Good

Good app. Like the landscape mode with toggles for each type of energy source. Would be good to have demand displayed as well.

Really useful

I use this to plan my discretionary electricity use such as washing machine. Also interesting to see the constantly hanging mix of power generation. Very grateful to the app developers for what they have done.

Stopped working

Excellent App and really useful and simple to share with others what the grid Carbon intensity is. However stopped working a week ago and data no longer available.

almost perfect

does one thing really well
one “nice to have”: it would be great if the total would collapse or scroll up when scrolling up the source list, to fit more entries on the display
great app!

FAQ

What does GridCarbon do?

GridCarbon allows you to track the carbon intensity of the UK electricity grid in real-time. It shows you how much CO2 is produced per kilowatt-hour of electricity consumed, which varies based on the mix of power generators being used.

How does GridCarbon help reduce my carbon footprint?

By displaying the carbon intensity of the grid, the app helps you identify periods when electricity generation is cleaner. You can then choose to defer energy-intensive tasks to these off-peak times, thereby reducing your overall carbon footprint.

How often is the data updated?

The carbon intensity data is updated every 5 minutes, ensuring you have access to the most current information about the UK electricity grid's environmental impact.

What information is available on the generation mix?

The app provides a summary of the generation mix, detailing the total and percentage supply from different types of generators. It also features an interactive bar chart showing this mix over the previous 24 hours.

Is GridCarbon free to use?

Yes, GridCarbon is a free application. There are no in-app purchases or subscription fees required to access its features.
