Visit the website https://grid.iamkate.com and examine the current state of electricity generation in Great Britain. The upper donut (doughnut) chart presents the live energy mix of sources providing electricity to the national grid. The inner ring gives the three main sources – renewables, fossil fuel and others (biomass and nuclear), and the outer ring the contributors to each category. Hover over each segment to reveal the live contributors and their percentage.
You will notice that the combined percentage of the three main categories in the coloured bars doesn’t add up to 100%. This is because we trade electricity with neighbouring countries through interconnectors that transmit electricity both in and out depending on which countries have a heavy need or large surplus at any moment in time.
