green-software Skill

Goal

This skill guides the reduction of the system's environmental impact.

Steps

1. Principles (Green Software Foundation)

1. Carbon Efficiency: Emit the least amount of carbon per unit of work.
2. Energy Efficiency: Consume the least amount of electricity.
3. Carbon Awareness: Do more work when the electricity is clean (low carbon intensity) and less when it's dirty.

2. Architectural Choices

• Serverless vs Always-On: Serverless scales to zero (0 energy) when idle.
• Compiled vs Interpreted: Rust/Go consume ~50% less energy than Python/Node for compute-heavy tasks.
• Data Minimization: Sending less data = less network energy.

3. Operations

• Region Selection: Host in regions with low carbon intensity (e.g., AWS Sweden/Canada > Virginia).
• Joy of Delete: Aggressively delete unused data (don't pay storage energy cost forever).
