National Grid, Environmental Defense Fund Europe, Oxford/CSci, and the WWF have developed a forecast tool for the carbon intensity of the current usage of electricity in the various regions of Great Britain:
National Grid, in partnership with Environmental Defense Fund Europe, University of Oxford Department of Computer Science and WWF, have developed the world’s first Carbon Intensity forecast with a regional breakdown.
The Carbon Intensity API uses state-of-the-art Machine Learning and sophisticated power system modelling to forecast the carbon intensity and generation mix 96+ hours ahead for each region in Great Britain.
Our OpenAPI allows consumers and smart devices to schedule and minimise CO2 emissions at a local level.
More here. I’d like to see this tool make its way to the United States, if it hasn’t already.
