to a more sustainable future for everyone.
