Carbon intensity update for 19th Nov 25

Keeping track of carbon intensity is key to making smarter, more sustainable energy choices. At Jaxi, we’re committed to helping you stay informed about the UK’s carbon intensity trends so you can better plan when to run your energy-intensive appliances. Here’s the detailed carbon intensity update for 19th November 2025.

UK Carbon Intensity Overview for 19th Nov 2025

Carbon intensity refers to the amount of carbon dioxide (CO₂) emitted per kilowatt hour (kWh) of electricity generated. Lower values mean cleaner energy, while higher values usually indicate greater reliance on fossil fuels such as coal or gas due to high demand.

Midnight to Early Morning (00:00 – 06:00)

During the early hours of the day, carbon intensity stayed at its lowest levels, ranging from 74 to 99 gCO₂/kWh. This is an ideal time to run appliances like dishwashers, washing machines, or charge electric vehicles if you’re looking to reduce your environmental impact.

Morning (06:00 – 12:00)

As people started their day and energy consumption increased, carbon intensity rose from 142 to 162 gCO₂/kWh. This period saw a typical morning spike in demand, leading to more non-renewable sources being used to meet peak electricity requirements.

Afternoon (12:00 – 18:00)

The afternoon brought moderate carbon intensity levels, fluctuating between 130 and 175 gCO₂/kWh. Energy usage remained steady due to ongoing commercial and industrial activity. Consider postponing non-essential electricity use during this window to help reduce stress on the grid.

Evening (18:00 – 23:00)

In the evening, carbon intensity began to decline gradually, dropping from 176 to 120 gCO₂/kWh. As households wind down, electricity demand decreases, allowing lower-emission sources to play a larger role once again.

Late Evening (23:00 – 00:00)

By late evening, carbon intensity returned to cleaner levels, reaching as low as 83 gCO₂/kWh. This is another optimal period for eco-conscious energy consumption and appliance use.

Why Carbon Intensity Matters

When electricity demand is high, and renewable sources like wind and solar are insufficient, the grid compensates by activating fossil fuel-based generators. These produce significantly more CO₂, raising the overall carbon intensity. By adjusting your energy use based on carbon intensity updates, you contribute to a more sustainable grid and a healthier planet.
