Going Nuclear (2025) is my latest popular science book.
It’s available to buy now.

It’s published by Penguin (Bodley Head; UK) and Pegasus Books (US).

 
 
 
Energy is necessary for everything we value in life, and the world will need gargantuan amounts of safe and reliable power to eliminate poverty, decarbonise the economy, and feed entirely new demands like artificial intelligence. Going Nuclear shows where this energy will come from — and not as a last resort, but as the enabler of a new chapter in human progress. This is a thrilling book: vividly written, filled with fascinating facts, and inspiring in its vision for the future.
— Steven Pinker, Johnstone Professor, Harvard University and author of ENLIGHTENMENT NOW
You will struggle to find anyone who brings nuclear power to life quite like Tim Gregory. You can feel the enthusiasm jump from the page. There’s lots to debate, but I challenge you to read this book and not be excited about how we get on and power the world with sustainable energy for the next century.
— Hannah Ritche, Our World in Data and author of NOT THE END OF THE WORLD
A passionate, accessible, and timely manifesto that reframes nuclear energy not as a necessary evil but as humanity’s most promising tool for addressing climate change, energy poverty and a sustainable future.
— Kirsty Gogan, Founding Director of Terra Praxis
His argument is powerful and it would be interesting to see a counter argument by somebody – certainly not a Luddite – who writes and thinks as well as Gregory. But perhaps there is no such person.
— Bryan Appleyard, The Spectator
Gregory is an excellent popular science writer: clear as a bell and gently humorous.
— Dorian Lynskey, Guardian
Skeptics will appreciate this persuasive, technical plea for the promise of nuclear power in meeting energy needs without carbon emissions.
— Wade Lee-Smith, Library Journal
Compelling… This book is a highly engaging and lucid primer on nuclear technology.
— Steven Pool, The Telegraph

I narrated the audiobook version of Going Nuclear.
