What is Green Computing?

Quick answer

Designing, using, and disposing of computers and IT systems in ways that reduce energy use and environmental impact.

Green Computing, explained

Green computing looks at the full life cycle of technology. It includes energy-efficient chips and devices, data centers powered by renewable energy and cooled efficiently, software that does more with less computation, and responsible recycling of old hardware.

The topic has gained attention as cloud services and AI workloads increase electricity and water demand in data centers. Practical steps for organizations include consolidating underused servers, choosing cloud regions with cleaner power, scheduling heavy jobs when renewable supply is high, and extending device lifespans. Developers can contribute by writing efficient code, optimizing images on websites, and avoiding unnecessarily large AI models when a smaller one is sufficient for the task.
