Carbon intensity update for 9th Nov 25

Stay informed about the daily carbon intensity of electricity generation in the UK with Jaxi. Monitoring carbon intensity helps you make smarter choices about when to use energy-intensive appliances, especially during periods when fossil fuels like coal are used to meet high demand. By aligning your consumption with cleaner energy periods, you can play a role in reducing overall carbon emissions.

UK Carbon Intensity Overview for November 9, 2025

🌿 Early Morning (00:00 – 06:00)

During the early hours, carbon intensity remained moderate. The day started at 140 gCO₂/kWh, closely matching forecasted values. By 05:00, actual emissions improved slightly, dropping to 130 gCO₂/kWh, indicating stable energy usage and decent contributions from renewable sources.

🌤 Morning to Noon (06:00 – 12:00)

This period showed a downward trend in carbon intensity, reaching a low of 114 gCO₂/kWh at approximately 09:30 — one of the cleanest times of the day to use electricity. However, levels began rising again towards noon, peaking at 135 gCO₂/kWh by 12:00.

☀️ Afternoon (12:00 – 15:00)

The afternoon saw a notable spike in carbon intensity, reaching a peak of 199 gCO₂/kWh. This was the highest level recorded throughout the day and was classified as ‘high’ intensity. This increase is often due to higher electricity demand and reduced availability of renewable sources, prompting greater reliance on fossil-fuel-based generation.

🌅 Evening (15:00 – 20:00)

Carbon intensity remained elevated through the early evening hours, fluctuating within the 170s gCO₂/kWh range until around 19:00. Gradual decline began thereafter, signaling reduced demand and better conditions for cleaner energy usage.

🌜 Late Evening (20:00 – 23:30)

By the late evening, carbon intensity dropped significantly. At 23:00, it reached just 88 gCO₂/kWh and further lowered to 85 gCO₂/kWh by midnight. This period was rated ‘low’ intensity — an ideal time for energy-intensive tasks like running dishwashers or charging electric vehicles.

Why It Matters

Electricity generation isn’t always green. When renewable sources like wind and solar can’t meet demand, conventional generators may resort to burning coal or natural gas, increasing carbon emissions. Jaxi helps you track daily carbon intensity trends so you can make eco-conscious decisions about when to use electricity.

By shifting your usage to low-intensity periods, you contribute to a more sustainable energy system and help cut down on harmful CO₂ emissions. It’s a simple yet impactful way to support climate goals and promote cleaner energy for everyone.
