The Carbon Intensity App has been built in partnership with the WWF, Environmental Defense Fund Europe and the University of Oxford department of Computer Science.

Our app can be used by homeowners as a rough guide for when to charge your phone, put your washing on or run the hoover round.

It can also be linked to smart devices so you can automate your energy use to coincide with the peaks in green energy production. 

Download the app and find out when the greenest hours each day, available on Google Play Store and The App Store.

We have started work on improving the ESO app and would like to hear from you to help shape what it offers and how it works.

We’re looking for feedback from users to understand how you use our current app and gather suggestions to help us improve the new app.
