Which statement about green IT is true?

• A. It concerns only the procurement department and does not affect IT operations.
• B. It emphasizes maximum hardware performance regardless of energy use.
• C. It sacrifices performance to save energy and environmental impact.
• D. It reduces energy consumption, waste, and environmental impact while maintaining performance.

Answer: (D)

Green IT is about making information technology more efficient and sustainable across its whole life cycle—cutting energy use, reducing e-waste, and lowering environmental impact while still delivering the level of performance and service users expect. This approach targets the entire IT footprint, from energy-efficient hardware and smarter data-center cooling to virtualization, smarter procurement, and responsible end-of-life handling, all without compromising what the organization needs from its IT services.

The statement that best captures this is the one that says energy and waste are reduced while maintaining performance. It reflects the goal of achieving efficiency gains and environmental benefits without sacrificing service quality, reliability, or capacity.

The other options miss the breadth or intention of green IT: it isn’t limited to procurement or isolated from IT operations; it isn’t about pushing hardware to the utmost performance regardless of energy use; and it isn’t about sacrificing performance to save energy.
