What it does
The Carbon Intensity API from National Energy System Operator (NESO) gives the carbon intensity of electricity in Great Britain, per half hour, with a forecast up to 48 hours ahead, the generation mix (gas, wind, solar, nuclear and more) and regional figures. Useful for scheduling energy use at greener times. Responses are JSON. Free, no key needed.
