How to Save the Planet Without Leaving your Desk!
summary
Cloud data centers already use about 3% of global energy and could reach 20% soon; migrating from local racks to shared cloud reduces idle waste and one real customer shrinks infra to 1/8 by switching to reactive architecture. Practical fixes include switching JVMs to OpenJ9, enabling class cache sharing (demo shows startup drop from 12s to 2s), using serverless or Quarkus to cut image sizes, and shutting unused Kubernetes clusters to save money and energy.
