Carbon intensity update for 17th Sep 25

🌿 Carbon Intensity Update – UK, 17th September 2025 🌿

At Jaxi, our mission is to help you make smarter, more sustainable choices about your energy usage. Today’s carbon intensity levels in the UK have remained largely in the low category, meaning electricity generation has produced relatively fewer carbon emissions per kilowatt-hour (kWh). This is great news for environmentally conscious consumers looking to reduce their carbon footprint.

Here’s a breakdown of today’s carbon intensity data for 17th September 2025 (all times are GMT):

• 00:00 – 06:00: Low intensity – actual values ranged from 86 to 100 gCO₂/kWh.
• 06:00 – 07:00: Slight increase to moderate levels at 100 gCO₂/kWh between 06:00 and 06:30, then quickly returned to low.
• 09:00 – 15:00: Excellent window for energy use – emissions dropped as low as 56 gCO₂/kWh between 09:30 and 11:00.
• 16:00 – 23:00: Continued low intensity, mostly under 90 gCO₂/kWh, with small peaks but no significant spikes.

This consistent low carbon intensity signals that a large portion of electricity today came from cleaner sources like wind and solar. However, during periods when demand is high and renewable energy sources are insufficient, the grid may depend on fossil fuels such as coal or gas-fired generators—leading to increased emissions.

If you’re wondering when to run your dishwasher, washing machine, or charge your electric vehicle, these low-intensity periods are ideal. Shifting your energy consumption to these greener windows helps reduce strain on the power grid and contributes to a lower national carbon output.

Why carbon intensity matters: Carbon intensity measures how much CO₂ is emitted to generate one unit of electricity. Lower numbers mean cleaner energy. By aligning your activities with low carbon intensity times, you’re actively supporting the transition to a more sustainable future.
