Carbon intensity update for 13th Oct 25

Daily Carbon Intensity Update – October 13, 2025

Today’s carbon intensity levels in the UK are significantly higher than average, making it a crucial day for conscious energy use. As electricity demand increases and renewable sources reach capacity, fossil fuel-based generators—such as coal or gas—often step in to meet the supply gap. This leads to increased CO₂ emissions per unit of electricity consumed.

Here’s a breakdown of carbon intensity throughout the day:

• 12:00 AM – 3:30 AM: High carbon intensity levels, ranging from 232 to 248 gCO₂/kWh. If possible, delay non-essential appliance use during these hours.
• 3:30 AM – 11:30 AM: Emissions spike even further with levels peaking at 276 gCO₂/kWh. Morning routines that depend heavily on electricity could contribute more to your carbon footprint today.
• 11:30 AM – 5:00 PM: Sustained very high carbon intensity, hovering between 265–275 gCO₂/kWh. This period maintains some of the day’s highest emission rates.
• 5:00 PM – 11:00 PM: The evening sees a minor drop, yet carbon intensity remains very high around 261 gCO₂/kWh. Consider dimming lights or delaying the use of high-energy appliances.

Why It Matters:
When carbon intensity is labeled “high” or “very high,” it means electricity generation relies more heavily on fossil fuels. This not only increases your personal carbon footprint but also impacts collective climate goals. Reducing electricity consumption during peak hours or shifting usage to periods with lower carbon emissions can make a tangible difference.

Tips to Lower Your Impact Today:

• Delay running washing machines or dishwashers until off-peak hours.
• Charge electric vehicles during overnight periods with reduced demand—check in real-time if intensity lowers later tonight.
• Use smart plugs to schedule appliances based on updated carbon intensity forecasts.
• Consider switching to energy providers that prioritize renewables.
