Carbon intensity update for 25th Nov 25

📉 UK’s Carbon Intensity Overview for 25th November 2025

Understanding carbon intensity is key to making smarter, more sustainable energy choices. At Jaxi, we believe in empowering our customers with real-time carbon data so they can plan appliance usage when the grid is cleaner and greener. Here is a summary of carbon intensity levels across the UK on 25th November 2025.

🕛 Midnight to Early Morning (00:00 – 05:00)
This period saw low carbon intensity levels, with values ranging between 94 and 102 gCO₂/kWh. These off-peak hours are ideal for running appliances like washing machines, dishwashers, or overnight charging of electric vehicles.

🔆 Morning to Afternoon (05:00 – 14:00)
Carbon intensity began to rise steadily from early morning, reaching moderate levels around 06:30 (150 gCO₂/kWh). By 07:00, emissions increased into the high range at 202 gCO₂/kWh and remained elevated throughout the late morning, peaking at 229 gCO₂/kWh. This indicates higher reliance on non-renewable energy sources during this period due to increased demand.

🌇 Afternoon to Evening (14:00 – 21:00)
High intensity levels persisted through the afternoon and into the evening, holding steady between 207 and 229 gCO₂/kWh. If possible, try to avoid using high-energy appliances during these hours to reduce your carbon footprint and help stabilise the grid.

🌙 Evening to Midnight (21:00 – 23:30)
While still high, carbon intensity began to fall in this timeframe, starting at 213 gCO₂/kWh and decreasing to 194 gCO₂/kWh by midnight. Although not as optimal as early morning, late-night hours may still offer a relatively better window for energy use compared to peak daytime periods.

🕒 Best Time to Use Energy Today:
The most eco-friendly time to consume electricity was during the early morning hours, when carbon emissions were significantly lower. Planning your energy usage around these times helps reduce demand on fossil fuel-powered generators and supports the broader shift toward renewable energy sources.

At Jaxi, we’re committed to helping households and businesses make informed decisions that contribute to a cleaner energy system. Carbon intensity varies daily based on weather conditions, renewable generation availability, and total electricity demand. By checking updates regularly, you can align your energy habits with green energy peaks and reduce your environmental impact.
