At Jaxi, we aim to keep our users informed about the carbon intensity of electricity in the UK, so they can make smarter choices about when to use energy-hungry appliances. By understanding fluctuations in carbon emissions throughout the day, you can help reduce your carbon footprint and support a more sustainable future.
On Thursday, October 23, 2025, the carbon intensity across the UK showed favorable conditions for eco-conscious energy consumption throughout several parts of the day. Here’s a summary of today’s carbon intensity trends and the best times to use electricity:
🌅 Early Morning: Moderate to Low Intensity
From 12:00 AM to 2:30 AM, the carbon intensity dropped from 114 gCO₂/kWh to 83 gCO₂/kWh. This early-morning drop indicates a shift toward cleaner energy sources, making it an ideal time to run overnight appliances like dishwashers and washing machines.
🌤 Mid-Morning Efficiency: Best Time to Use Power
The mid-morning window between 9:00 AM and 11:30 AM continued the trend of low carbon intensity. Emissions decreased from 89 gCO₂/kWh to as low as 57 gCO₂/kWh, making this one of the best periods of the day for electricity usage. If you’re working from home or using domestic electronics, this period maximized both efficiency and sustainability.
🌞 Afternoon Consistency
Low carbon intensity persisted through the afternoon, with levels reaching just 41 gCO₂/kWh by 1:00 PM. This made midday an excellent opportunity for running high-consumption devices while keeping environmental impact low.
🌙 Evening Stability Supports Green Choices
From 8:00 PM to 10:30 PM, carbon intensity remained stable around 50 gCO₂/kWh. This sustained low intensity into the evening gives households another window to use energy efficiently without significant environmental impact.
Why Carbon Intensity Matters: When demand is high, the National Grid sometimes relies on fossil-fuel-based generators, such as coal and gas, which increase carbon emissions. By choosing to consume electricity during periods of low carbon intensity, consumers can help reduce pressure on the grid and encourage the use of renewable energy sources.
At Jaxi, we’re committed to helping households make informed energy decisions. Keeping track of daily carbon intensity helps reduce collective emissions and move towards a greener, more sustainable electricity network in the UK.
Stay updated with Jaxi’s carbon intensity data to know the best times to power your life without compromising the planet.
