Architecting a Sustainable Future
summary
Measurements show a dishwasher uses as much energy as ten refrigerators, a home router equals two refrigerators and the full home Wi‑Fi stack can equal ten refrigerators costing about €1,220/year; phone chargers still draw ~1 W idle (~half a fridge). Data centers are ~1% of CO2 today but models put them near 20% by 2030. Practical tools include ElectricityMaps for real‑time carbon intensity and the Green Software Foundation’s open Carbon SDK; concrete tactics are demand shaping, demand shifting and light switch ops (turn nonessential environments to zero yields ~50% savings).
