Carbon intensity update for 1st Nov 25

Stay informed and energy-smart with Jaxi’s latest carbon intensity update for November 1, 2025. Understanding when the UK electricity grid is cleaner can help households make greener decisions about when to use energy-intensive appliances.

Carbon intensity refers to the amount of carbon dioxide (CO₂) emitted per kilowatt-hour (kWh) of electricity consumed. Lower carbon intensity means cleaner electricity—typically generated from renewable sources like wind and solar. When demand surges, fossil-fuel-powered generators (like those that burn coal or gas) may be activated, increasing emissions. That’s why timing your energy usage matters.

Hourly Carbon Intensity Breakdown

🕛 Midnight to Morning (00:00 – 09:00)

The day began with low carbon intensity levels, ranging from 36 to 57 gCO₂/kWh. This period is typically powered by base-load renewable sources and reduced overall demand, making it an ideal time for running appliances like washing machines or dishwashers.

🌤️ Late Morning to Early Afternoon (09:30 – 15:00)

Carbon intensity remained low during this window, fluctuating between 33 and 62 gCO₂/kWh. Despite increased activity, a strong contribution from renewables helped maintain cleaner electricity generation.

🚨 Peak Afternoon (15:00 – 18:30)

As energy demand rose, carbon intensity spiked, reaching up to 118 gCO₂/kWh. This shift into the “moderate” category suggests that fossil fuel generators were likely brought online to meet demand. To reduce environmental impact, try to avoid high-energy usage during these hours.

🌙 Evening Hours (19:00 – 23:59)

Toward the end of the day, carbon intensity dropped again, settling between 65 and 95 gCO₂/kWh. While still moderate at times, the reduction offers another opportunity to use power more sustainably.

What This Means for You

Understanding daily carbon intensity trends helps you lower your own carbon footprint and support a greener national grid. By shifting your electricity use to periods of low intensity, you contribute to a more sustainable energy system and reduce reliance on fossil fuels.

At Jaxi, we’re committed to helping you make smarter energy choices. Use our tools to monitor live carbon intensity updates and plan your appliance usage accordingly. Small changes in behavior—like running your laundry overnight or charging EVs during cleaner hours—can make a meaningful difference.
