Which statement best defines green IT in an Army setting?

• A. A policy for storing backups in energy-efficient locations.
• B. A framework of practices to reduce energy consumption in ICT; example: server virtualization and turning off unused equipment.
• C. A guideline for software licensing and procurement.
• D. A technique for improving network throughput.

Answer: (B)

Green IT means reducing the energy use and environmental impact of information and communication technology. In an Army setting, this involves applying a structured set of practices that cut power consumption across ICT—from data centers to field equipment—without compromising capability. The best definition is a framework of practices to reduce energy consumption in ICT, with concrete examples like server virtualization and turning off unused equipment. Server virtualization consolidates workloads onto fewer physical servers, lowering power and cooling needs and saving space. Turning off unused equipment eliminates idle power draw. These ideas capture the proactive, system-wide approach of green IT. The other options focus on backup storage locations, licensing and procurement, or network throughput, which aren’t primarily about reducing energy use or environmental impact.
