Energy is Life: Why Environmentalism Went Nuclear follows Zion Lights’s personal and powerful journey: from grassroots green activism to becoming one of the UK’s leading advocates for nuclear energy. In a time of climate crisis, energy poverty and growing demand for clean power, she examines why long-established environmentalists like herself once feared nuclear energy, why many have since come to embrace it, and makes a compelling case for why nuclear energy must be part of the solution. Accessible, evidence-based, and deeply human, this book challenges common myths and invites readers to rethink what it really means to care for people and planet alike. If you believe in a greener, fairer future, this book just might change your mind – and give you hope.
