Carbon intensity update for 21st Nov 25

Understanding carbon intensity is crucial for making smarter, more sustainable energy choices. At Jaxi, our goal is to keep you informed about the environmental impact of your electricity usage, helping you reduce your carbon footprint while saving on energy costs.

Here’s your detailed UK carbon intensity update for 21st November 2025. By planning your appliance use during lower-intensity periods, you can help reduce reliance on fossil fuels and support cleaner energy consumption across the grid.

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

• Carbon intensity began at 213 gCO₂/kWh and peaked at 255 gCO₂/kWh around 6 AM.
• This period experienced high demand, pushing reliance on non-renewable energy sources such as coal.

🌅 Morning Peak (06:30 – 09:00 AM)

• Demand surged, causing carbon intensity to reach up to 260 gCO₂/kWh.
• Try to avoid using high-energy appliances during this time to help ease pressure on the grid.

🌤 Daytime (09:30 AM – 04:00 PM)

• Carbon intensity remained high but gradually declined to around 224 gCO₂/kWh by lunchtime.
• This is a more balanced time for energy use, especially if solar production is strong.

🌇 Late Afternoon to Evening (04:00 – 08:00 PM)

• Carbon intensity slowly decreased from 232 to 202 gCO₂/kWh.
• Although still high, this period marks the beginning of a downward trend in emissions.

🌙 Nighttime (08:30 PM – Midnight)

• A significant improvement was observed, with carbon intensity dropping to as low as 101 gCO₂/kWh.
• This is an ideal time to operate energy-intensive appliances like dishwashers or washing machines.

💚 How You Can Help

Every choice matters. By shifting electricity usage to periods of lower carbon intensity—typically in the late evening or early afternoon—you contribute to a cleaner energy future. Reducing demand during peak hours also decreases the need for carbon-heavy backup generators.
