Fighting Climate Change by Building Sustainable Software
summary
Claims that 42% of global carbon comes from electricity and heat and that data centers plus networks use ~2% of global electricity set the stakes. Concrete tactics include placing servers near users, compressing and filtering data, running batch jobs in greener regions, and replacing redundant hot‑standby servers with containerized autoscaling because containers start in seconds vs VMs in minutes and eliminate idle waste (up to 50% of servers idle). Serverless and container platforms cut idle electricity; rewrite hot paths into compiled languages when profiling shows large gains (Perl ~80x energy of C).
