UnverifiedElectricity Maps focuses on average carbon intensity, while WattTime emphasizes marginal carbon intensity.75% similarUnverifiedMarginal carbon intensity reflects the additional emissions triggered by the generating units activated by incremental electricity consumption, and is more instructive for users who wish to reduce emissions by shifting loads.65% similarUnverifiedAn open-source project discussed on Hacker News centers on measuring carbon-aware electricity prices daily across 38 electricity grids.65% similarUnverifiedThe UK's Ofgem is piloting a half-hourly settlement mechanism to bring electricity prices closer to real-time carbon intensity changes.64% similarUnverified同一模型在不同数据中心训练碳排放量可能相差40倍以上，冰岛碳强度约18 gCO₂eq/kWh，依赖煤电地区可能超过800 gCO₂eq/kWh61% similar
