Carbon intensity update for 10th Sep 25

On 10th September 2025, the UK experienced a remarkable day of low carbon intensity, demonstrating the growing effectiveness of renewable energy sources in powering the nation. At Jaxi, we’re committed to keeping our customers informed about carbon intensity levels so they can make smarter choices about when to use their household appliances. By aligning energy consumption with periods of low carbon intensity, you can help reduce reliance on fossil fuels like coal and lower your personal carbon footprint.

Throughout the day, electricity generation in the UK leaned heavily on sustainable sources such as wind, solar, and nuclear power. As a result, carbon emissions per unit of electricity remained impressively low across the board.

Key Highlights from 10th September 2025

• Midnight to 9:00 AM: Carbon intensity values stayed exceptionally low, with the lowest point hitting just 47 gCO₂/kWh.
• Around 11:00 AM: The carbon intensity reached its minimum for the day at an impressive 45 gCO₂/kWh.
• Afternoon and Evening: Even during peak usage hours, carbon intensity remained under 90 gCO₂/kWh, highlighting the increasing reliability of green energy sources.

These figures are significantly below the UK’s average carbon intensity, showing how far we’ve come in decarbonising the energy grid. Days like these are a testament to the success of national investments in clean energy infrastructure and the positive impact of weather conditions favourable to renewable generation.

Why Does Low Carbon Intensity Matter?

When electricity demand is high and renewable sources can’t meet the load, power grids often rely on fossil fuels like coal and natural gas to fill the gap. These fuels produce significantly more CO₂ emissions per kWh compared to renewables. By using energy consciously—such as running washing machines or charging electric vehicles during times of low carbon intensity—you can actively reduce your contribution to greenhouse gas emissions.
