What is meant by "energy-efficient lighting"?

• A. Lighting systems that require more energy for the same illumination
• B. Lighting systems that consume less energy to provide the same amount of illumination
• C. Lighting systems that are more expensive to install
• D. Lighting systems that use only incandescent bulbs

Answer: (B)

"Energy-efficient lighting" refers to lighting systems designed to consume less energy while providing the same or greater amount of illumination. This approach not only reduces electricity bills but also minimizes the environmental impact by decreasing demand on power plants and reducing greenhouse gas emissions. Energy-efficient lighting options often include technologies such as LED (Light Emitting Diode) and CFL (Compact Fluorescent Lamp) bulbs, both of which provide significant energy savings compared to traditional incandescent bulbs. They deliver the same level of brightness while using a fraction of the energy consumption, making them a preferred choice for those looking to increase efficiency in their lighting systems. The other options do not align with this definition, as they either suggest increased energy consumption, higher costs without justification, or limited technology choices. Understanding the benefits of energy-efficient technologies is essential for making informed decisions about lighting that promote sustainability and cost-effectiveness.
