Last week, National Grid launched the Green Light Signal, a smart bulb that goes green when your home is being supplied by low carbon energy.

It's a super simple way to see the great progress we're making to clean up our electricity system, and to know when's the cleanest time to put on some washing. In GB, almost half of last month's electricity supply came from zero carbon sources.

This also marked the launch of our Power of All campaign to show how, together, we can make the clean energy transition a reality. I'm incredibly excited to be working on this as National Grid looks ahead to COP26, as a Principal Partner. Together, we can reach net zero.

For those interested in how the Green Light Signal works, it connects to, a carbon intensity forecasting tool developed by National Grid ESO, The Environmental Defence Fund Europe, The University of Oxford and WWF. The data provides regional and national carbon intensity - the measure of carbon dioxide emissions per unit of electricity consumed - of the GB electricity system. This includes emissions from all large, metered power stations, interconnected imports, transmission and distribution losses, and accounts for national electricity demand, embedded wind and solar generation. The regional data is broken down across the 14 geographical regions across GB according to Distribution Network Operator (DNO) boundaries.

This document is really useful to see the carbon intensity of different fuel types: The bulb turns green when the regional or national carbon intensity is low or very low.

Really cool program-- how have customers responded? Are they eager to participate? And when they do, is there any data yet on behavior shifts?

Thanks Matt. We've had positive feedback in general, with people seeing this as a useful tool. There's no data on behaviour shifts, but we'll be coming out with free-to-use tools later this year that will make the Green Light Signal more widely accessible, so we may see more engagement then.

This sounds fun. I live in London - how do I get one?
