Carbon intensity update for 6th Oct 25

On October 6, 2025, the UK experienced varied levels of carbon intensity throughout the day. This daily update from Jaxi aims to help you optimise your energy usage by understanding when electricity generation is at its cleanest. By aligning your energy use with low carbon intensity periods, you can significantly reduce your environmental impact and support a greener, more sustainable energy future.

Understanding Carbon Intensity

Carbon intensity refers to the amount of carbon dioxide (CO2) emitted per unit of electricity consumed, measured in grams of CO2 equivalent per kilowatt-hour (gCO2eq/kWh). When demand is high and renewable energy sources are insufficient, fossil fuel generators such as coal or natural gas are used—resulting in higher carbon emissions.

Today’s Carbon Intensity Snapshot

Low-Carbon Periods

• 12:00 AM – 5:30 AM: Excellent conditions for eco-friendly appliance use, with intensity staying below 100 gCO2eq/kWh.
• 9:00 AM – 1:30 PM: Another favourable window with carbon intensity ranging between 89 and 99 gCO2eq/kWh.

Moderate Intensity Periods

• 5:00 AM – 9:00 AM: Slightly elevated emissions, varying from 98 to 133 gCO2eq/kWh.
• 1:30 PM – 4:30 PM: Moderate levels, peaking at 164 gCO2eq/kWh.
• 6:00 PM – 8:00 PM: Intensity peaked around 179 gCO2eq/kWh at 7:30 PM.

High-Carbon Alert

• 4:30 PM – 6:00 PM: The highest emissions of the day were recorded during this period, hitting a peak of 194 gCO2eq/kWh.

Eco-Friendly Energy Usage Tips

• Time your power use: Run high-energy appliances like washing machines, dishwashers, and ovens during low-carbon periods.
• Invest in renewables: Consider installing solar panels or using green energy tariffs to reduce reliance on fossil fuel-generated electricity.
• Monitor daily updates: Stay informed through Jaxi’s daily carbon intensity reports to make better energy decisions every day.

Every small action contributes to a bigger shift towards sustainability. With awareness and smart planning, we can all reduce our household carbon footprint and help the UK move closer to achieving net-zero emissions.
