Green computing practices – UGC NET Question

Green computing seeks to minimise the environmental impact of ICT through energy-efficient use, responsible procurement and safe disposal. Using power-saving features like sleep mode reduces electricity consumption, while certified e-waste recycling prevents toxic substances from entering the environment. Together, these actions contribute to sustainability without sacrificing functionality.

Option A:
Keeping devices powered on unnecessarily wastes energy and contributes to higher carbon emissions and electricity costs. It contradicts the goals of efficiency and conservation.

Option B:
Printing every document increases paper consumption and may lead to storage and disposal problems. Digital archiving and selective printing are more sustainable approaches.

Option C:
This option correctly combines energy management with environmentally sound end-of-life handling. It reflects an institutional commitment to both operational and ecological responsibility in ICT use.

Option D:
Rapidly discarding gadgets in regular waste streams increases e-waste and exposes workers and ecosystems to hazardous materials. It is the opposite of green computing.
