Carbon intensity update for 7th Oct 25

On 7th October 2025, the UK experienced varying levels of carbon intensity in electricity generation, reflecting how our energy usage patterns influence environmental impact. At Jaxi, we aim to help our users make informed choices about when to use electricity based on real-time carbon intensity data. By understanding daily fluctuations, you can plan appliance usage for greener energy consumption.

Carbon Intensity Overview for 7th October 2025

Midnight to Early Morning (00:00 – 06:00)

During the early hours of the day, carbon intensity remained moderate. The measured values ranged from 111 gCO₂/kWh to 185 gCO₂/kWh. This period typically sees lower demand, often allowing a higher share of electricity generation from renewable sources.

Morning to Midday (06:00 – 12:00)

As people started their day, the grid saw a surge in demand. Carbon intensity peaked at 189 gCO₂/kWh between 06:00 and 06:30. After this morning spike, levels gradually returned to moderate, maintaining values between 152 gCO₂/kWh and 178 gCO₂/kWh by midday.

Afternoon (12:00 – 18:00)

The afternoon began with moderate carbon intensity, but a noticeable increase occurred after 15:00. By late afternoon, values climbed again, reaching a peak of 228 gCO₂/kWh as demand increased heading into the evening hours.

Evening (18:00 – 23:00)

The highest levels of carbon intensity were observed during the evening when many households power up heating, cooking, and entertainment devices. Emission rates fluctuated between 185 gCO₂/kWh and 229 gCO₂/kWh. The highest reading of the day—229 gCO₂/kWh—was recorded around 17:30.

Why Does Carbon Intensity Matter?

Carbon intensity measures how much carbon dioxide is emitted to produce one kilowatt-hour of electricity. When demand is high and renewable energy sources are insufficient, fossil fuels like coal or natural gas are used to bridge the gap—driving up carbon emissions. These peaks in carbon intensity are particularly important for eco-conscious consumers looking to reduce their carbon footprint.

How You Can Help

• Shift Non-Essential Usage: Consider running appliances such as dishwashers, washing machines, or charging electric vehicles during periods of lower carbon intensity.
• Stay Informed: Use the Jaxi platform to monitor real-time carbon intensity updates and make smarter energy decisions.
• Support Renewable Energy: Opt for green energy tariffs and support initiatives that promote clean energy development.

Every small change adds up. By aligning your energy usage with low carbon intensity periods, you contribute to a cleaner grid and a more sustainable future for all.
