On the 10th of November 2025, carbon intensity levels across the UK varied significantly throughout the day. Monitoring these fluctuations helps us make smarter choices about when to use electricity, especially as we move towards a more sustainable energy future.
Why does carbon intensity matter?
Carbon intensity refers to the amount of carbon dioxide (CO2) emitted to generate one kilowatt-hour (kWh) of electricity. When renewable sources like wind and solar cannot meet demand—especially during peak hours—fossil fuel-powered generators (such as coal or natural gas) are activated, leading to higher emissions. By aligning energy usage with times of lower carbon intensity, households can help reduce their environmental impact.
UK Carbon Intensity Overview – 10th November 2025
- 00:00 – 06:00 AM: This early morning window saw low carbon intensity, ranging from 80 to 95 gCO2/kWh. This is typically when demand is low and renewable sources comfortably meet the grid’s needs.
- 06:00 AM – 04:00 PM: As daily activities kicked off, carbon intensity climbed to a moderate level. A peak of 150 gCO2/kWh was recorded around 2:30 PM, indicating increased reliance on fossil fuels due to higher electricity demand.
- 04:00 PM – 07:00 PM: Evening hours marked the highest emissions of the day, with carbon intensity spiking to 185 gCO2/kWh. This period coincides with the evening rush and widespread household appliance usage.
- 07:00 PM – 11:00 PM: After 7 PM, carbon intensity began to fall again, returning to moderate and eventually low levels by 11:00 PM, at around 99 gCO2/kWh. As demand dropped, cleaner energy sources regained their share in the energy mix.
What can you do?
To help reduce your carbon footprint, consider shifting the use of high-energy appliances like dishwashers, washing machines, and electric vehicle chargers to times when carbon intensity is lower. Jaxi makes it easy to track real-time carbon intensity so you can plan accordingly.
Every small action contributes to a cleaner, greener grid. By working together and being mindful of our electricity usage, we can reduce our reliance on fossil fuels and support a more sustainable future for all.
