Energy Carbon Intensity

Definition

Average Carbon Intensity

Average number of grams of carbon dioxide that is emitted by energy consumption in a specific time frame (e.g. one hour). Location-based accounting is used, not market-based.

Marginal Carbon Intensity

Grams of carbon dioxide that is emitted caused by an additional energy consumption (e.g. if workloads are shifted to a different time).
