Carbon intensity update for 6th Nov 25

On 6th November 2025, the UK experienced varying levels of carbon intensity throughout the day, highlighting the importance of tracking energy usage to reduce carbon emissions. At Jaxi, we aim to empower our users with real-time updates so they can make informed decisions about when to use high-energy appliances to support a more sustainable electricity grid.

Midnight – 6:00 AM:
The early hours started with a moderate carbon intensity, beginning at 116 gCO2/kWh and gradually increasing to 191 gCO2/kWh by 5:30 AM. These lower-intensity hours are ideal for running appliances like dishwashers or charging electric vehicles.

6:00 AM – 12:00 PM:
As the morning progressed, demand on the grid increased, pushing carbon intensity into high levels. Emissions started at 204 gCO2/kWh and peaked at 221 gCO2/kWh just before noon. Energy consumption in this window contributes more heavily to carbon output, so it’s better to avoid non-essential usage during these times.

12:00 PM – 6:00 PM:
The afternoon saw continued high to very high carbon intensity. Levels rose from 221 gCO2/kWh, reaching a peak of 256 gCO2/kWh around 3:30 PM. The most carbon-heavy period of the day occurred between 3:00 PM and 4:00 PM, when fossil fuel generation was likely at its highest due to renewable sources being stretched. Reducing power usage during this time significantly helps lower the demand for coal and gas-powered generation.

6:00 PM – Midnight:
Carbon intensity remained elevated during early evening hours but began to decline steadily, dropping from 249 gCO2/kWh down to 199 gCO2/kWh by midnight. Although still considered high, this decreasing trend signals a gradual return to less carbon-intensive production.

Why Carbon Intensity Matters:
Electricity in the UK is generated from a mix of sources, including renewables and fossil fuels. When demand is high and renewables can’t meet it, dirty generators like coal or gas must step in. Monitoring carbon intensity helps you plan energy usage when the grid is cleanest, supporting environmental sustainability and reducing national emissions.

How You Can Help:
– Shift high-energy tasks (laundry, dishwashing, EV charging) to times with lower carbon intensity.
– Use energy-efficient appliances wherever possible.
– Stay updated with Jaxi’s daily carbon intensity reports to make greener choices daily.

Together, small changes in how and when we use energy can lead to a big impact on cutting carbon emissions across the country. Check back daily for more updates that help you stay sustainably powered.
