Why is my local energy always red / amber / green?!

You may find that your local supply seems to always be in one particular band. This is likely as a result of the generation in your local area, but also to the time of year. For example, the carbon intensity of electricity has been up to 100 gCO2/kWh lower in the summer than in the winter in the last few years, as a result of increased solar power.
