Change The articles page has been redesigned and all articles now use a larger, more readable font size. The next stage is to implement a colour coding and categorisation system that relates to the 'Other Sectors' section on the home page. Each of these is a sector that has it's own priority in the decarbonisation of the economy and we want to write and present solutions on each of these. You'll be able to easily navigate around material related to a specific sector..

New New round up of what happened on the grid in 2024 as regards carbon intensity and a league table to show how each region of the National Grid faired..

New More explanation of the actual carbon intensity classifications and visualisation on how these classifications change each year to help meet decarbonisation targets. You'll find this on the About page and the charts are now included at the top of the Visuals page to give extra context for new readers..

Change The introductory text on the visuals page stays closed between visits and can be reopened..

Fix Corrected the carbon intensity value of open cycle gas generation to 651 gCO2/kWh from 394 which is actually the value for combined cycle gas. Either way, gas really has no place major role on a clean grid.
