J-Fall 2022: Hanno Embregts, Jan Ouwens, Jan-Hendrik Kuperus & Julien Lengrand-Lambert
summary
Panel lists concrete tactics and measurements: move builds to daytime when solar is available, use CloudCarbonFootprint to find wasted instances, prefer serverless for lower runtime waste, and consider Leaf Cloud-style hosts that reuse heat. Cites numbers: renewables at ~11% of power in 2020 with only ~4% new growth, one GB ~3 kg CO2 (4G doubles that), manufacturing emits ~80% of a device’s lifetime CO2. shift CI to daylight, measure cloud footprint, buy fewer longer‑lasting devices
