Going Nuclear

How Atomic Energy Will Save the World

Tim Gregory

A bold, provocative, and knowledgeable case for the importance of nuclear science and how nuclear power is essential to reaching net zero.

What if net zero is not an environmental challenge, but an energy challenge?

In this visionary book, Dr. Tim Gregory challenges prevailing narratives around climate change, arguing that the goal of net zero is not simply to replace fossil fuels with renewables, but to power civilization using sources of energy that do not emit carbon dioxide. He unequivocally shows that only one emissions-free energy source can rise to that challenge: nuclear power.

Going Nuclear calls for decarbonization to be the twenty-first century's Apollo program, illuminating the far-reaching potential of the atom beyond clean energy to advanced medicine, forensics, atomic gardening, and interplanetary exploration. By interweaving scientific optimism, myth-busting data, and ambitious policy, Gregory offers an alternative nuclear future that can meet the shared goal of environmental stewardship and continued human progress.

Dr. Tim Gregory works full-time as a nuclear chemist in the heart of the British nuclear industry.  In 2017, Tim surpassed thousands of applicants for a place in the six-part BBC2 series Astronauts: Do You Have What It Takes?, where he was put through the full rigours of astronaut selection and reached the final three. Since then, he has gone on to present a segment about meteorites on BBC4’s The Sky at Night and has made live television appearances on BBC Breakfast, BBC Look North, and BBC Points West.

Endorsements & Reviews

"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, author of Not the End of the World

“Energy is necessary for everything we value in life, and the world will need gargantuan amounts of safe and reliable power to eliminate poverty, decarbonize 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
