Grab a green energy guided reading set for your school, on us

Teachers: we need your help to arm the next generation with knowledge about climate-saving energy.

We've written our own children's book: "Going Green with Constantine", and we want to see it in classrooms across the UK.

Early last year DK publishing approached us to bring the world of green energy to life in a children's book and this is the result, thank you to them for partnering with us.

That's where you come in.

We've created an über-special guided reading set:

  • 6 of our new "Going Green with Constantine" storybooks
  • An activity worksheet

To help as many kids as possible get their hands on our book, we're offering a set to every primary school in the UK, completely free.

Our book is ideal for young kids aged 8 and up, so we're spreading the word to teachers of Key Stage 2 / Primary 3-6 English classes.

What's Going Green with Constantine about?

This book was a collaboration between DK Publishing and Pete, one of the co-founders of our business. The story puts fascinating facts about green power into terms kids can understand (thanks to a helping hand from Pete's lovely wife Kel, a primary teacher, and their 8 year old son, Cam).

The story follows a curious pink octopus called Constantine and friends on a remarkable tour through the world of renewable energy. It's a quick 20 minute read full of laughs. We've also created some worksheets with activities to help the knowledge sink in after, and thrown in some super cute eco stickers too.

Why are we doing this?


The past few years have been incredibly challenging for all of us. We want to recognise the tireless efforts of teachers in looking after kids throughout the pandemic, and show kids that there's hope for a fossil fuel free future.

The energy crisis has made things incredibly tough for families in the UK, and as one of the UK's largest energy suppliers we're doing all we can to support our customers through it, and building green energy solutions to make sure we never face another fossil fuel crisis like this again.

Long before gas prices skyrocketed, we'd been lovingly crafting this kids' book. It's been our mission since day one to move the world to green energy, and educating the public is a crucial part of that. It's now more important than ever that our future is fossil fuel free: and we want the next generation to know that fairer, greener energy is possible if we collectively fight hard enough.

These books are printed sustainably on demand by the wonderful team at DK Publishing in Scotland.

If you have any questions just pop us an email to with the subject line "School Books".
