Fighting Climate Change by Building Sustainable Software
summary
Claims concrete savings: data centers and networks use ~2% of global electricity, up to 50% of servers sit idle, and Perl can consume ~80× more energy than C. Recommendations: containerize apps (containers start in seconds vs VMs in minutes) and run on serverless/Fargate/Cloud Run to avoid redundant hot-standby VMs, run batch jobs in regions with high carbon-free energy mix, compress and process data at the edge, and profile hot components for porting from Python/Ruby to C/Rust or using OpenJ9 and modern Java (9+) for lower memory.
