Four aspects of green computing
- green use: minimalize electricity consumption in electronic devices
- green disposal: repurposing, disposing correctly, or recycling electronic
equipment
- green design: designing energy-efficient electronic devices
- green manufacturing: reducing waste and environmental impact of manufacturing
