ITPEC IP April 2026 Question 73

Viewing materials on screen and limiting printing — Green IT uses IT in ways that reduce resource and energy consumption and the burden on the environment.

Green IT has two sides: making IT itself environmentally friendly (energy-saving equipment, efficient data centres) and using IT to reduce the environmental load of society and business (paperless work, web meetings instead of travel). Reading documents on PCs instead of printing them saves paper and toner and the energy of printing, so it is a Green IT practice.

Answer (d)

Why not others:

• •(a) — displays that reduce eye fatigue concern the health and comfort of users, not the environment
• •(b) — air showers blow dust off people entering the server room; they protect equipment and the facility
• •(c) — backup systems for disasters serve business continuity, not the reduction of environmental load

Key rule: Ask whether the measure saves energy or resources or reduces environmental load; health, facility protection and disaster preparedness are other goals.
