Green computing practices emphasize energy efficiency through which of the following?

Green computing practices emphasize energy efficiency through which of the following?

• A. Using more paper and printing more frequently.
• B. Purchasing and using ENERGY STAR labeled products.
• C. Keeping devices on at full power constantly.
• D. Discarding electronics without recycling.

Answer: (B)

Green computing focuses on lowering energy use and environmental impact by choosing energy-efficient devices and using power-saving practices. The best choice is purchasing and using ENERGY STAR labeled products because ENERGY STAR is a recognized standard for energy efficiency; devices that carry the label are designed to use less electricity during operation and in standby, helping reduce overall power consumption and lower costs. The other options contradict this goal: printing more increases both energy use and paper waste; keeping devices on at full power wastes energy continuously; discarding electronics without recycling creates more waste and misses chances to recover materials.
