Sustainable Green Software development
summary
Claim: software can cut emissions by changing architecture and timing rather than only swapping hardware. It presents three actionable levers—energy efficiency, carbon awareness, hardware efficiency—and tools: the Green Software Foundation guidance, the Software Carbon Intensity index, and examples like Microsoft’s carbon‑aware Windows update. Data centers use ~2% of global energy and 3% of greenhouse gases; spatial/temporal shifting and demand‑shaping show measured reductions of 45%–99%. Practices: compress transfers, use stateless design, and track only needed data.
