Fighting Climate Change by Building Sustainable Software
summary
Data centers and networks consume about 2% of global electricity and up to 50% of servers sit idle much of the time, so the talk argues for concrete changes: reduce network hops and compress data, place servers near users or run at the edge, replace always-on VM redundancy with containers (seconds startup) and serverless functions (function-as-a-service stop-start) to cut idle waste, favor compiled languages (C/Rust/C++) over Python/Ruby (up to 80× energy difference), upgrade Java (8→9 gains ~10%) and consider OpenJ9 for lower memory.
