UK Carbon Intensity Update – 24th November 2025
On 24th November 2025, the UK experienced a fluctuation in carbon intensity levels throughout the day, influencing the environmental impact of electricity usage. By monitoring carbon emissions per kilowatt-hour (gCO2/kWh), households and businesses can make smarter decisions about when to use energy-intensive appliances and reduce their overall carbon footprint.
Carbon Intensity Overview:
The day began with low carbon intensity levels, starting at just 57 gCO2/kWh at 12:00 AM. The early morning hours remained clean and sustainable, but as the UK awoke and energy demand increased, so did the carbon emissions.
Between 5:00 AM and 9:00 AM, carbon intensity steadily rose, transitioning from moderate to high levels. The highest point was recorded at 8:00 AM with 194 gCO2/kWh, largely due to the increased reliance on fossil fuel sources like coal and natural gas when renewable capacity became insufficient to meet demand.
As the day progressed into the afternoon, carbon intensity remained elevated but showed signs of a gradual decline. By 2:00 PM, emissions decreased to 174 gCO2/kWh and continued their downward trend, returning to moderate and eventually low levels later in the evening. Just before midnight, a low of 89 gCO2/kWh was recorded once again.
Key Statistics for 24th November:
- Lowest carbon intensity: 57 gCO2/kWh at 12:00 AM
- Highest carbon intensity: 194 gCO2/kWh at 8:00 AM
- Extended moderate intensity period: 5:00 AM – 4:00 PM
Why Carbon Intensity Matters
When electricity demand is high and renewables like solar or wind are not sufficient, power grids rely on backup generators that often burn fossil fuels, significantly increasing carbon emissions. By planning your energy usage around low-intensity periods, you can reduce your environmental impact and support a greener energy system.
What You Can Do
- Run appliances such as washing machines, dishwashers, and EV chargers during low carbon intensity hours.
- Stay informed with daily carbon intensity updates from Jaxi to make more sustainable energy choices.
- Encourage others to adopt smarter energy habits to contribute to collective climate action.
At Jaxi, we’re committed to keeping users informed about daily carbon intensity levels, helping individuals and organisations use cleaner electricity across the UK. Together, we can lower emissions, support renewable energy, and build a more sustainable future.
