Digital Systems & Energy Efficiency: Contradiction or Matter of Course?
summary
Data centers in Germany use about 15 TWh/year (roughly Berlin’s 12.8 TWh), accounting for ~3–4% of national electricity, while algorithmic fixes multiply savings: reducing a hot SAP transaction by one CPU‑second across millions of runs yields tens of MWh per year and scaling 500 developers to optimize 10 transactions each can approach 100,000 MWh, roughly a small city. Practical levers include SAP Carbon Footprint Management, landscape tooling to shut idle VMs, and Gardener cluster hibernation (open source).
